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