After installing large-area acoustic panels on the walls, untreated gaps often remain in the corners, allowing sound reflections to persist. This 4-piece set of corner-edge acoustic foam panels serves as the perfect supplementary solution to complete your acoustic treatment setup. Each panel measures 12×7×7 inches and is shaped like a right-angle triangular prism. Constructed from medium-density polyurethane foam (approx. 20 kg/m³), the panels feature a smooth, flat surface—devoid of pyramid or wedge-shaped textures—to ensure a flush, seamless fit against corner edges. You can install them in the seams between your existing wall-mounted acoustic panels and the corners, or use them independently as compact corner bass traps. Sold in packs of four, this set provides enough coverage to treat approximately 4 feet of corner length. Whether for a studio control room, the side walls of a home theater, or the back wall of a live-streaming studio, these compact foam blocks provide the perfect acoustic finishing touch, ensuring comprehensive sound absorption and enhancing the aesthetic appeal of the entire room.
