The IW-200 is an in-wall subwoofer with a sealed enclosure. The sub enclosure box mounts easily between 16in on-center wall studs, and its vibration-isolating outer foam layer virtually eliminates the risk of buzzing and wall rattling. Recommended for rooms up to 3,300 cubic feet in volume. Larger rooms can simply use multiple IW-200 subwoofers. Create deep, accurate bass without altering a room’s design. Easily mount between standard wall studs. Contains patented subwoofer technology. Blend into any room’s decor. Combine with the SolidDrive to create the ultimate “in-wall” home theater system.
