2-Inch studio foam wedges are our most popular studio foam 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 lend bass Traps, Venus bass Traps or Sunburst broadband absorbers, can effectively tame the full frequency bandwidth in virtually any room. 2-Inch acoustic studio foam 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.
