XL Column Acoustic Wedge Foam Corner Blocks — High NRC Soundproofing for Studios & Home Theaters (12 Pack)

Very Good Quality High NRC. These XL column wedge blocks are made for corner installation — wall corners, ceiling corners and other junctions where reflections create unwanted echoes. They help reduce reverberation and improve sound clarity in studios, home theaters and similar rooms. For optimal acoustic performance, install them along the full height of the corner, covering from top to bottom. Care: remove dust occasionally with a vacuum.
