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


Crites does not make a xover for the CW IV. And even if they did, xovers are not what they do well. First hand experience here.

@eoj4952 Contact Don through his website. He would probably be more than willing to share what he did, he's a good guy.
