Auralex Studiofoam Pyramid-24 (Charcoal Grey, 12-Pack)

The 12-pack of Studiofoam Pyramid-24 from Auralex contains 2" thick, 2 x 4' acoustic foam panels that can treat small to medium-sized areas including isolation booths, studios, rehearsal rooms (any instrument except drums), and home theaters. The tiles effectively kill standing waves and flutter echoes, and when used in conjunction with LENRD or Venus Bass Traps, or Sunburst Broadband Absorbers, they can effectively tame the full acoustic bandwidth in virtually any environment.
