Constructed with sturdy 3/4" plywood framing and filled with dense R23 Rockwool insulation, these traps are engineered to reduce bass buildup, ringing, and room mode issues. Each trap is hand-wrapped in premium Acoustimac acoustically transparent fabric and finished with a black cotton backing fabric.
