Shame Al K. is retired. He made me a Universal xover for my 82 Corns. & installed them outside the cabinets. He worked with me & I went with, Altec 511s w/ the 55v driver. Did the dynamat trick to the baskets & new gaskets all around, braced the front baffle & sides, but never did the brace to the rear panel. To me they’re outstanding. Also, I’ve been dealing with Don Sachs for sometime now & I also respect his opinion. Sorry I can’t help you out with who to go to. You can try the Klipsh forum, maybe someone there can help.
klipsch cornwall iv upgraded crossovers
I own a pair of cornwalls, amazing speakers they are paired with MC452 power and a MC 70 tube pre.I play cds only on a yamaha C2100. My question is I hear people talking about upgrades to the crossovers on the corns and softening the horns with sound tape . Do any of those changes work,one or the other and do they make it worthwhile. Would like input from anyone who has tried the upgrades and who they used
