Tell your wife that she is welcome for providing you as a sex slave. I will try to do better next time. I was playing around with a new smaller boombox design and sent a pic to my son. He said it needed a bigger woofer, so I sent him this pic. That's a "Diz" joke, if I ever saw one. He didn't think it was as funny as I did.

This is the diagram I was given by Wayne at the Speaker Exchange in Tampa, Florida. I used it and it worked perfectly for the (4) new RF-7III woofers which I purchased. They told me that the original RF-7 and the RF-7II woofers are no longer available. I used a Dremel tool and a very small carbide grinding bit to enlarge the woofer mounting holes. If you use a drill bit, it will enlarge the hole too much and you will end up using a washer because the head of the original screws will fall right through. The holes actually need to be enlarged on one side only, which is why I used the Dremel. I used the same bit for routing out the MDF so that the woofer would seat properly. I actually did all (8) by hand and after sanding the high spots, all four woofers fit perfectly. This was actually very easy to do. I am closing in on 70 years old and I've been diagnosed with Parkinson's. I had one of my carbidopa levadopa pills and a couple brews to calm my shaking hands down and I think that I did quite well. I have taken pictures and will post them as soon as my wife gets home. I'm just learning how to use this laptop. Thanks for allowing me to post and share a little about myself.

Thanks guys. It is a Clearaudio Champion II table with an SME 309 arm and Benz Micro cartridge. The little name placard was a gift from a friend, who owns a CNC machine.

At resonable temperatures the speed of sound is lineary proportional to temperature, in Kelvin that is. If we imagine the air above the fire as a hot cylinder, hotter in the center. If a wavefront hits this cylinder the wave in the middle will accelerate more than the wave hitting the cylinder off center as the path lenght is longer and the air hotter through the center. So the wave will become more circular in the horizonal plane and less sound energy will reach the listener in front of the speaker. So the heat cyliner will work as a lens. The lens action works when the pathlenght through the hot cylinder is a sizable fraction of the sound wavelenths. If the rising air is to deflect sound the soundwaves has to be lifted a significiant amount during the less of 1/100 of a second it passes through the heat cylinder. As there is a vertical heat gradient in the air column that gradient will deflect the soundwaves upwards in a similar to the previous description.

Well , he's Canadian , so there's that .

you only like Shemp.. because he was in the navy

Because I’ve traded a lot of email with him and know he is not rolling around in a ton of disposable income. I gave him the best advice for his situation. I still aggressively promote the driver, but every situation is different.

Hi, I’m brand new to the forum and looking for any help I can get! I’m in the process of picking up a pair of rp-280f for fronts and I have an rp-500c (potentially switching to 450c in the future) for a center. I’m only planning on running a 3.0 setup and would only really expand to 5.1 based on my current room configuration. I’m debating between the Denon x3500 vs the Yamaha a1080. The setup will be used for a mix of movies and music. I’ve heard so many different things between the two receivers that I don’t know what to do. The Denon is cheaper, but I’ve heard my friend’s Yamaha receiver (driving energy rc-50 and lcr) and the speakers sound great so i like the Yamaha sound if it were, but is it worth the extra cost? I can get the x3500 for around $500. The Yamaha is around $700-800. Or would they both be overkill?

Finally picked up a nice pair of Cornwalls. I think they're 1's, as the serial numbers are stamped into the wood. The factory stickers are in poor shape. 23U132 and 23U130. Oiled Walnut with new Bob Crites tweeters. They have also recently been recapped though I have no knowledge of what went in. I have all the original parts. The grills need new cloth. They each have some minor tears and marks but nothing heinous. The cabinets are in fair to good condition. They each have a few nicks in the veneer but they look great from across the room. Blasted them for two days an old Sansui 5700 so I could A/B them with my CF-3s. Every time I compare my CFs (my first Klipsch) to new speaks I wonder why I ever kept buying speakers. I love the CFs and they still make me smile. But these Cornwalls are a marked improvement. So far, not as much Bass response but the mids are scary bright and FULL. It sounds like I put four speakers in the room and not just two. I just wired them to my Fisher 500B. So far, great. I think the thing holding them back is the room is too small. Guess I need a new house. 700 Bucks. - Happiest guy in the hood!

Freaked me out a little the first time. I felt, like you did, that something broke. Once the fire burns down and a few more beers later, you hardly notice.

The fostex horns are radials. Parts Express has the plans on their site. http://techtalk.parts-express.com/forum/speaker-project-gallery/57424-here-is-construction-plans-for-fostex-type-of-h400-wooden-horns

I run a 4.1 setup (cornwall mains) with a Yamaha rx-v685 I picked up on sale @ $450 from an authorized vendor. I'd say pick up a Denon or Yamaha AVR, whatever you can find at the best deal new. Be careful and make sure whomever you purchase from is an authorized dealer. Sometimes you can find a cheaper price (especially on ebay) but not an authorized dealer, and any warranty claims could very well be denied by manufacturer. Many guys here on the forum like Marantz units too. Very pleased with my Yamaha, 90 wpc @ .06% thd two channels driven, can play digital files from a usb flash drive and not have to have the tv on for file navigation, YPAO sets up your speakers automaticly like Audessey in the Denon units. Ridiculous ability for settings, and the 685 allows for 8 "scene" settings in memory, diff input, tone settings, speaker settings, and on and on. Whatever you purchase, I would advise to print out owner's manual @ a local store as most of these AVRs do not come with printed manuals from the factory any longer. For example my 685 manual is 189 pages printed. It cost me $15 to print @ my local UPS store. But great being to read and reference the manual while listening or tweaking settings. Just depends on what features you value. Being able to play FLAC album/music files from a large usb drive and being able to negotiate the folders/files without my tv on (via the AVR display) is a huge asset to me. One scene button and its powered up and the music is playing. One asset of buying at Crutchfield on line is you can purchase an AVR, try it out for 50 days and if you are not pleased or want to try out a diff unit, you can return it for a total out of pocket cost of $10. I tried out an open box Denon unit from them then returned it. Return process was a piece of cake. PS...i had the RP-280s just before the corns. 280s for the price are hard to beat, was very pleased with them. Many days I questioned my choice of returning them and spending much more $.

They make watches that use batteries? Beer = Dupont Saison in a DFH glass, blasphemy I know but I don't think Sam would mind. Watch = Helson, small boutique company from Europe that only sells online. Most would never see one in the wild or know the name. https://www.helsonwatches.com/shop.php Lots of their watches are tributes/knock-offs of classic dive watches. For example mine, if in black, would look suspiciously like a Blancpain Fifty Fathoms....but I'm not trying to fool anyone with that illuminated skull. Just a weekend goofing around watch. Back to my Breitling, Black Bird Big Date for work today. Just the glass

Thanks Mike @dirtmudd You started my day with a laugh.

Where do I begin? This is a true story about a crazy adventure where I found myself in a bad predicament on a very long isolated section of the Coosa River in South Alabama about 35 years ago. I was 21 at the time. Two of us had set out to do some fishing one morning before my buddy (Scott) had to report for work at 1pm that day. We headed to the river before dawn that morning. Stopping at Winn Dixie, we got BBQ corn chips and diet cokes for the trip because those items were on sale as a buy one get one free. That was all we had to eat or drink. Putting in at Pop's Landing, we set out to catch some bass. We went about 17 miles down river with the current in a boat friends lovingly called the "apparatus". It was an old 14' aluminum boat with a 40hp Evinrude outboard. Unfortunately it was a cobbled together thing the two of us created where the person in the front operated the throttle while the person in the back did the steering. So it took two people to even operate it. We were a long way from any houses in a very remote area of the river (think the movie Deliverance) when we discovered the outboard would not crank! We worked and worked on it until about noon when Scott declared that he had to get back for work. We looked at a map and he struck out through the woods for a road about 2 miles away through a dense forest. He agreed that he would come back for me at the original boat launch after he got off work at 10pm that night. That would be putting him back at the launch at 11pm or so. It was my job to somehow get back there over the course of the next 11 hours. We had already been in the small boat 5 hours. I had a trolling motor and two hot batteries and that was it. I worked against the current with that trolling motor all day. I stayed close to the bank as much as possible to conserve battery power. I ate corn chips and drank diet coke. It was really hot in a beat down sun with no clouds. Longest fishing trip of my life. All alone, I stayed after it all day. It was slow going, so I fished as I went and even caught 18 bass as I made my way. It was tough though not knowing whether I had enough battery power to even get back. At 11:15 that night I finally made it back to the boat launch and my buddy Scott was waiting for me with a Burger King Whopper, fries, and a drink. I had a terrible sun burn and still to this day can't hardly stand to eat bbq corn chips. I guess I got my fill of those that day.

The "Burninator" strikes again.....it's called the Trogdor effect.

That is nose to tail. Seemed funny when I read your post cause I've been in both so I googled them. Each serves their purpose well but that Blackhawk is a great ride. Slipped up in one again last summer a couple of the pilots were getting their flight time in.

Only Kiss that I ever bought. It got eaten years ago, & I picked up another copy last year.

That rc plane moves and sounds kinda like a bumblebee! The Sikorsky Sky Crane is something to see and to feel maneuvering around. In the 90s staining/painting the Polynesian at Disney they replaced the rooves of all the buildings. We'd have to take long lunches the days the helicopter was bringing the large raised ridge roofing from an island to the setup place on each building for the roofers to use. Yea, remember how you could feel the 60s cars coming? That copter was powerful and built back then too, shook the ground better than a 426 Hemi-Bird did! Over a dozen per side it was that they used.

Reminds me of a flight I had through a T-storm - at the time I would have sworn we witnessed the same maneuvers— ✈️

I own the IV, used to own the III (loved the III). The IV is improved all across the board. Much nicer high end that is sparkly, expansive and adds more life over the III, which sound duller in comparison. The midrange is beautiful in the IV and improved on the III. Voices have texture, life and project out in a lifelike way. The Bass...still sounds sealed to me but has deeper bass. It is still as tight as the III in my room. Two feet out into the room. I get a deeper bass output over the III and as a result these speakers sound just so well balanced. The soundstage is wider, imaging is improved and these can do the 3D holographic thing very well. Better than my Dynaudio Special 40's, of which I just sold as I much prefer the H IV. The port is a good thing and bass is as fast and tight as I have experienced. No flab, flub and no loose bass. These are simply amazing for what they cost. In fact. I would charge $5k per pair if I made them, and I would be happy with them if I paid $5k. But your room and amp and source will make a huge difference in how they sound for you vs me. The room is the biggest factor. These are the perfect size for my room. Tried them on stands, as I did with the III. Just as with the III they sound much worse on stands and sound just right as they were designed to be, sitting on the floor. Anyone who has the III and is thinking of upgrading, I urge you to listen or demo if you can. As with all of these Heritage speakers, the Heresy IV is a lifetime speaker. If you have a smallish room (Mine is 12X13) they are unreal, without a sub. I'm not a fan of subs, even expensive ones, for 2 channel so I am thrilled that these do just perfect without one in my room. Larger room? Add a sub or go up the chain to the Forte III or Cornwall IV. Bottom Line? This is a fantastic update to a legendary speaker. Well worth the $3k price tag. I have had speakers in here that cost anywhere from $250 to $40,000. These Heresy IV's are some of the best I have had here. I use a Vinnie Rossi L2i SE integrated amp with 300B's, the L2 DAC, a Zen MINI MKIII streamer with Phoenix USB Reclocker. SwissCables Diamond for speaker. The IV's also scale well. The better you feed them, the better they will sound.

I have the opposite problem here in the cold part of NA. For about 4-5 months of the year I have to run a Humidifier. With out it my 900 sq. ft. apartment gets down to 30% (and less) in the cold months cause the heat is constantly on to some degree. I usually add about 1-2 gallons of water to it daily to keep my humidity at 40-45%. Anything more or less is uncomfortable.

After the listing has expired the attached photos will survive.

Did you use the term "over priced" to get more attention? They don't seem overpriced to me. This is what it costs to make a Super Heresy 2.0!!

It's been over a year since I last did a room tour of my 7.2.4 Klipsch LaScala Home Theater Room. A lot has changed since then so I finally took the time to provide an update on my setup as I have made a lot of improvements over the past year. With this tour, I wanted to share much more detail than I've ever shared, especially in the area of the custom cabinet that my friend built. As always, my room is a continual work in progress but I am extremely pleased with how it has evolved over the past 13 years when I began building this theater room. Enjoy!

Yesterday(2/16/20) I purchased a pair of Klipsch RF-7's knowing ahead of time that they were in need of new woofers, grills and veneer. I purchased them because of the price and I enjoy having a project to work on in my workshop. So, could someone in the Klipsch Community tell me where to find (4) new woofers and (2) grilles? I'm aware that the K-1089 woofer has been discontinued but, are there other replacements available? I thank you very much for any help which you can give me.

And almost magically the answer presents itself once again on the Klipsch forum! Thanks BSM.:)

I recently spoke with a local gent who is into DIY audio and speaker building who has started to produce "exact clones" of the Fostex H400 wooden horns. From the pictures he's shared, they look exquisite. Very nice craftsmanship. He wants to visit me shortly to show off his wares and hopefully try them out with LaScalas. He says that the current fitting is for a 1 3/8" driver. I believe the cutoff frequency of the horn is 455Hz (though everywhere online seems to indicate 455kHz!). I understand this would mean that it should cross over to the bass bin somewhere around 800Hz, whereas the K400 + K55V is 400hz(?). He told me that he's be ready to build the H200 horn which has a 240Hz cutoff and 2" throat, could this be an interesting candidate for a 2 way system? My main question, is there any danger in temporarily trying these horns out using my (spare) K55Vs in this horn using AA crossovers? I understand it's not ideal and wouldn't be a long term solution. I'll be sure to take some pictures of these homemade horns and share. Daniel

Thanks for the alert. My son is living down there now.

FOR SALE: GORGEOUS 22" Round, McIntosh Labs, Curtis Clock, Neon Clock Made custom for me by Curtis at Curtis Clock. What makes this clock special? I asked Curtis to build me the exact clock that he gifted McIntosh a few years back that hangs in their front lobby (picture below). JUST SO NO MISUNDERSTANDING - MY CLOCK DOES NOT HAVE THE BLUE METER GRAPHICS. If I remember, correctly, Curtis told me he only produced 2 of these and he promised McIntosh no more. FYI, I believe clock #2 was sold on the Klipsch forum a few years back. Since Curtis couldn't build me the EXACT clock at the Mc factory, he got very close by just leaving off the blue meters. The clock has a chrome and black painted bezel and is exactly as I received it from Curtis. Since these are custom made, you might find some very, very small imperfections here and there. I have 3 of his clocks in my home - his clocks are truly artwork. The clock is absolutely beautiful with blue and green neon. Power cord is approx. 5' long. The neon lights have a dimmer knob as well (I'm not 100% certain, but I believe Curtis has stopped building this feature into his clocks due to cost - if he is still doing, I would guarantee it's a premium). My home is smoke free home. Only selling as my wife and I just moved into a new home and no longer have a home theater (where this hung for about 2 years). The neon was only turned on a handful of times when we had parties at our home. Kills me sell this, but I simply have no room to display it. S550.00 COD or $566.00 if by PayPal. For now, this is for pick-up only at my home is Crown Point, IN. I had Fed-Ex pack and ship a similar size Curtis Clock a few months back out to CA and it cost me $250.00! Lesson learned. Thank you for looking! Jon

How can an Italian company that had these in full production in the mid 2000's be in violation of a U.S. patent that wasn't granted until 2010?

Update! With only a few hours left the eBay seller sent me a message saying she was ending the auction and starting again on Wednesday. She said because people wanted more pictures. Can they do that?

If you burn MDF, will it affect the sound differently than burning plywood / hardwood?

Yamaha then over Denon. Look for sales and open box Specials. Just make sure to Have the features you may Want.

One kinetic energy affecting the other.

Thank goodness for friends. Another old friend gave me the framed business card, but only after he made sure to keep one for himself. At 26 years old, I was too shortsighted to keep any cards or photos of that endeavor when I sold the business for $4,000 in 1976. Thanks to good friends I now have tangible tokens of the memories, not to mention high frequency hearing loss. I didn’t build the four SKhorns, they were factory built. I did build a pair of 7s for my friend and mentor regarding Jazz, Blues, and R & B. I also pointed many others to their own Speakerlab experiences. Thanks again, and my wife thanks you too.

Why not? The rising air ought to divert sound waves upward quite nicely, coupled with the heat...

The title says sold, so...

Oh these would certainly benefit from a good clean and oil. Yes, they can sound good but i find them quite upstream dependant. I need something with tone controls lol!! None of my tubes are as enjoyable as they should be.

Thanks all, speakers have been sold!

Well, here she is boys. We are not 100% done, and I am not done with the center channel, but this is my view currently and I am well pleased.

That Luxman is absolutely gorgeous. Way out of my budget, and I haven't heard much about their DACs, but there's no reason it shouldn't be as good as their amps.
