klipsch cornwall iv upgraded crossovers

Sorry to chime in late wasn't able to post because my address wasn't on file. But I dampen my IV's a year ago. I used Dynamat 1/4 inch tape .The sound  improvement was clear and very obvious Warmer less squawking much easier to listen to I used to get tired of listening and yawning after 20 mins. The first thing I noticed, was I could listen for an hour without squirming. I stopped yawning and enjoyed favorite cuts with new enthusiasm. Damping involves 35$ and 2 hours of work .It's easy to do and I highly recommend it. And best of all if you don't like, it takes 20 mins. to reverse. I've seen the negativity on some post a lot goes in to good sound. Equipment decent wires room size and acoustics. But  above all quality of recordings.  Naysayers can say what they want but my IV's sound like Six's now.

I looked into the upgraded crossovers . There's a store on ebay with good reviews. The problem was you had to take your crossovers out and ship them to him. He also had a long turnaround do to backlog of work. If I could have bought them outright, I would have taken a chance. But without the original  crossovers to go back to NO.

Perkadin,

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
