The BOSE B2 bass module is a high performance flexible bass solution designed for L1 Model 1S and Model II systems. It features two 10" high-excursion woofers mounted into a rugged enclosure.

For additional flexibility, the B2 includes a rear panel switch that allows for higher or lower bass levels to be selected based on application or personal preference. Proprietary BOSE technology in the L1 systems automatically senses the switch position of the B2 and provides the proper equalization and power. Interlocking end caps allow up to two B2 modules to be stacked together. Includes protective slip cover and NL4 cable.

Applications include educational and business uses, such as announcements, presentations and training demonstrations for up to 300 people. It is also useful in portable applications within houses of worship, sporting events and many other instances where a PA and bass are required.

The B2 bass module is also ideal for musicians and DJs that require higher bass output and impact. Both will benefit from the flexibility of the three-position sensing switch. Simply switch to "+" for the maximum bass output. Full bands will appreciate the B2 module's higher output, which provides additional bass for kick drums and bass guitars.

Comments about Bose B2 Bass Module:

I have three bands and have been using the Bose L1 Model 1 with the B1 bass modules for many years. We recently upgraded to the Bose L1 Model IIs with two of the B2 bass modules and Tone Match. One of these B2 modules easily replaces four of the B1 modules! Less gear, better sound, and smaller footprint are all positives with a band. I know you can buy other subwoofers for less, but the ability to dial these in with the 3-position switch on the back of each B2 module makes them very versatile!

Well Done Bose....Well done

Comments about Bose B2 Bass Module:

I have been through 4 JBL518s. I was Sick of them Cutting out and breaking so i went to the Bose B1's for the reliability they sounded fine and were consistent, but they were missing the kick in the chest that Mobile DJ's like to have. I've used the Bose B2 at 2 gigs now and i can just say WOW! no A1 packlite? No problem. I use it with my L1 classic and it works like a dream. I'll be purchasing a second B2, not out of necessity but for those gigs where I want to show off. Normally I wouldn't be so loose with my wallet but for the $$ how can you go wrong? If you have bose L-anything sell your sub and get the B2. I Promise you won't be disappointed.

Comments about Bose B2 Bass Module:

Bose has finally come out with a sub that is decent. This sub produces bass frequencies that you can not only hear, but also feel. I am using the B2's with the L1, M2's and the sound is fantastic.
