Bose B1 Bass Module - Powered Subwoofer

The Bose B1 Bass Module is a subwoofer designed to be a compact and portable bass enhancing solution and primarily intended for use with the company's L1 Systems.

Instead of a big woofer, it sports two 5.25" woofers that prioritize bass clarity over excessive thump.

Also, it utilizes Speakon connectors that complements the Boss L1 system nicely.

Clear and clean sounding bass is what the Boss B1 Bass Module is all about. Many appreciate how it complements the Bose L1 system nicely, be it for home entertainment use and for small to medium size venues. It's portability is also commended often, with some finding themselves surprised at how full sounding the L1 system is when equipped with the B1 Bass Module.

With its smaller 5.25" woofers, don't expect much thump from it. So if you are into dance, electronic music or any style with deep bass requirements then this is not a good fit.

This is perfect for owners of the Bose L1 system who are looking for a way to enhance their bass frequencies without adding to much bulk and weight to the setup.
