The Bose B1 Bass Module works seamlessly with the Personalized Amplification System family of products 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. Connects to the PS1 power stand with a single cable.
