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

Being a newbie, Reading the post I would think damping the cones. Just curiosity,  what and where is the metal woofer box. 

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!
