Auralex Acoustics 4 inch Pyramid StudioFoam Sound Absorption Panels 2x4 ft. (Charcoal Pack of 6) 4PYR24CHA

Studiofoam Pyramid is one of the most popular sound-absorption materials on the market. These high-quality acoustic foam panels are perfect to treat small to medium-sized areas including isolation booths, control rooms, and sound studios. They can effectively tame the full frequency bandwidth in virtually any acoustic environment when used in conjunction with Auralex's LENRD Bass Traps, Venus Bass Traps, or Sunburst Broadband Absorbers. Studiofoam Pyramid panels are specifically designed to alleviate slap and flutter echo, the two most common problems in rooms not specifically designed for music recording or performance. They are a wonderful solution for spaces that demand proper sound control without complete acoustic absorption and small rooms with high SPLs (Sound Pressure Levels). It features:

• 6 individual panels (measuring 2 ft. x 4 ft. each and 4 inches thick).
