I could've posted this over at the klipsch forum, but those guys are kinda stiff.

Anyway, I pulled the woofer of my Heresy IIs and found this big hunk of foam semi-rolled inside of the cabinet.

Should I replace this with new foam, use acousta stuff, or something else?  I already plan on getting some no rez for the cabinet.

If you are going to line it with No Rez then I'd toss the thin foam sheet. You can always use Acousta Stuff or fiberglass insolation in addition to the No Rez as needed.

Yes, toss that, line the cab with No-Rez, then Acousta-Stuff according to the guideline, which if memory serves me is .5 lb per ft^3 (someone correct me if I'm wrong).
