Clean Corner Coverage Without the Bulk
Most corner bass traps take up significant space and can dominate smaller rooms.
Our Low Profile Corner Acoustic Foam Panel was designed for customers who want a cleaner look while still treating room corners effectively.
The 3" × 3" × 24" profile fits directly into wall-to-wall corners and pairs naturally with pyramid, wedge, or flat acoustic foam panels installed on adjacent walls.
Perfect for:
Home studios
Gaming rooms
Streaming setups
Podcast rooms
Offices
Home theaters
Designed to Work With Your Existing Panels
This product is not intended to replace a full-size bass trap.
Instead, it acts as a corner treatment that complements your wall panels by providing additional absorption where sound reflections naturally concentrate.
Install pyramid or wedge panels on both walls and place the corner panel between them for a cleaner, more finished appearance.
Built From High-Density USA-Made Foam
Like all Sound Trap products, these panels are made using high-density U.S.-manufactured polyurethane foam and ship uncompressed to preserve the foam's cell structure and performance.
