  1. Try forgetting your six and reconnecting new. My son had a problem like this with a Marshall Wootan. Got where he thought it was blown up. Reinstalled and volume came back to normal.
  2. That is an imposing mid driver. Googled it to see Pringle’s, Amazon shows 499.00. Also calls it a subwoofer with 4” voice coil. Nothing is perfect. Nashville Plywood and Middle Tennessee Lumber May stock the 1” Baltic birch. 42.00 a sheet is very reasonable.
  3. Dave did the same for me. The LS II has a different tweeter. Same K-77 driver, wider horn. In fact Dave machined them while we sat and listened to music. Glad he did not pull out the ‘shine. Leaving his place in the dark was a bit challenging sober. When it gets dark there, it is really dark.
  4. You may need to ignore our feedback. We are the Dave A fan club.
  5. Same here have Dave’s Walnut horns and B&C DE-120 in La Scala II. No mods to crossover. Sounds much improved.
  6. I do not know the Duke. But used interfaces with MC33079 quad opps.. Surface mount package. Tried several replacements. None were an improvement. Most a step back. I would leave these alone. I doubt the TL084 is an upgrade. Crown designed these with sound quality in as a priority. After all these years a recapping might pay dividends.
  7. Yes, 3,000.00 should get a pair in excellent condition. With nice wood. The mods are nice. Rough painted cabinets put these in the sub 1,000 range for me. And your room is really too small. Cut out some 25” x 25” cardboard and place them on the floor. Pull out about a foot from the wall. Look how they dwarf the room. And see what listening distance works out as. I sit about 10’ from mine. Some feel they need to to 15 - 20’ away from you.
  8. Try the internet for the wool. Should be able to source some. Check some diy speaker supply websites.
  9. I think REW is incredible. Would love to try and align my LS ii. Need to make another donation to keep it running. Spent a month first sweeping the interface and evaluating issues. Then a couple amplifiers to see what they delivered. Found a 3 dB difference in one of my diy builds, plus distortion shift between channels. Never played music during that month. Back to listening now. I think I can spend a year diddling with the speakers. I might try the crossovers built into Pure Music. 64 bit filters with amplitude and time adjustments.

  11. Damn, Those do seem to be excellent. The ported bottom end may be the ticket. The port flares are a step up. Usually a port is a hole in the cabinet. Like the decision to front firing port. More flexibility in wall spacing. The price may be zooming up, but the competing new speakers are not getting cheaper either. The horn loaded ports sure look pretty. Would love to hack some on my Hiii.
  12. I dream over the top. How about two braces per side? Maybe closer together than thirds, say gaps of 35-30-35% of height to better contain the mid panel deflection and spread the resonance frequency? I have a giant roll of automotive double sided “tape” used to attach trim to cars. Sticks to paint and varnished surfaces. Grey rubber looking stuff. Do not laugh, used it to mount some LED lights under kitchen cabinets. A friend laughed when they saw my project. But they have been there over 16 years now. Never drooped or fell. Yet. I am sure it would work great to temporarily mount these braces. Plus not damage the finish of the LS ii.
  13. Off to Claude for measurements. Some more knowledgeable than me have said this is better than smooth. Definitely looks very nice.
