Bose SubMatch Cable for Sub1/Sub2 & L1 Pro32

The Bose 857172-0110 is a SubMatch Cable engineered to link a Sub1 or Sub2 powered bass module directly to a Bose L1 Pro32 portable line array. The single 12-gauge run carries both power and the audio signal, so you can leave extra extension cords and XLR lines in the case. A spring-loaded locking collar twists firmly into place, giving touring musicians and mobile DJs the confidence that the connection will stay secure throughout load-in, performance, and teardown.

Once connected, the cable allows the L1 Pro32 to recognize the attached sub and automatically set the crossover and EQ. This built-in calibration delivers tight, balanced low frequencies without manual adjustments, whether you are reinforcing speech in a house of worship, providing background music at a corporate event, or pushing dance tracks at a club.

The design also makes it easy to expand. If your set list or venue calls for extra low-end punch, you can daisy-chain a second Sub1 or Sub2 using the same SubMatch link. The additional module receives both power and signal, keeping the stage clean and the setup straightforward.
