Woof, No Dog. This Bose L1 PRO Series Sub1 Portable Bass Module is a sleek, portable subwoofer designed to bring the bass to the surface for your event, party, or venue space. This unit can combine with nearly any PA system, and even delivers low-end performance down to 40 Hz.

S1 Pro Compatible. You can add this subwoofer to the Bose S1 Pro or S1 Pro+ with the separately available Sub1/Sub2 Adjustable Speaker Pole to make the L1 into a micro-PA. The speaker pole attaches to the integrated M20 threaded input located on the side of the subwoofer.

Stack ’Em High. Stacking two Sub1’s on their sides will enable cardioid mode, which helps your bass levels reach further without compromising sound levels or dealing with annoying feedback.

RaceTrack Design. The Sub1 sports a 13×7″ RaceTrack woofer that is designed a bit different than your standard woofer. The integrated Sub1 woofer is skinnier and less rounded, nearly oval shaped, and enables the bass module to be more portable a save more space.
