Use our AP3500 Acoustic Panel to reduce acoustic distortion in listening areas such as recording studios, control rooms, and home theaters. When mounted to a room's hard surfaces, the panel absorbs sound to help defeat reflections, flutter echo, and comb filtering. Hardened edges retain the square shape to prevent drooping or drifting out of place. To comply with building safety codes, it is constructed of burn-resistant material with a Class A fire rating. Mounting hardware is included for ease of secure installation.
