The Bose B1 Bass Module is a passive low-frequency, portable speaker intended for use with the Bose L1 Line Array Systems. The speaker enhances the low-frequency response of the L1, adding depth and bass to musical instruments, DJ rigs and other sound reinforcement applications. The B1 may be connected to the base of the L1 system, or use the optional A1 amplifier to provide added power to a pair of B1 speakers.
