Bose Bass Module Model B2 Subwoofer - Used
** This unit is used but it's great condition **
The Bose B2 bass module is a high-performance bass module designed for the Bose L1 Model 1S and Model II systems. It delivers the most low-frequency output for those L1 system users who require more powerful bass for larger audiences. It includes a rear-panel switch with three output settings, each of which is automatically sensed and equalized by the L1 system for optimized performance.
