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®, allowing the SonoLite™ wall panel to achieve an NRC rating of 0.80. Offered in 10 attractive velour fabric color options, 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. If you are looking for a full wall treatment set, have a look at the SonoLite™ Cloud Panel System above the listening/mix position to complete the whole room treatment package.
