Sub1 Powered Bass Module combines with virtually any portable PA to deliver low end down to 40 Hz. When paired with the Bose L1 Pro32, Sub1 creates a more compact system and gives you bold bass from slim design that goes virtually anywhere. With a unique RaceTrack driver design, Sub1 offers powerful bass and an optimised centre of gravity. The driver’s shape allows the physical enclosure of Sub1 to be slimmer without compromising sound. This frees up room in your vehicle and on the stage, and makes every carry in between — home to car, vehicle to venue — much easier. Stack two Sub1 subwoofers for even more bass or to unleash Cardioid Mode for focused, directional performance that negates rear-firing bass energy, steers the bass to the front and reduces feedback. Sub1 pairs seamlessly with the L1 Pro32 via proprietary SubMatch connectivity to form a modular line array system that’s easy to pack, carry and set up. This single-cable connection makes setup so much easier. It allows the system’s crossover and EQ to automatically calibrate for optimal sound, and—because power and digital audio are passed through the SubMatch cable—you only need a single power socket. Just plug in your L1 Pro32 and you’re ready to go.
