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

Most of the horns I like don’t necessarily require additional damping, including those made of metal or resin or plastic.  I like these horns because they were made right from the start.  But, it doesn’t hurt to try damping if it is reversible.  

@larryi , I am extremely sensitive to these nasties I speak of. I am interested to learn about what you have heard, that were made right. My best, MrD.

I am a fan of the vast array of horns made by Yoshimura Laboratories (YL) when coupled to their compression drivers.  They made metal horns, wood horns and some kind of resin; the horns come in all sorts of shapes and sizes, including horns almost the size of Western Electric 15A horns.  But regardless of shape and size and configuration of the throat, they are consistently free of gross horn coloration—not nasal sounding nor shouty—and they sound smooth and relaxed (no sharp peaks).

I also like a number of Western Electric horns and compression drivers.  Some that sound good to me, like the 15A, are not very practical, but horns like the 32A, are nice sounding compact horns.  I also like Western Electric compression drivers and the currently manufactured replicas by G.I.P. Laboratories.

My own horns are Western Electric 12025 sectoral horns driven by Western Electric 713b drivers.  Those drivers are very hard to find in matched pairs.  My horns are metallic, but I have left them untreated.  They are relatively compact but they are very heavy and the thick metal does not ring much.

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.
