Bose Sub2 Powered Bass Module - subwoofer - for PA system

A powered, portable bass module, the Bose Sub2 Subwoofer combines with virtually any portable PA and delivers low-end performance down to 37 Hz. Its unique 10-inch x 18-inch high-excursion neodymium RaceTrack driver allows for an ultra-slim enclosure, delivering the performance that rivals a traditional 15-inch woofer without the cumbersome size, freeing up room in your vehicle and on the stage. You can stack multiple Sub2 subwoofers for even more low-end - or unleash Cardioid Mode for directional bass. With a Sub2, you get a subwoofer that easily fits onstage - and effortlessly fills up the dance floor.
