The Bose SubMatch Cable is the ideal cable for connecting the activeSub1 or Sub2 bass modules to the Bose L1 Pro systems. The cable is used for power and audio transmission, simplifies set-up and enables automatic calibration of the system’s crossover and EQ to achieve optimal sound quality.
Note: A SubMatch cable is included with every L1 Pro32 line array. It is used to carry power and audio from your L1 Pro32 to the Sub1 or Sub2 subwoofer. If you wish to connect a second Sub1 or Sub2 to your L1 Pro32 system, you simply need another SubMatch cable.
