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



I agree with you that listeners tend to be biased to favor the “improvement” they invested in and may go overboard in a particular direction.  You rarely hear someone say that a particular tweak made the sound worse when any such change should have a fair chance at being for worse.  
When it comes to vibration damping, I’ve experienced where some additional damping was an improvement, but more than that sounds bad; it is NOT the case that more of something good is always better.  I heard a demonstration by a representative from Symposium who put a vibration damping shelf under a CD player and it improved the sound (everyone in attendance agreed).  The next level up in their product line slightly improved the sound.  But, the flagship shelf made the sound too dry and unpleasant; even the Symposium guy agreed the sound got worse.  How could better damping worsen the sound?  I don’t know, but I heard it.

If you found the CW IVs to be bright, hard to listen to, and basically fatiguing after 20 minutes why did you buy them in the first place? 

When first purchased, I listening to them in a prepared showroom .They were in my price range and I liked  the sound. I didn't have hours to spend listening and comparing. And not all music made me yawn. I listen to mostly  rock and roll 60s to 70s and 80s  100pct CD's  I found that better quality recordings were amazing and ok ones  weren't. but that's not the point Trying to make your system sound better is what we do, part of the hobby. My earlier tread in the beginning of this post, lists my changes in equipment and where I am today. I'm very happy with my system BUT always looking to improve it 

 I find non damped horns unlistenable, particularly the metal / aluminum/ plastic type. Most wooden horns I have heard, do not have these issues.  Been damping for 55 years, and there is " a sound " to the ringing / vibration to most horns. My clients have always appreciated the " improvements ". Enjoy, MrD

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.
