CustomSound™ CSIR SUB In-Room Subwoofer

This In-Room Subwoofer offers several elegant and highly versatile solutions. Measuring a mere 15 3⁄4” x 15 3⁄4” x 4 3⁄4”, the CSIR SUB can disappear into the décor of any room, but its stylish design is a feature in and of itself.

    -On-Wall with supplied mounting bracket
    -On-Floor with supplied base
    -Laid on its back for under or behind furniture

CustomSound™ CSIR SUB can be placed in 3 distinct ways. It can be mounted on a narrow, low profile plinth and placed upright. It can also be set on its back allowing it to be tucked out of the way, behind or under furniture. It comes with a mounting bracket, enabling the subwoofer to be wall mounted to maximize floor space.

The 10“, high performance shallow driver offers deep and resonant bass well beyond its modest size.
