Add bottom end to your Bose system.
The Bose B1 Bass Module works seamlessly with the L1 Model I PA System to deliver the low-frequency impact you want through 2 high-output, high-excursion 6-1/2" drivers. It produces deep, strong bass for keyboards, kick drum, bass guitar, and other instruments that play in the baritone/bass range. Light and compact, strong bass is yours without the bulk and weight of traditional subwoofers. It connects to the L1 Model I Power Stand (sold separately) with the included 5-foot B1 bass module 4-wire cable. It also comes with a carrying case.
