Sonomatt acoustic foam panels are cut in the industry standard eggcrate style absorbs almost as well as 2" Studiofoam Wedges. It may be the perfect choice for those who intend to cover their sound control materials with acoustical cloth. The perfect product for the budget-conscious, yet acoustically-discerning, customer. Due to the manufacturing process we use, Sonomatt's dimple pattern will not be square to the edges of the panels, so installing them side by side may not be advised from a visual consistency standpoint.
