Auralex 4SF24CHA 4″ Studiofoam Wedge24 Charcoal

4″ Studiofoam Wedges are our most popular Studiofoam profile! Use them to treat small-to-medium-sized areas including vocal booths, control rooms and tracking studios. They effectively kill standing waves and flutter echoes and when used in conjunction with our LENRD Bass Traps, Venus Bass Traps or Sunburst Broadband Absorbers, can effectively tame the full frequency bandwidth in virtually any room. 2″ acoustic Studiofoam is quite simply the workhorse of the industry and is your safest bet if you’re tuning your room yourself without the help of a professional acoustician.
