Auralex?s new SonoLite Bass Trap is a 3 in. thick, 2 ft. x 2 ft. fabric-wrapped absorption panel that provides excellent low-frequency control in either a horizontal or vertical orientation where walls or walls and ceilings meet. The core of each panel is made of Auralex?s Studio foam Pro acoustical foam. The panel is then carefully wrapped in a velour fabric to add a stylish appeal to accent any decor.
