The Bose Sub1 is a compact powered portable bass module designed to extend the low-frequency performance of portable PA systems. Featuring a unique 7" × 13" high-excursion RaceTrack neodymium driver powered by a Class-D amplifier, the Sub1 delivers deep, musical bass down to 40 Hz while maintaining an ultra-slim enclosure that's easy to transport. Designed to pair seamlessly with the Bose L1 Pro32 via single-cable SubMatch connectivity, it is also compatible with virtually any portable PA system through its balanced line inputs and outputs. Multiple Sub1 modules can be stacked for increased output or configured in Cardioid Mode to reduce rear-stage bass energy and improve on-stage clarity.
