| Is 2" rigid Rockwool comparable to 2" O-W 705 for bass trap use?
Im curious about this due to the fact that, locally here, the rockwool is less than 1/2 the price of the 705.
I am told that this 2" thick rockwool is very rigid, and has an 8-pound density. Can I use this in the corners the same way as others are using 705....will it work as well? Of course, I'd want to use double layers, so as to have a 4" total thickness...right????
Many thanks in advance!
