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

It was good that pryso mentioned it. Yes, the basket. Google " woofer basket ", and you will see the baskets, naked. Hope you are of proper age, lol.

What do these baskets slip over the originals I think I know the old ones don't come off right 

Hey, a year later. I used sound deadening tape to sutile the sound of my Cornwall IVs. Look it up on You tube. Best thing  I ever did. Best speakers out there for under 10,000 There amazing. Every upgrade makes you WONDER They just get better.

Is there a link to what exactly Don Sachs did?

I did an Internet search and couldn't find anything.

Thx!
