BOSE SUB2 Active 1000w 10″x18″ Speaker Sub-Woofer for L1 Pro32 System
Compared to the Sub1 subwoofer, Sub2 is the more powerful subwoofer option for the Bose L1 Pro32 system, combining seamlessly via single-cable SubMatch connectivity. You can stack multiple Sub2 subwoofers for even more low end - or to unleash Cardioid Mode for directional bass.
