The Dark Gray SORBER S3 Baffle (33 x 22") from ClearSonic is designed to reduce the amount of reflected sound. It can be attached to the inside of ClearSonic panels or to any wall to reduce reflected sound and improve acoustics. The baffle's 22" width enables it to easily fit A3, A4, and A5 panel systems. The material works well with touch fasteners. The baffles can be attached to most flat surfaces.
