  1. I got a used HK AVR 1510 for him from Facebook marketplace. It shows it is rated for 75 watts per channel but the thing was probably only 5 or 6 pounds. It was really, really light. My brother's old Sansui receiver from the 80s has to weigh 60 pounds. I know, class A vs. class D. I'll check the settings when I visit him next. Klipschguy, I have a question. Why do you prefer the 'industrial' caps versus 'audiophile' caps? I dabble in crossover design and DIY speakers and I have a lot to learn. I would love to hear what you've discovered by using different caps. I will admit that the way speakers work in general is almost like magic. I don't understand how or why they work but there is something so special about great sounding speakers. Add to that your source and amplification as well. It's a team effort. You play the right music on a great set-up and it can lift your spirits, help you relax, get you crunk, or put you 'in the mood'. It is literally a disc shaped thing flapping back and forth in a wooden box and it somehow changes the way your brain works. I don't know what else to call that but magic. I'm hoping I can restore some of that magic for Tommy and his old Cornwalls. Thank you all for your help with this.
  2. Thank you for all of that info. My father-in-law has quite a few stories about these speakers. Sadly most of them would probably qualify as abuse stories. I'm no audiophile but to me it sounds like the speakers are starving for power. There is almost no bass response at all. I used a little bluetooth tube amp and ran some modern 'music' from Youtube and turned the treble down and the bass all the way up and they would shake the floor with the amp I made. Running them on just the HK receiver there is almost no detectable bass. The speakers are very close together and about 8" from the wall. Certainly not what I would call an ideal set-up. I am going to see if he will allow me to do a crossover swap with modern parts and see what that gets us. I figure that as long as I don't use Mundorf caps I can get away with about $35 for both crossovers. Someone from the help desk emailed me a link to the Cornwall crossover designs here.
  3. Hello. My name is Brian Raulerson and I'm hoping to get some helpful info for my father-in-law. He retired recently from the Florida Theatre as the sound technician. He has owned these speakers for quite a while now but hasn't been using them. I gave him a Harmon Kardon digital receiver to take advantage of them to go with the TV I got for him. Based on what I've read on the forum here the speakers are Raw Birch Cornwalls built in 1979. As far as I know there has been no maintenance done to these speakers so I would assume that the caps are shot. I would like some advice on a few things regarding these speakers. 1) Should I replace the caps regardless of condition? 2) The speaker cabinets appear to be painted. Should I refinish them with stain/poly? 3) The class D amp doesn't seem to satisfy these speakers. Any recommendations as far as amps go? I built a 200 wpc amp using ICE power boards (made by Bang and Olufsen). Would that work or do these prefer analog power? Thanks for any information you can give. P.S. Sorry for hijacking that other post!
  4. Brand new here (as in I signed up today) and hate to hijack a topic but I'm trying to work on my father-in-law's Cornwalls and his serial number is very similar to the one posted here. Can you tell me anything about them and maybe some tips. They appear to be painted but I was hoping he would let me strip them down and have the natural wood grain show (if they have that). I also gave him an HK receiver to power them and he gets plenty of mids and highs but I don't think the little digital surround sound receiver can feed them. Thank you in advance for your help.
