2″ Wedgefoam panels are fantastic in treating small to medium-sized areas including vocal booths, control rooms and studios. They effectively kill standing waves and flutter echoes and when used in conjunction with our StudioPro Bass Traps and Corner Traps, can effectively tame the full frequency bandwidth in virtually any room. 2″ Wedgefoam is quite simply your safest bet if you’re tuning your room yourself without the help of a professional acoustician.
