A powered, portable bass module, the Sub2 subwoofer combines with virtually any portable PA and delivers low-end performance down to 37 Hz. Its unique 10 × 18-inch high-excursion neodymium RaceTrack driver allows for an ultra-slim enclosure, delivering performance that rivals traditional round drivers without the cumbersome size, freeing up room in your vehicle and on the stage. Compared to the Sub1 subwoofer, Sub2 is the more powerful subwoofer option for the Bose L1 Pro32 system, combining seamlessly via single-cable SubMatch connectivity. You can stack multiple Sub2 subwoofers for even more low end — or to unleash Cardioid Mode for directional bass. With a Sub2, you get a subwoofer that easily fits onstage — and effortlessly fills up the dance floor.
