Auralex 2" Studiofoam Wedges Burgundy

Use 'em to treat small- to medium-sized areas including vocal booths, control rooms, and sound studios. They effectively kill standing waves and flutter echoes and, when used in conjunction with LENRD or Venus Bass Traps or Sunburst Broadband Absorbers, can tame the full frequency bandwidth in virtually any room. 2" acoustic Studiofoam is the workhorse of the industry and your safest bet if you're tuning your room without the help of a professional acoustician.
