Stereo Integrity BM-11 v3 11" D2 Subwoofer | 500W RMS | 3" Mounting Depth

The highly acclaimed Stereo Integrity BM-11 v3 is back—redefining what's possible from a shallow-mount subwoofer. This 11" Dual 2 Ohm subwoofer delivers rich, dynamic bass with a shallow 3.0" mounting depth, making it perfect for space-limited installs without compromising sound quality.

With a newly tooled cast aluminum frame, custom S-surround, and glossy carbon fiber flat cone, the BM-11 v3 combines elegant design with high-performance engineering. Its advanced dual-gap, 10-piece neodymium motor structure drives a 3" 8-layer copper voice coil with precision, producing accurate, distortion-free bass with 14mm one-way Xmax.

Built for Performance and Precision

At just 16 lbs, this subwoofer packs a punch without adding bulk. Featuring XBL² motor topology, it offers lower distortion, reduced inductance, and a wider frequency bandwidth than most shallow subs on the market. The BM-11's carefully tuned balance between motor strength and moving mass ensures fast transient response and clean output at any volume.
