Bose Professional L1 PRO Series Sub2 Portable Bass Module

The Bose Sub2 is a powered portable bass module designed for the Bose L1 Pro series line array systems. Featuring a larger 10″ × 18″ high-excursion neodymium RaceTrack driver, the Sub2 delivers deeper, more powerful bass down to 37 Hz with higher output than the Sub1, all in a slim, easy-to-carry enclosure.

It connects seamlessly with the L1 Pro32 using a single SubMatch cable that carries both audio and power. It can also be paired with the L1 Pro8 or L1 Pro16 for extended low-frequency reinforcement. Multiple Sub2 units can be stacked to increase bass performance for larger venues.
