Powerful Bass for Your Bose L1 System

The Bose B2 bass module is a high-performance flexible bass module purpose-built for your L1 Model 1S or Model II system. Packing two 10" high-excursion woofers in a compact, roadworthy enclosure, the B2 features a rear panel switch that lets you select higher or lower bass levels to suit your particular application. Proprietary technology in your L1 system automatically senses the switch position and provides correct equalization and power. If you require maximum bass impact from your L1 PA system, the Bose B2 bass module is what you need.

Bose B2 Bass Module at a Glance:
  • If powerful bass is what you need...
  • Designed expressly for Bose L1 Model 1S and Model II systems
  • Selectable bass output gives you setup flexibility
If powerful bass is what you need...

The Bose B2 bass module is ideal for L1 Model 1S or Model II applications in larger venues or anytime you really want to pack a wallop. If you're a DJ or in a band, the B2's solid extension down to 40Hz is just what you need to get your audiences on their feet - and keep them there!

Designed expressly for Bose L1 Model 1S and Model II systems

The Bose B2 bass module is designed specifically for the company's L1 Model 1S and Model II PA systems. The B2 even has interlocking endcaps that allow up to two B2 modules to be stacked together (requires optional A1 PackLite amplifier). The B2 bass module ships with a protective slip cover and the NL4 connecting cable

Selectable bass output gives you setup flexibility

You'll enjoy the flexibility afforded by the B2's three-position sensing switch. For less-demanding applications in smaller venues, keep the switch in the normal or "-" position. When you need maximum low end, simply switch to the "+" position, and you're gold. If you've got a band, you'll definitely appreciate the B2's heftier output, which provides additional bottom end for kick drums and bass guitars.

Bose B2 Bass Module Features:
  • Engineered specifically to work with the L1 Model II and Model 1S systems
  • More powerful bass output than B1 bass module
  • Proprietary Bose technology automatically adjusts and optimizes for your specific L1 model
  • Features two 10" high-excursion woofers mounted in a rugged enclosure
  • 3-position sensing switch allows bass output to be adjusted for different applications
  • Interlocking end caps allow up to two B2 bass modules to be stacked together
  • NL4 cable and protective slip cover included
Go for the low end gusto with the Bose B2 Bass Module!

A lot of bang

Wow this thing can really shake up the crowd. I haven't even used the max setting yet.

A world of difference

I've been using the Bose L1 model 2 system for nearly a decade and always liked it a great deal. One thing I didn't love was the fact that you don't get a big bottom and kicked in the chest like with box and speaker systems. I replaced my pair of B1 units with one B2 unit and the difference was absolutely amazing. Worth every penny. WSS

Bose B2 Bass Module

Super piece of equipment. A great enhancement for a midi accordion using a KetronX4 module and the Bose L1 model 1S. This gives the full complete round sound of a trio, quad or big band. You don't have to play loud with an ear splitting sound. This is a complete round sound that fills a four or five hundred room capacity with a full and complete sound that doesn't hurt your ears and annoy your senses. The round sound put out makes you feel that your part of the group. I have been accused of being a jazz box man but really I play swing blues and boogie woogie. This Bose equipment really does the job. Easy to set up and easy to take down and haul. Really great "Try it You'll Like it".

Bose B-2 Sub

Excellent, lots of bass well worth it!!

Great Sub!

I use the B2 with the L1S system and I think they're a great combination. My rock trio uses two L1S systems with 2 B2 subs and a Mackie ProFX mixer. We run the bass guitar directly into the board (with help from a SansAmp) and the kick drum as well. The B2 packs plenty of low-end punch to carry everything. So far we've left on the normal bass setting, no enhancement needed.
