Sound Control - Easy on the Eyes and Wallet!

ASC SoundPlanks are the perfect companion to ASC TubeTraps for complete control of the acoustics in your room.  After the bass range is under control, the SoundPlanks further improve imaging and flutter echo without taking up any floor space.  Tall and relatively narrow panels provide distributed acoustics without taking the sonic "life" out of the space. Install approximately 16" on center near early reflection points for optimal results. For a dryer sound, install closer to 12" on center.
