I have a few pieces of room treatment available for local pick-up in Chicago. I will not ship. Grab everything for just $50. SOLD!!!
Here's what I have:
1) Corner Bass Absorbers (8pk) 12x12x24 (CHARCOAL).

ECOMMENDED FOR: All room sizes with bass problems. Low frequency sound waves are long and very strong, so they are hard to stop. Corner Bass Absorbers will solve that bass problem that accumulates in the corners of the room with their amazing low end absorption qualities. A 4 pack is suggested for one 4 sided room, but if bass problems are really bad, we recommend the use of Corner Bass Absorbers in ALL corners of the room. Also, Corner Bass Absorbers are great for all around sound absorption.
2) 3" Wedge Foam (10pk) 12x48x3 (CHARCOAL)

RECOMMENDED FOR: Any size area. A great all-around sound absorber, with similar qualities to the 4" Wedge Foam. (Has even better qualities when used in conjunction with Corner Bass Absorbers.)
All pieces were used and then removed, but can still be used again.
