Thanks again LDQ, I went there and picked up nine pannels today (for $50.) they didnt have O-C in stock, but they had the same stuff made by another company.
Ethan, if my math is right it looks like a paid 64 cents per sq/ft for 2 inch think stuff. Much less than auralex (too bad I cant take that crap back!).
Welp, about to leave work to pick up some fabric and a backer board. I think I am going to double up the fiberglass and make 2 4'X4' pannels 4 inches thick backed by either thin plywood, or a sheet of panneling or something. Hopefully this will help my bass issue more than the auralex.
