Corner-Specific Design (4-Pack) — Curved corner acoustic foam; large dimensions (16.5 × 6.3 × 12 inches) specifically engineered for low-frequency absorption—perfect for use in recording studios and home theaters.

Low frequencies—particularly within the 80Hz–200Hz range—represent the most challenging aspect of acoustic treatment, and wall corners are precisely where low-frequency energy tends to accumulate most severely. This 4-piece set of curved corner acoustic foam panels was created specifically to address this issue. Each panel features a curved outer surface—rather than traditional sharp angles—and measures 16.5 inches in height, 6.3 inches in width, and 12 inches in depth. The internal material consists of high-density polyurethane foam (density: 28 kg/m³), treated with a specialized open-cell process optimized for low frequencies; this ensures that sound waves follow a longer, more tortuous path once they enter the foam, thereby converting low-frequency vibrations into thermal energy. The curved design also minimizes high-frequency diffraction effects, resulting in smoother sonic transitions. Sold in packs of four, these panels are recommended for installation in the room’s four vertical corners (where the walls meet the floor) to significantly reduce low-frequency “boominess,” allowing subwoofers and drum beats to sound cleaner and more impactful. Ideal for professional recording studios, home theaters, and Hi-Fi listening rooms.
