: Unique RaceTrack woofers integrated in the Bose Sub1 and Sub2 modular subwoofers deliver powerful bass, have an optimized center of gravity, and save a lot of space. This slim design means you get the full impact of a conventional subwoofer without the cumbersome size, freeing up room in your vehicle and on the stage, and making every carry in between — home to car, vehicle to venue — much easier. <ref>[https://pro.bose.com/en_us/solutions/portable/l1-pro-family/sub1-sub2.html RaceTrack Woofer] on pro.bose.com</ref>

{{Template:Sub2 with Sub1}}


Stack two Sub1 or Sub2 subwoofers in Cardioid Mode for focused, directional performance with reduced rear-firing bass energy (-10 dB SPL). This steers the bass out front, and reduces feedback. This is particularly useful when you have resonant instruments on the stage (e.g., kick drum, upright bass).

Sub1 and Sub2 have extruded aluminum heat sinks mounted to the backside of the I/O panel. This pulls heat out of the electronics and transfers some to the air moving through the acoustic volume of the sub and helps to cool.<ref>[https://www.facebook.com/groups/BoseL1/permalink/10159635582172446/?comment_id=10159637158957446 Bose Professional]</ref>
