Ideal for professional and residential settings, the tan SonoLite Bass Trap Panel from Auralex is an acoustical absorption panel with bass sound absorption coefficients of 0.55 at 125 Hz to 1.14 at 4000 Hz. The fabric-wrapped, 3" thick panel can be installed in either vertical or horizontal orientation on walls and ceilings. The panel is made from Studiofoam, which optimizes low-frequency sound and prevents bass build-up and cancellation. For added convenience, EZ-Stick Pro mounting tabs are included.
