ProPanel™ Corner Traps are 2″ thick, 2’x4′ (M224), fabric-wrapped, fiberglass bass traps, cut to fit smoothly within a standard 90° corner. They are an ideal corner treatment solution when increased low-frequency absorption is needed. Use the ProPanel™ Corner Traps in combination with B222 ProPanels™ and B224 ProPanels™ for a complete room treatment solution. For additional low-frequency absorption performance, we recommend pairing the M224 with our DST-LENRD™ Bass Trap.

Auralex Application Specialists are always available to assist you with any questions you may have regarding the specification, selection, or implementation of any ProPanel™ product.
