Based on the popular SonoFlat studiofoam absorption panel, each Auralex SonoFlat Grid panel measures 2'x2'x2" and is composed of nine 8"x8" beveled squares. Made from Auralex's proprietary and world-renowned StudioFoam, these panels offer the impressive mid- and high-frequency absorption the original SonoFlat panels are known for, as well as an elegant look that makes them a great addition to any studio, home theater or listening room. The panels install easily and can be arranged in a multitude of attractive patterns - even layered.

The panels are available in three popular colors and are made from Auralex’s long-lasting, melamine-free formula, which won’t crumble with age.
