Bose Sub 2 Powered bass

The Bose SUB2 Powered bass is an amplified subwoofer.

A portable powered bass module, the Sub2 subwoofer complements virtually any portable sound system, with a frequency response down to 35Hz. Its unique RaceTrack high excursion 10" × 18" neodymium magnet transducer reduces cabinet depth and delivers performance comparable to a traditional 15" bass module without the associated clutter, saving space in your vehicle and on stage. Compared to the Sub1 subwoofer, the Sub2 is more powerful and easily complements the Bose L1Pro32 system with a single SubMatch cable. You can layer multiple Sub2 subwoofers for even more bass, or use cardioid mode, making bass directional. With a Sub2, you've got a subwoofer that fits easily on stage and effortlessly brings sound to the dance floor.
