The Bose B2 Bass Module contains two 10-inch woofers and is the option that delivers the most low-frequency output for L1 system users. The B2 is designed for L1 users who need more powerful bass for larger audiences.

A switch on the rear panel offers the flexibility of three output levels, depending on the application at hand. The L1 system senses the setting chosen on the B2 and equalizes the signal being sent for optimized speaker performance. The normal setting is ideal for bass guitar, or when miking a kick drum. A higher setting is designed for DJ and music playback applications. The lower setting works well for acoustic guitar and vocals.

Interlocking end caps allow two B2 bass modules to be stacked on top of one another. An included slip cover protects the module from dings and scratches during transport.
