  1. It is easy to imagine that our 40 or 50 year old Cornwalls vary in their condition. My 54 and 55 year old pairs both benefitted I think... one pair came with thin strips of Dynamat trimmed to fit and the other I installed the 1/8" thick gasket tape. Both backs compress to fit flush to the sides. There is a nice tight feel to the cabinet back. I had the backs off dozens of times as I've played with alternate horns and crossover setups. Some kind of finish washer might be a good idea as it seems the screws like to dig a bit deeper into the panel. It would be interesting to give it a knock test on the back before and after you apply the tape and install the back.
  2. I would consider a humming and vibrating power transformer defective. Plates are loose or something inside. Sounds like your satisfied. This is what is inside my computers at home: Acousti Products - AcoustiPack™ Soundproofing Materials There is a heat insulating quality to this material so I'd be careful. For speakers I've used No Rez from GR Research: No Rez 24” x 27” (4 pack) | GR-Research Funny thing, in my situation I was happiest using the expensive throw pillows from the couch. "When are we getting those back, Dad?" Uh... you're not. heh heh
  3. It's been a few years but I like the builds from these folks: Silent PC | Quiet PCs The parts they use were always top notch and their price is less than what I'd pay for the components even at discount. PLUS, they do all the work for me and add a warranty. Very nice build quality and they are QUIET which is very important to me... I hate the sound of pc fans!
  4. I just flip it over every 40 years just in case.
  5. Use gasket tape. https://www.parts-express.com/Speaker-Gasketing-Tape-1-8-x-1-2-x-50-ft.-Roll-260-542
  6. For the woofer I first tried the Crites cast CW1526C, then k33's from my La Scalas then the Eminence Kappa-15C. The 15C won as far as my ears were concerned as they seemed the most even and the best upper bass. The K33's were fine but just a little weaker at the top and the Crites seemed a bit heavy on the lower bass but that might have been in a range that I already get a bit of a peak. For bass bins to sound THIS good and for only 400 bucks is simply amazing to me! This is some pretty good BANG for buck!
  7. Yep... funny thing when I bought my La Scala's the seller collected organs and wanted only the organ and the amplifiers. He didn't want the speakers! I also removed the attenuators that were installed on the factory networks that were on larger boards than usual. The attenuators were cranked way down so the tweeter and mids had hardly been used over the 35 years they sat in a choir loft. The amps were installed inside the the top part of the cabinet with a newspaper metal plate between the amp and the cabinet. I looked to see but there was no date on the portion of the plate that was there... kind of wondered if it was from the local Hope AR newspaper. Really nice thing about these is that the top of the speaker cabinet can be unscrewed and removed for easy access to everything. Seemed obvious that Klipsch had done some custom construction for the organ company.
  8. I assume you might wonder if it thins out as it gets to a lower volume which is something I've experienced but NOT here! Listening at low volume... 60, 55, even 50 dB at my seat the image is all still there with full life and energy. Amps play a role with that too as sometimes we get amps that don't do as well with high efficiency speakers at lower volumes.
  9. SO here is the hardware installed - Network: Dean's Aletheia Audio Super AA networks w/ OIMP V-Caps Tweeter: Beyma CP25 Mid: BMS 4592ND-MID Drivers Mid Horn: Fastlane Audio Eliptrac 400 Horns Bass: Eminence Kappa-15C I'm considering having a tweeter shootout. This seems mostly a flavor thing... the sizzle on your steak... the Beyma does a beautiful job (to my taste) with cymbols and trumpet highs. It sounds so natural and just the right tone but maybe it has a bit more distortion? I have an attenuator from ALK so I can knock down the tweeters that are a bit too efficient. Here is my list so far I will try out: K-77 Crites CT-125 B&C DE-10 with stock horn (think I bought these from Claude way back) B&C DE-120 with Fastrac horn
  10. It is crazy that it has taken me so long to finally get these built and installed in my room! I started cutting wood for this over 7 years ago... finally completed over a year ago only to sit in the garage. A couple of fellow audio nuts helped me carry these upstairs and also move the La Scalas out to the garage for new veneer or Duratex. WHY did I wait so long?! This sounds awesome! Smoothed out the bass and seems to add another octave down. It is so much smoother and clearer on the bottom end! I thought the dispersion would be a bit narrow having these up on end like this. The smallest adjustment of toe-in seemed to have a big effect. Quite a bit of listening and adjusting and all of a sudden they just lit up the room! It was actually that dramatic. It nailed it not only for the sweet spot (what I mainly care about) but most of the room. There was a bit of "chesty" resonance maybe around the lower registers of the male voice. It was suggested to drop a pillow at the end of the horn and that resonance was gone. I added some NoRez padding from GR Research... it helped a little but not nearly as much so I put the pillows back. The family wants the pillows back on the couch but I don't think that will happen too soon. The mid horn and tweeter assembly is sitting on a brace/shelf that is the exact height of where they were sitting on top of the La Scalas with a slight tilt down. Yeah, I'm pretty happy! Oh and for all the help I owe thanks to @paul79, his friend Jered, and certainly @ClaudeJ1!
  11. It is a lot of fun when things come together! What's amazing is that you can always seem to find even more improvements but there is nothing wrong with sitting back and enjoying the moment!
  12. I have similar… 1 tube trap in each corner, 1 at each first side reflection point, and 1 center of front wall pulled out a bit. I’m considering more diffusion at the front wall. I have some absorption on the ceiling due to the cathedral ceiling causing some issue. I’m glad I’m not buying those new today! They do a nice job but painful for the wallet.
  13. Congratulations! Corners weren't a choice for me as far as speaker placement. I played with speaker placement for a long time trying to get the peaks and nulls on the low end to even out as much as possible. I have absorption on the sides but much preferred diffusion to absorption on the front (between speakers). Absorption deadened the sound with just a single much less a couple of 2"x2'x4' panels on the wall. I now actually have a single tube trap with diffusion panel pointed forward and placed in the center somewhat even with the rear of the speakers. I can pull it forward and back to "focus" the sound stage somewhat... pretty cool results.
  14. Not familiar with the Yamaha you mentioned... is that model correct? I've had a lot of fun with the CR-2040 and Marantz 2330... if going vintage integrated the Yamaha CA-2010 is amazing. The 2040 has a really nice low end that helps the La Scalas a bit. I guess it kind of depends on your goals... I listened to vintage receivers usually while doing other things with Cornwalls or Heresy's (garage, bedroom). I'm not really answering your question but was curious about the Yamaha. Honestly, I'd like you to try them all yourself and report back with your comparison. Are your LaScalas stock? Have fun!
  15. Be careful with the tube amp... I know that some require a speaker load at all times while powered on. Might check to see if that is the case for yours.
