  1. Serious humor only. Speaker wire by the roll from Parts Express is fine as far as I am concerned. Finer strands mean you can bend it more times before breaking but other than that all this other stuff is fluff.
  2. Well they have proven that even electrons have weight and if you allow your wire to sag in between supports they will puddle in the low areas. This is why you get that pop when you turn your amps on. Both the transient new electrons and the puddled stagnant electrons create an inrush to the speakers and thus the pop. This is why you should use pure Platinum wires as the specific gravity means the interstices of the atoms is more compacted and will allow for less puddling of electrons. I prefer pure Gold and Silver and best yet Platinum foil capacitors for this reason also.
  3. https://www.ebay.com/itm/BAG-OF-12-1N3996RA-ZENER-DIODE-10-WATT-5-1-V/162807725816?hash=item25e818bef8:g:9boAAOSwa81aNUEy If these are the right ones for crossovers he is selling them 12 for $95.00 which beats the heck out of all the prices I have seen to date.
  4. Well that is what I was thinking. I did not believe him this time since I have a good capacitance meter and I have checked the same capacitors new and then later after being pulled because I was curious to see if heat had affected them. I had to rob some 47uf's and 13uf's to use on a hot jobs and they were not altered at all.
  5. My friend is pretty smart and I used to watch him maintain a whole commissary operation right down to repairing PC boards but I figured he was not right on this one. I had never heard of such a thing so I asked. I figured he had specific instructions for a delicate piece of equipment and projected that to everything else just to be safe. I like the Weller, quick to heat up and quick to cool and works well. Kind of like TIG welding where too little heat means higher total BTU input into the work piece as you struggle to melt metal I find the Weller does the job quick and the field is no different than the bench as the end result is the same and so is the purpose.
  6. Talking to a tech savvy friend of mine today and he was horrified I would work on crossovers with an AC Weller soldering gun. He says he was taught that any solid state component, and he included Zenner diodes in this group, could be damaged by the electrical field of the soldering gun. He says he only uses a butane soldering iron for this reason on basically anything outside of lamp cord. I had never heard this mentioned on the forum before so I ask is he right?
  7. Ok the attachment gives a list of what your year code means and what SHOULD be in your speakers. http://www.critesspeakers.com/crossovers.html will tell you about crossovers and years of production. Use this information to determine whether your parts are original to the build tag or not. Codex_V3_130823_635128700889860000.pdf
  8. Well I don't know about blowing a KD-12 or 13 but I have seen a KD-15 laying in pieces along with the K-48 in the bottom of a KP-320. Typically what I see is cats using the passives for toys and odd things like wives vacuuming off one and punching a hole through it. Kids are tough on them to so you just never know.
  9. I along with others here have had no end of grief finding KD-13 drones for old Fortes. I have been informed that Klipsch has run a new batch of these and they are once again available as OEM.
  10. Sorry I have been busy today. Yes I found lots of stuff on ported La Scalas per your suggestion. I was typing in garbage and getting garbage back.
  11. There is a possibility I will be doing a short job in Boulder in January. If I do get this job I would be very interested in these. I will know more this coming week whether I am getting this job or not. PM me with more information if you don't mind.
  12. So I inquire about some custom built La Scalas with the claim of much lower bass. Since I am thinking of building a set sometime I am always interested in possibilities. Here is the modification claimed to work. " The top section of the speaker is opened up to the "doghouse" with a plate closing up the back which is normally open, with 2 port tubes facing the rear tuned to 30 Hz. This makes the ported section invisible as far as the appearance." Now I know La Scala mods have been beat to death many times over but this is a new one for me. Anyone familiar with this modification to know if it is even possible to do what the claims state?
  13. Those K-42-KP woofers are a pain. Here in Nashville it took many MONTHS to get an old one re-coned and cost about $135.00 to do so. None of the Eminence woofers quite fit that K-42-KP cavity and every time I have used a current Eminence speaker I have had to route the hole out. I have some older KP-250's (1989) and they are much nicer sounding than the II's. You can rebuild the crossovers with Esre capacitors pretty cheap if you can solder. The Crites tweeter diaphragms are worth doing. Pro speakers can be hard to sell if you think you might end up doing so and all the KP-250's I have sold to date had either KP-480 or KP-115 subs to go with them and that is what sold them. I would go and hear a set of these before I spent money on them so you know ahead of time what you will get. EBay is your friend and sell the parts off or sell them as is there. You can always say no to lowballs and you just might be pleasantly surprised. A picture, price and location here just might get you a buyer.

    KP-301 II

    Here are some pictures. These are as close to coming out of a time capsule as you could get and pretty astounding for pro speakers at least 24 years old.
  15. Here is my current setup subject to change frequently depending on what I am working on. Generally it is a pair of Pro La Scalas which are hidden behind the KP-301 II's right now. Second is a picture of my bookshelf

    KP-301 II

    Yes. Well at least they came from Arkansas and the guy met me in Memphis so I did not have to drive all the way. Did the Ti diaphragms make a real difference? I am kind of thinking the magic here is the mid driver. Didn't realize the Chorus and 301's were within a few cubic inches cabinet volume.
  17. Deang, As the other commentor said get a store. I don't like Ebay fees but I have sold everything there from rock slabs to faceted gemstones to used equipment from my business and this past year a fair amount of Klipsch gear. You can also use EBay to drive sales to a personal site if you have one. You have your items listed and people can google what you are selling and find your site through that and it is cheap advertisement to a huge audience. I don't have a web site but I do sell the same things on Craigslist and probably half my buyers there came from EBay listings. It is generally understood if you state on your EBay listing that have your item listed locally and listing subject to end at any time people know to check for the same listing "title" on Craigslist and then you don't pay the fee. Crites has a big presence there and you know there is a fee mark it up to compensate and still arrive at the profit you want. I don't worry to much about the EBay commission because I have sold more things there by far than any where else and I did not have to open a physical store to do it.

    KP-301 II

    I play my music out in the shop due to space, WAF and the volumes I like to play at sometimes. It is rare that my wife has anything good to say about "noise" that invades her house space from the shop. She commented on how nice the 301 II's sounded. I bought these primarily for a guy who is setting up portable sound systems for fledgling bands to use. He does not know I have them and he may never get to hear them either. When I have people over to buy speakers they see the Industrial Pro La Scalas and I tell them you get to hear them AFTER you make up your mind on the speakers you came to see. I the 301's will also be in that category. Why did you get rid of them?
  19. Pictures later today. I bought a pair of KP-301 II's and KP-115 subs yesterday so new looking it was spooky. Brought them home and had a listen and wow. Recapped the crossovers in the 301 II's and these are clearly better than the 301's I have. They sound good enough that I am thinking do I keep the La Scala Pro's for the shop or these. The La Scalas have better punch but the 301's have better definition of a wider range of instruments and seem to have better stereo separation in my listening environment. Oh and bass to if I want it but nothing floor pounding deep but better than the La Scalas for sure.
  20. I like those cool Molybdenum Disulfide impregnated Delrin plug bodies. They make it all worth while.
  21. Yesterday I bought what was supposed to be a pair of KP-201's. What they really are I don't know. Inside on the mid horns though was a pair of soldered lug K-55V's. Now researching these led to discussions on K-55M vs K-55V and K-55V soldered lug drivers and how some (K-55M) would sound to bright on, you guessed it, AL-3 crossovers. Different behavior on A and AA crossovers. All things being equal with a pair of La Scalas the AL-3 were brighter than the AA's were with a K-55M driver but I liked the highs the K-55M brought to things like cymbals on this setup. The K-55M on the AA crossover was more muted on mid and high range but sounded better with blues and old pipe organ music. So add to the mix matching the driver to the crossover. Apparently K-55 whatevers and crossovers are not mix and match. For the first time I had newly recapped crossovers and a pair of La Scalas to play with at the same time and I am finding out the mid drivers need to be matched to them to complete the effort.
  22. There is a study quoted often out there where a guy used "high end" capacitors which cost up to four and five hundred each. 10% tolerance for many of these jewels and I figure it was tuning sound by inducing distortion for lack of a better word that the end user preferred over stock sound. I tend towards wanting to hear exactly what I would hear at a concert and I know their amps do not use these fancy costly designer caps. I am happy with what I have used and that is what counts and it did not break the bank. "I have been a Ham for nearly 37 years, so not into hocus pocus. Honestly, I think a lot of the differences people hear in Caps comes from replacing bad old caps, with new Poly ones. I have re capped many vintage speakers, using decent quality bipolar electrolytic capacitors, with excellent results." THAT is the best viewpoint and if you are well pleased with the result this is good and you saved money doing it. I like the polys and have no problem finding any value I need and from all I read they have a longer life than I figure I have left and there is always a noticeable improvement over the old stuff.
  23. I was referring to the lust for more bigger better different etc not components. Components can be a slippery slope too if you start going for those fancy hand rolled capacitors with mink oil and beeswax between Platinum and Gold foil and pure oxygen free stabilized Silver leads.
