I just located some 701 fiberglass for sound control. Cost- about $1.60 for a 2'x4'x1.5" piece. As far as I know, thats a great price. BUT: He'll only sell it in a pack of 30 . Way too much for my needs. Anyone around CLEVELAND (200 mile radius) want to split it with me? They also have the rigid tubes of figerglass- 10"- $2.54/L.F. and 14"- $3.35/L.F. (like an ASC Tube Trap) Easy to make your own traps and treatments. This is a great find for anyone in the area. I figure I can drive 100miles and you can drive 100 miles.
