The 2-pack of Studiofoam SonoMatt-24 from Auralex contains 2 x 4' acoustic foam panels cut in the industry standard "eggcrate" style, which allows them to function almost as well as 2" Studiofoam Wedges while providing a budget-friendly solution for the acoustically discerning user.

Due to the manufacturing process, the dimple pattern is not square to the edges of the panels so installing them side by side is not advised where visual consistency is of high importance. It is however a good choice for users who intend to cover the panels with acoustical cloth, or for low visibility applications such as equipment closets, computer rooms, backstage treatments, and broadcast facilities.
