We pulled out all the stops and have designed, and tooled, all critical components from the ground up. The BM mkIII has 28mm of total linear travel, a massive 10” diameter spider, 8 layer copper voice coil, proprietary two piece flat diaphragm, a shorting ring, and a 10 ring neodymium cluster magnet structure. We have shoved all of that technology into an incredibly compact package of only 3.5” deep. And it also requires only 0.5 cubic feet of sealed enclosure space to achieve optimum performance.

The BM mkIII is setting a new standard for sound quality subwoofers, both for shallow and regular depth. The BM mkIII has the ability to reproduce deep, high level bass, and at the same time totally disappear giving you the impression that your front speakers possess massive amounts of bass. Not being able to pin-point where the subwoofer is located at is exactly what a top notch sound quality subwoofer should do – and that’s exactly what the BM mkIII does.

If you are after the pinnacle of SQ with good output, this is it.
