Corner-Specific Design (4-Pack) — Acoustic Corner Panels (9.4 × 4.7 × 4.7 inches); serves as a low-frequency absorber for use in recording studios, homes, and theaters.

Bass traps don’t always have to be massive—this compact 4-pack of sound-absorbing corner blocks is the perfect proof. Each block measures just 9.4 inches in length, 4.7 inches in width, and 4.7 inches in height, featuring a miniature triangular prism shape. Crafted from high-density acoustic foam (density ≥ 30 kg/m³), they come in a classic two-tone black and gray color scheme. Despite their small size, their exceptionally high density and precisely engineered right-angle structure allow them to effectively absorb low-frequency standing waves within the 80 Hz–300 Hz range. They are particularly well-suited for small vocal booths, near-field monitoring environments in home offices, or apartment-based home theaters where space is at a premium. Sold in packs of four, these blocks can be easily mounted in wall corners beneath a desk, within the gaps between bookshelves and walls, or in the four floor-level corners of a room. Once installed, low frequencies become tight and articulate—rather than muddy—while mid-to-high frequency details are allowed to shine through. This set is the ideal choice for users who wish to achieve effective acoustic treatment without having large, bulky acoustic modules take up valuable space.
