  1. I have a set of series 1s that I had 3 speakers and 1 had a very poor cabinet while the other 2 looked better still needed to have cabinets restored. I decided to mirror finish black lacquer 2 and use the 3rd to make a center channel that would look more like a modern style center using both horns and opted for 2x 6.75” DCM dual 5.5 ohm VC woofers removed from a pair of large bookshelf's. I had to fabricate the entire cabinet and crammed everything in as tightly as possible without loosing strength on motorboard. I used typical techniques for cabinet design with dato cuts to groove sides around motorboard, all block backed seams, 45s on sides inset back piece. All 3/4” 7 layer oak veneer plywood  with no voids. Cab is 100% perfectly square, solid and sounds great, crossover was used with minor tweaks, all caps were tested using ESR meter and were dead on.

     

    Since the woofers are a 5.5ohm load, I added a 15 ohm 10watt resistor to the woofer out put to impeedance match it to retain proper crossover point. I also moved the mids and tweeters down 1 setting on the autoformer to achieve a better sound output that very closely matches the 2 others. Al 3 had the drivers moved to the front of the boards. To keep motorboard strength I did not inset the drivers, I also moved them as close as possible to each other. To mount them on the front required the horns backside of the flanges to be flattened since they are cast with a thicker area in the center of the side flanges that tapers out towards the top and bottom flanges.There was a piece of textured hardboard precision cut to fit over all drivers on all 3 to give it a very different look and make the drivers appear to be flush mounted. All frond edges were rounded to reduce deflection further. 

     

    This design and fabrication took about a week then 2 weeks to finish the cabinet exterior. The other 2 have not had any crossover changes and all caps tested exactly perfect.  This set of 3 sounds better than my series 2 set by far. I would like to sell all 3 or even 5 including the series 2 set also redone in mirror finish black Lacquer. Since I did make the most creative design I could think of the set of 3 really needs to be sold together.

     

    I have named them the Heresy Tiki Series 1. Asking $1000 for the set of 3, $750 for the series 2 set, all 5 for $1500. There's about $750 just in paint and supplies, plus 4 months of all day every day labor that went into these, all 4 regular sized speakers are using all original parts, all caps were tested, all original wires but the series 1 set has updated binding posts.

  2. Working with new wood is a breeze, I fabbed a new cabinet for a KG2.2 and had it completely done in 2 days. Making an exact, basically undetectable copy was very simple to do when reusing the motorboard. I think the cabinet took 8 hours from start to ready for paint. My cabinet ended up ⅛” smaller since I had to squeeze all pieces out of 1 piece of left over wood that had an unsquare edge that I didn't notice before I started cutting. But was able to save it.

       Anyone who has made their own cabinets knows how important it is to have a saw that is set up to make perfectly square cuts. I was a sheet metal worker that did tons of layout work and repetitive cuts and bends to make polished 18ga (about .05” thick) stainless steel open edge weld seams. There could not be any gap on weld seams and that type of layout tolerance makes for perfect speaker fabrication.

    Here's the KG2.2 done.

  3. I tried several times to remove it and you can see how it came through all strangely reconstructed, I had no intentions of changing anything and have no idea how it even ended up there and had to leave it. I thought it my not actually end up posting it like that so I just looked to see and wanted to send a message to the site asking about it.

    ZINDA89----please never change the text of my posts ------I am the only one that writes my posts -

    I started typing ”first” and it didn't appear where it was supposed to, I tried to correct it but there was no way to change it, I don't even know how they happened, I, sorry but I had no control over that and still can't figure out how it happened?

  5. First thing I found that was needed is a proper stand that you can mount the speaker on. I made one using stuff I had laying around. This is the main tool that allows you to keep the speaker suspended while working on it. It will allow you to rotate it while you work since you cannot set the speaker down on any side while you're working. 

    Once that's built, then plan on picking up an assortment of Sanders, a peanut grinder is needed for tough stuff, I also use a sander an old craftsman 1/2 sheet sander, 4x ⅓ sheet Sanders and 3x palm sanders (all loaded with different grades of sandpaper) I also have a a powered hand planer which I found to be very useful on water damaged wood. Sandpaper grades from 30 to 3000, stacks of each of them 30-60-80-120-180-300-500-1000-2000-3000 seem to work the best. Do not get harbor freight paper or you'll get nothing done, it simply doesn't release the paint from the grit. I also have 4 polishers, small 6” dual action, work ok but I found that a right angle variable speed drill works better than any expensive polishers. More torque, better speed consistency, youll need pads and covers, rubbing compound, polishing compounds pastes ect... Some files, scrapers, plastic spreading tools, Bondo, wood filler. Wood sealer, primer, all sand paper needs to be wet sanding, all paint needs to be lacquer and nothing but lacquer or youll be scraping it off and starting over.

      Sanding blocks for hand sanding, long straight edges for checking top levelness and straightness across entire surface. Grinding discs, baking soda and crazy glue or finishing nails and Bondo for rebuilding edges. When you get these things rounded up then you can get started, contact me after you have these required tools and I'll help you in another thread since it will be quite involved and you will need 3 more things before you get started, unlimited money, you cannot do this and expect it to be done for cheap, your first time, 1 speaker will probably end up costing well over $300 in paint and supplies, it will cost less as you get better. My first set of big speakers like these was over $500 and 500+ hours of my time. The 2nd thing you need is time, you can't rush it, you need to do  little bit then wait and see what happens a few days later, your entire work could turn into cracks or peeling or won't dry for some reason , wood warps and changes, edges bubble up and things go wrong tht you will not be able to predict, lastly you need patience, you can't get frustrated and elect everything to go smoothly, it simply will not obey, you can't give up and expect it to finish it's self, never has, never will. You'll need to read even more than I can tell you since others have done this more than I have, what they did and how they did it will vary. No one way is the best, it comes down to what's available and the condition of the wood. 

      Guitar refinishers have knowledge on working with smaller surfaces using different techniques that also need to work on rounded surfaces, there's a bunch of info in those forums. Many things they do doesnt transfer to larger objects due to cost and time. They may restart 10 times and use paints that coat a fortune to cover a smaller guitar body, each time you restart a speaker you just spent $100. I can point you in the direction you need to start but youll have to put in the hours of trail and error to get anything done.

    I Always wanted to reach that type of Finish - PIANO BLACK -----can you please tell us how you did  it ------I apologize for asking , but Man , are these beautiful

    Sorry.

  7.  I used a peanut grinder along that entire edge on all 4 sides and down the back edge where water ran repeatedly, probably from a wife who had plants on top of the cabinets before they were put in the garage where or basement until it flooded and really took a toll on the cabinets. They didn't appear to be that bad until I decided to black Lacquer them and after pealing off the veneer using just my hands I knew I had to get the perfectly level and flat across the entire surface on each side. I placed a large framing square on the side and was checking for square to the top and saw that the wood was cupped about 3/8” from top edge to bottom. The square was touching the top seam and bottom seam but had 3/16” gap in the center of the front side edge and when I placed it corner to corner (top front to bottom back on the side piece) I had 3/8” gap in the very center of both sides. The back edge only had 1/8” gap since the back edge was swollen similar to the top and bottom. The real issue was the bottom 2 inches or so was swollen out the most. The center of course had no swelling, as I worked on flatting the sides I also built up the center a bit. On d I was done with the sides I started on the bottom and I got it pretty good all the way around and Eve had a number of layers of black sanded smooth. But I noticed when I sanded along the back bottom edge I heard a different sound. I tapped on the wood and it sounded hollow. Now I wAs nearly done sanding and was ready to start clear coating, which means I was only a few days from completing. I took a screwdriver and poked it around that area that had the hollow sound. I finally drove the screwdriver into the surface with a hammer ready to fill the void with wood putty. After I was done chasing the bad wood and gouging it out as I went along the path. I had a 3/8” deep gorge that was 2 to 2.5” wide across the back edge and halfway up one side where it tapered off and no more bad wood was coming out. I took pictures of it. That entire area had to have a piece cut perfectly to fit into that gouged out area. It took a day just to fit those pieces in and refinish that surface just to end up stripping the entire speaker and started over from square 1.  That cost $100 and 2 more weeks work to get it back to where I was before. Each restart cost $100 in paint and supplies. I have it figured that a speaker this size will cost a minimum (if all goes perfect and it has never yet) of $125 to mirror finish black lawyer 1 speaker cabinet. With no less than 150 hours of labor. That set ended up with 500 hours labor because I used the original cabinets. Had I fabbed my own (which I considered a million times in my head and decided to keep them original) I could have done it in half the time and half the paint and supplies, but they would no longer be Klipsch Heresy's. 

      Particle board or similar wood is very difficult to seal once it's been loosened up by dents or water. The fibers swell when paint hits it where the damage is. It goes in a vicious circle chasing the swelled area until you finally get rid of it, that's whatf355195736.jpg.c7e3e6ab24ea24b46d447b0edc457c6f.jpg you see in that shot and this is what I had to do to get everything back under control, after it already had 25 coats of black on it. It took about 15 tubes of crazy glue added drop by drop with baking soda tossed on top of the drops to freeze it in place. After a few edges you get the hang of it and a seam can be done in an hour or so with perfect results, that edge is stronger than the wood and that seam is now 1 solid piece, there is no line on the edges of these speakers. Then the bottom issue popped up.

     That's why I say do it right the first time and grind all bad spots all the way down to solid wood before you do anything. I learned the hard way that you can't just cover it up. Bondo will break loose with your fingers if you try hard enough, you'll never get the crazy glue to come off, it soaks into the wood and it actually smokes as it does! You can put some anchors in the area to help his the Bondo in place, a few finishing nails with the heads sticking out a bit will offer more reliable grabbing but Bondo isn't very strong and cracks easily when it's over 1/8” thick, it also doesn't always set properly, it's difficult to keep in place and droops after it's applied and gets everywhere. I  found it very hard to work with no matter what I did I only have about 30 seconds of work time and found myself scraping it back off with a knife because it won't sand at all. I used a special file that looks like a cheese grater and I was still hard to work with.large.Image4.jpg.7f093a00984f946500cf4068a091c1e0.jpg

  8. I did complete resurfacing to a pair with this same damage and I can tell you right now that the repair is much more extensive than a simple patch or it will look worse than if you just left it alone. I went for the strongest most durable repair possible and I have tried basically all wood putties, Bondo, glued wood pieces in place of chiseled and ground out notches, I found the best to be using crazy glue with backing soda built up over the damaged area that has been ground down to a stable base . Meaning any flakes or loose materials need to be removed to have a non affected base that has all the original properties of the original wood used. There is no short cut, you will need to completely veneer the entire speaker to avoid making it look like it has been repaired. Anything short of this will simply draw more attention to the repair and if you're going to spend my time doing this you might as well do it right the first time.large.20190525_171956.jpg.a3a8c2dc33a8e9fb919ea99f70f13d8e.jpglarge.158814205_heresy(6).jpg.6e4e27333e0d47f4d423aa5947b2f172.jpg

  9. I have a set of unmarked speakers that have very similar looking cabinets but they have a Brazilian soft dome tweeter and a 5.25” woofer with a passive radiator on the back. I had the laying around for years before I finally tools closer look at them and made new grills and made a new radiator.

     

    They have a crossover that looks like it could be either a simple factory or a home made that was well done as far as how it looks, covered with glue. They are decent sounding but are not good with any real power, maybe 25w, with minimal bass expectations.

     

    They are nothing compared to a set of Infinity RS125 that I paid $10 and refoamed in 10 minutes with $1 foam pieces I had laying around. I bought a ton of foam last year from Amazon before the seller's all jacked up their prices.

     

     I also have a set of obviously home made small sized speakers with Peerless drivers and huge crossovers Iike these, 2 ways but have Peerless k 4 inch woofers and paper tweeters.

     

    I would take a look for a set of good speakers that have bad tweeters and make new cabinet based on the woofers needs and see how they sound when the woofer is allowed to run up till natural roll off, you can always limit it if needed, you could try any woofer that's 8” or larger since you have a mid driver, I would consider a decent paper 10”. I have a few that came out of organs that are surprisingly well made, even an old zenith allegro 10” driver might work out nicely. They made a good woofer but not much else, can be found for cheap.

     

    Most people who are trying to sell organs will simply give them away if you come and pick them up. I had 4 lined up to pick up for free within 5 miles of my home, took 1 day to locate and set up pick up times. Retrieving the drivers is easy, getting the rest of the organ in the dumpster usually takes some time to tear into smaller pieces. They tend to use the same speakers in a bunch of different manufacturers organs, CTS were popular (alnico magnets) you'll find (paper cones) 12” drivers or 2x12” in many organs with an 8 or 10 on the spinner, all are excellent quality drivers. Although many tend to think that those drivers are more for guitar amps, there are more that are designed closer to home speakers than not. Example is the old Omega brand speakers (I believe they were made by DLK) that used CTS 12” woofers, exact same as used in many organs in the late 60s and throughouth the 70s.

     

     You might even get lucky and find some high $ speakers that were part of some of the best organ systems that have separate speaker boxes using 4x 12 or even 15'” or 18” woofers. Plus there  will always be drivers inside the organs as well. You'll find the top brands like Hammond are harder to find for free, but they're out there, just have to keep an eye on ads and after 6 months to a year without any sales is a good time to offer free disposal.

     

    Another source I have found is console stereos, some used higher quality wave guide horn tweeters and 12” or 15” woofers, finding broken units with frozen turntables and wont turn on can result in free pick up as well. Not everything needs to be bought new when there's so much all around you that's being tossed in the garbage out of convenience. 

  10. I had a set of series 1s for 10 years or so, cabinets had typical pealing veneer, water damage to top and bottoms. I originally had plans to black lacquer them and once I got started I realized that there was much more to it than expected. So I did what everyone does and just left them black with grain showing. After redoing several speakers in black lacquer over the years, I decided to do a set of series 2 that were in bad shape and did a complete money no issue type restoration that included rebuilding the corners edges and seams with a much more harder material. It took a good chunk of time and money but they turned out great.

     

    So after I picked up a 3rd series 1 for $30 which had a terrible cabinet and what I found later to be a water damaged but still working woofer, I decided the next project was to fix the bad job I started 10 years ago and turn the 3rd one into a center channel. I also came up with an unusual themed look for these 3 speakers that would set them apart from any other set in the world. I always figure that there's no sense spending time on anything if you're going through the trouble you might as well make it your own creation. A simple veneer job will never be a project I would be planning. I would have a hard time getting excited to do it knowing it will end up looking like so many other thousands of speakers that are out there already. I want mine to be recognizable as my build just from seeing a picture from 10 feet away.

     

      After much thought I had to improve on the original design by removing a few of their weaknesses or slight imperfections without losing the original sound, since they were going to be stripped and I had full control. I felt the best way to start was to move all driver's to the front of the motor board to remove the diffraction that was part of series 1s problems. Not only the diffraction at the edge of each hole but at the cabs front edges. They needed to be rounded or mitered. I chose rounded which may be the harder of the 2 since the paint was going to show any tiny defects.

     

     I opted to work with all original parts once again for the 2 mains which meant completely grinding down all sides to get a perfectly flat and true surface on all sides of the cabinets. Removing any cupping and maintaining edge thickness around the front was crucial. The way that the series 1 are built has the motor board screwed to backing strips (¾“x¾” blocks of plywood) that are stapled around the front inside edges (definitely not the best way to build the cabinet since they offer little strength and lack ability to seal air tight) and they are not cut to be precise leaving gaps at the corners and do not offer an airtight seal. So all seams and connections were sealed with glue and large gaps were filled with Bondo to make them air tight where glue alone could not fill them.

     

     The next issue was the drivers themselves were not made to be front mounted, the casting was made with the side flanges were thicker in the middle than at the edges. This raised area made a V shaped flange on the back side where the seam was and made them not able to be mounted without possibly cracking the the edges of the flanges and also making it difficult to seal and mount evenly. Both the tweeters and mids displayed this casting issue. They had to be filed flat so all 4 sides were level, this took much more time than expected to end up with perfectly flat flanges.

     

      Moving the drivers in front of the motor board gained some interior volume, I also moved the tweeter down closer to the squaker, originally I did this to get them to blend together better and for looks but later realized it was a necessary in order to be able to mount the tweeter without the magnet hitting the backing strip. I had to make the drivers appear to be inset into the board without actually cutting away any material. It also wanted it to have a very original look, a new texture that would make the entire speaker look as if it was made to not be covered up and hidden from sight. I then carefully cut pieces that fit like a glove over the drivers. Great care was used during the trimming of the new cut outs. There's a 3/16” strip of wood left behind the front trim piece between the tweeter and mid just so they seal tight. The tweeters corners were ground to fit inside the mids. Foam tape was used to make airtight seals.

     

     The painting part was no longer as difficult as I had seen on other speakers, the plywood had a better more solid foundation that was much easier to seal especially on the edges. I found it did not need to be ground away and rebuilt as the series 2 cabinets needed. They did have their own set of challenges that needed to be addressed but there was much less ”redoing” as I progressed in comparison.

     

    The center channel needed to be completely fabricated and I drew up a plan for 2 designs, 1 would use a pair of 6.75“ DCM 5.5 ohm dual voice coil woofers and the other was for a pair of 10” woofers single 16 ohm voice coil or a pair of 5.5 ohm dual voice coil. The 10” just called for a cab that was going to be quite a bit larger just to mount them. I went with the DCM and packed everything in tight as possible. I also made the cabinet to fit around the motor board. Grooving the sides and notching the front to make a tight dato fitting that could be glued airtight during assembly. I had a piece of 3/4” 10 ply veneered plywood that was big enough to make the cabinet no room for error. I did the same front mounting and covered the front with the same textured hardboard 3/16” panel, cut to fit exactly as possible.

     

      The ports were from some speakers I tore apart and tossed, I had 2 sets of them no idea what they came from. But they needed to be modded as well to  flare the opening and make them smooth. JB Weld did the trick, I have plans to cover the 12” woofers with a similar metal grill but haven't found the right one. It has to fit directly on the edge of the basket as the smaller ones do. I cannot have a frame under it or anything that's larger in size since it has no room available with the front cover cut exactly to fit. I may have to make my own by hand.

     

      The sound has greatly improved even better than the series 2 by a long shot. I did have to move the autoformer settings for the center channel and added a 15 ohm 10watt resistor in parallel with the mid to smoothen the response. The overall look was exactly what I was looking for and the bonus was the much improved sound. I think I have made a near perfectly timbre matched center with the most unique look possible, all pieces are mirror finish black lacquer (that has become my finish of choice on anything I do now) just to make sure that these will stand out as another one of my creations and very less likely to ever see another in existence. This set of 3 has been named the ”Tiki Series” the mask of the warrior is a very close rendition of my final creation.

    Thanks! Resurrected from severe plywood delaminating water damage, misused, mistreated, abused and left for dead. They were literally trashed! The grills were made from raw materials. Paint is acrylic urethane "hot rod" flat over feather fill polyester primer.

    Sounds like my speakers but mine were cupped about 1/4” on the short sides and 3/8" on the long sides. Plus working with MDF is like trying to paint cardboard and not expecting it to swell up. I had to use a few tricks to seal the seams edges and rebuild the corners.

    I have no idea if those are any good or not. Find someone with a known good meter to check against before trusting it would be my suggestion. I bought a used B&K 885 off ebay and it was still a bit over $400. Some of the Chinese stuff is good and it ought to be since they stole the IP from us and more than likely made it on our equipment on the extra production runs they neglected to tell their valued customers about.

     Yes they did, but they do that with everything now a days! That's just a fact of life that we can't change, it's buy or blow em up! We have to make that choice every day.

    From what I've read they seem to be pretty accurate but it might be hit or miss.

    My favorite thing about online communities is the judgements people make about how people spend their $$$$$ - LMAO - I just wanted a fun project since I am retired and love to try things I have never done before. The project started out as an excuse to learn how to veneer a set of speakers. After people suggested the woofers would look much better if I used shoe polish  on them I had no choice but to replace the woofers as the polish disintegrated the one I tried the polish on. I had no desire to build my own custom designed speakers and I am quite happy with the final results of this project. I do not think I wasted $$$ installing the new crossovers even if it wasn't required because the speakers now look great and sound great. They are still Klipsch Heresy speakers - I have less then $700 into them and they are exactly the way I want them.

     

    To  clarify what I was saying, since you ended up changing out just about everything except the squaker you could have just not bought those speakers for the original $450, but instead bought a sheet of good 10 ply plywood that already had the veneer on it and could have had Lowe's or home Depot cut it for you right away. Then your project could have been altered to fit the speakers you were buying, also your project would have taken a bit longer as you were saying it was moving too fast. Well assembly of the cabinets would have also enabled you to insert bracing and do a bit of research into making those cabinets. I'm not bashing you in any way, I think your speakers turned out very nice. I'm looking at this from the point of view that after it was all said and done you really only have a Klipsch cabinet with 1 true Klipsch speaker in it , Am I wrong? When I started my heresy project my main goal was to make sure I didn't change a thing as far as shape, and mechanics, no new cabinets, no new drivers, reuse every single screw, just make over the very abused cabinets and make them into something that very few if any others have but make sure to keep the the speakers a true Klipsch Heresy but not anything that Klipsch would ever attempt to do. And I'm not saying paint them psychedelic or use product names or pictures, but keep them very classy and enhance their value well beyond their actual worth. But make them appealing and fit into decor no matter what type.

     So I had a plan, see that's the difference, you also had a plan, obviously you knew that they needed some work and you wanted to try your hand at veneer. That's great, you did a fantastic job, as good or better than most who have tried it or have been doing it. To me that's kind of like going to Baskin Robbins and getting vanilla (vanilla is my favorite flavor of any food out there, I will always order anything vanilla, but I will look for the strangest vanilla flavored thing can get before I settle on the generic one), so if I were to veneer a set of these fine speakers I would be hunting for some very unusual grained veneer and consulting experts in the field if need be to find out what to stay away from and why. Then I would contact people who (in this case I would have been on the guitar restoration forums picking their minds on what would really be the ****, what's going to make a statement?) are in the know about working with different woods and stains and colors that can make wood look like nothing you've ever seen before. Techniques that are basically unknown to us speaker geeks. Those guys can provide so much information just by spending a week or 2 reading old forum posts. The old ones are best because they are complete projects that others have chronicled. Their mistakes, their triumphs, their heart breaks, costs, panic and then the alation, the final product done perfect, like nobody else's. Shown in pictures on display for the world to see. The weeks of time, the hours spent searching for the right materials. The lessons learned on the way. It's all right there. 

     I found my way there as I started my project and realized that there was quite a few things that can and will go wrong when dealing with paint. Even if you've painted a bunch of stuff in your life. Plastic Models, Die Cast cars that sold for $100 due to your restoration, wood chairs, Wood tables, metal cars, your own car, maybe somebody else's car, projects at work that were huge. But when it comes to painting a speaker or doing anything with a speaker cabinet you find out that many things can and will go wrong. Each and every time I had to start over was another $100! After 3 times you will want to know why things happen and how to avoid them. But there is no set plan, each project brings its own new set of issues. Mine was 30 year old wood that had water damage with splits in the veneer and  cupping on all 4 sides. I knew that before I started, nobody deals with these obstacles, they simply trash it and make a new cabinet, simple, done, just saved 2 months work and $300 by making a new cabinet. So there wasn't anyone to tell me how to work with what I had. But there are people who work with old wood and make them into pieces of art every day. 

     That's when I thought about guitar restoration, that's how I was able to get started and I had to add my own ideas to apply it to wood that isn't a solid piece, I had seAms and corners and I didn't have a solid piece of wood but rather several joined pieces of MDF to work with. So many things just don't apply. That's where you have to set yourself apart from conventional thinking, knowing that you won't be able to get the answers you need to complete your dream is frustrating and can be costly too. But someone has to be the one to do it first no mater what, if you want to create something that will thrill people when you unveil it you have to power through the disappointments, you can't just give up, you cannot compromise on your dream. 

     When you have a dream and you combine a bunch of hard work long days and many of them with  bunch of money and hope you can achieve some fantastic results. Knowing that your creation is like no other even though you took a very common place item and did nothing accept to change its exterior finish but what you have done is so sublime, so perfect, so satisfying that the look and feel have to be experienced to be appreciated. Mere pictures can only convey the visual beauty so far, the seeing up close and touching it finalizes the senses, it provides a reality to what you just spent 2 months of 10 hour or longer days working on. Putting everything else on hold in your life, that's the satisfaction I'm talking about, not I wanted to try something and it cost $xxxx. The cost is only there because nothing gets done for free, it's not even that the materials were expensive or rare, it's because that's what's it takes to get the job done right, no compromise. I would never simply paint a speaker cabinet without thinking I was making it a one of a kind, the kind of one that people see and they react, mostly in disbelief or shock in the beauty. The more simplistic things are the more the beauty can be seen. That's why my project ended up looking like this, absolutely unchanged every single last screw was used every piece of wire, crossover components etc. I planned on spending around $200 to $300 to achieve my goal and maybe 2 weeks time. 8 hours max each day, that quickly changed, I adapted and stayed focused. This is what I ended up with.

    Wouldn't it be nice to have a specification for design ESR as well as Farad?  A lot of meters get the Farad part close enough, takes something a bit more involved to check the other value.

    I have an esr meter on the way, from what I've read they tend to be the best meters available now based on a kit but now China has picked up the production on them and is selling them in Mass quantities at very low cost. They used to be around $40 for the kit, now they sell for $8 without cases and up, most expensive ones are around $80 but they don't really do anything extra over the $8 models except have a nice case, a lipo battery and loop connector leads to do in circuit testing oh I forgot they also id components, and some have IR sensors readers for audrino and other remote programming. They can decide the signals so users know what the remotes are actually emitting per key press. These meters are really pretty slick and they have been praised by most all the who buy them. Some have input headers onboard to update firmware. Some will only ready caps up to 1000mf while others go up to 100kmf but take a while to display results. Some have color screens others are green and yellow, some come with cases and leads others are still in kit form. Hundreds of sellers on Amazon and hundreds maybe thousands on eBay. I should have mine in a week, I can finally find out what transistors I have when I bought a bag full of brand new in packages (maybe 100 or more pieces) from an old car stereo shop closing sale on eBay about 10 years ago.

I'm hoping they're substitutes for the old MTX and RF car amps that used the "Buzz" transistors. They're supposedly from the early to mid 90s, that's what the other items were dated in the lot I bought. Locking pull out plate by Craig, FM stereo tuner that plugs into an 8 track tape slot, various din cords, etc.. the meter should tell me what it is and give a bias voltage and tell pins at minimum it just depends on what it has on file for this piece. Some items have nearly full data sheet info available.

    Same here...

    I first covered mine in a textured vinyl for $8 a roll and they ended up looking like a pro audio version of the heresy. I tore it off and started my oddessy and what I thought was a never ending refinish. My cabinets were badly neglected. All 4 sides were cupped to a point where I ended up sanding through the veneer trying to get them flat, level and maintain an even thickness.

      But I made sure to reinforce all corners, edges and seams, making them harder and more durable than they were new. No shortcuts, no worries of cost or time, I ended up finding out what worked as I went along. Here's some of my work. Grinding away the seams and corners. Then filling with crazy glue and baking soda, 1 drop at a time. This made them sealed (no possible way to end up with a crack in the paint) and reinforced the edges strength. It was tested by a nearby speaker rolling off a chair and bouncing on the ground while spinning it's sharp veneer edge hit the finished edge directly on the center of the seam edge. It chipped the paint but did not even ding the material. I did end up having to respray the entire cab to fix the chip. But I found out that what I did was worth the effort.

    As a former electronics engineer, old caps will degrade over time-sometimes instantly.  I like to know they have another 30-50 years.  Components (caps, resisters, diodes, transistors, etc) are made better than they were 30-50 years ago.  

     

     

     

     

    I can't totally agree that things are made better now than they were 30 years ago simply because anything that was built between 2000 and 2005 was doomed for failure due to the millions of improperly made capacitors that were used in just about everything. I've seen my share of good caps go bad in modern electronics even Panasonic and Elna brands almost daily I'm tearing something apart that's dated 2000 to 2013 with failed caps, but I have a stack of maybe 10 or more receivers from the 70s and 80s that I use daily and none of them have any bad caps in them. Infact I'll bet I could go to a Goodwill and buy 10 electronics devices dated after 2000 and make sure they all power up, take them apart and I'll see at least 3 with bad caps, and that's not including any monitors. If I picked out only monitors, half or more will have bad caps. I have a crt tv that I bought new in 1983, it still works, I tore apart a bunch of crt monitors that all worked back in 2010, bought a bunch of LCD and led monitors to replace them and over half of them had bad caps! I just tore open a power supply yesterday and all of the caps that were marked "low esr" were bad and no others had issues, I'm going to look for that board and post a picture of it. I had to laugh when I saw the low esr caps mentioned just hours after I saw those. Those are also the culprits that go bad in monitors, i replace them with regular caps and they have outlived the originals by 3 or 4 years now without any failures, those replacements were torn out of old vcrs and crt monitors and tvs from the early 80s to mid 90s they already were in use longer than the caps that they replaced and still work!

    There was mention of believing others that know more about things so they are to be believed based on that fact, let me ask 1 thing, do they have a vested interest in capacitor sales or parts? Because there is such a thing as a sales man, I'm not sure if you ever heard about these guys but they study up on the things they need to say to convince you to buy crap you don't really need and make it sound quite convincing since they are going to be making money from your purchase they have no interest in telling you anything other than their benefits even if they are marginal or even questionable. Because that's what they have to do to make money, they can be very convincing and even make you feel that you are completely wrong if you don't buy into what theyre telling you. That's what makes a great salesman, making you believe they're right and make you willing to argue their point even when it's been proven that what they are saying is simply opinions and when actual tests are conducted using different higher quality caps, in a controlled environment double blind tests show that people cannot hear the difference, it's nearly a guessing game at that point and the numbers cannot even be repeated. There's a sound engineer who heard of this craze when it started a few years back he has a web page and that tells how he wanted to test different caps that were labeled as superior sounding to others. So he built 4 identical crossover networks using different caps and mounted them outside of the cabinets. He then connected them through a ultra fast relay that can switch crossovers so quickly there is no lag in sound, meaning when they are changed there is no delay, it should just sound different when switched. The idea was to have people listen and tell when they heard the difference and which ones sounded the best. He had a stage and a remote to switch the relays all set up and was ready to test it out. He turns on the music gets into position and clicks the button and clicks the button and clicks the button? He figures the relays are not powered up because he didn't hear any differnce but when he walks closer to the speakers he can see the relays are working just fine! End of testing.

    DING DING DING; we have a winner!

    My thoughts exactly;  no reason to change a capacitor that's in spec.

     

    A word to the wise about refinishing; if you try to strip the paint off veneer, any liquid stripper has the potential to loosen the veneer adhesive, then you've got a real problem. Try a dry method first such as a palm sander, on the bottom panel, so if it doesn't provide good results, you won't see it. 

     

     I would not even start stripping any paint off of old veneer, for what reason would you want to do this? What do you think the results are going to be? You'll never get clean untouched wood after it's been painted black! The veneer is too thin to even consided trying to save it. Paint soaks into the grain of the wood and will fill every single hole and sanding it off of a 1/16” thick surface is not going to leave you any veneer. On top of it all, as stated, if solvents are used they will simply loosen the glue and the veneer will peel off.

    Bottom line is, the cost of trying to save what is probably a bad veneer is going to take forever and cost more than simply peeling it off and redoing it right. Plus it will look 100 times better than you'll be able to get that old bad veneer to look no matter how much time and money you spend.

     Or you can sand it down to where the veneer is perfectly flat again, it might even need to sand right through it in spots just to get it all one height, then seal it prime it wet sand, prime again, check for flaws, then 20 or more coats of lacquer, wait a week then sand it to a mirror finish, start at 220 grit, then wetsand with 500, then 1000, then 2000, wait 2 days, then if no flaws appear, shoot 30 coats of clear gloss acrylic lacquer top coat, wait a week, wet sand with, 500, 1000, 2000 and then 3000. Wait 2 days look for flaws, find flaws, strip the entire thing and start over but this time grind all seams and edges away about 3/8" deep using a hard wheel on a grinder. Then rebuilt all seams corners and edges using crazy glue and baking soda, this seals everything and provides a durable tough as nails edge that will last forever. Grind it all flush with the wood and redo all prior steps that you just learned. After a few months of daily work (work on 1 cabinet, then leave it sit and do the other) and $300 to $500 you should end up with something that looks like this.

  18. Just curious if anybody ever tests their capacitors before they replace them? So many are instantly telling others to change out their stock components with overpriced exact duplicates without ever knowing if the originals are out of value in the first place. Many times the caps are chosen by the manufacturers because they did extensive testing to find which ones perform well with those speakers. Tiny differences in internal resistance will affect the way they work. 

     

    When the mention of not hearing any difference was stated, I have to say that I commend you for saying this since most others will never admit that fact and have made up their minds that since they spent a fortune on unneeded parts and spent the time doing it, their ears automatically hear a huge difference. I'm not sure if it's denial and don't want to admit they were taken or jumped on the band wagon just because it's a buzz right now. I have tested all my caps in my old speakers including series 1 & 2 Heresy's, Infinity, Polk, etc even tested a bunch of cheap speakers and have yet to find any that deviated at all from their marked values. 

     

     Looks like your speakers turned out nicely, but is there even any Klipsch parts left? Seems like you could have just started from scratch and made your own cabinets and you would have saved $500 minus the cost of veneered plywood (last time I checked it was $53 a sheet for ¾"x4'x8' 10 ply oak veneer sheets available at Lowe's and home Depot). Plus you would have saved all the time and work prepping the surfaces, time spent looking for veneer, sandpaper and other stuff that went into the veneer job.

     

    You certainly have the skills to perform the task and you could have altered the cabinet size and shape to suit the speaker ideally, but most importantly you could say that it's your own design, because it would be. You'll get twice the satisfaction  when you made the entire speaker, (even though you almost did just that) than simply replacing parts (albeit nearly every single part) out from some manufacturers cabinet.

     

    Just something to consider next time you want to start a project, even though it seems that you have plenty of cash to spend, that $500 could have gone into even better drivers, wires or a nice table saw, router/bits, sander etc..
