The Auralex SonoLite™ panel offers great absorption performance in a lightweight and slim 1? profile. At the core of each panel is our high performance Studiofoam® Pro, allowing the SonoLite wall panel to achieve an NRC rating of 0.80. Offered in two attractive velour fabric color options, black and tan, they are designed to mount to flat walls and ceilings. For added low frequency control, consider using SonoLite Bass Traps in the corners of your room.
