Auralex CornerFill Cube 1x1x1 Foot Foam (Purple, 2 Pack)

CornerFill Cubes are a terrific way to finish out trihedral corners where three LENRD Bass Traps come together. Great for gyms and larger rooms. Even without LENRDs, CornerFill Cubes offer excellent bass absorption and can look really cool, especially with other Auralex treatments butting up to them.
