Auralex Studiofoam Wedge-22 (Charcoal Grey, 12-Pack)

The 12-pack of the Studiofoam Wedge-22 from Auralex contains 2" thick, 2 x 2' acoustic panels that can be used primarily to treat small to medium-sized areas, including vocal booths, control rooms, and sound studios. The tiles effectively kill standing waves and flutter echoes, and when used alone, function as an overall absorber for any mid- to high-frequency issues.
