Bose L1 Model II System With B2 Bass Module

Our most advanced L1 system for an audience of up to 500. With a 24-speaker articulated line array providing 180 degrees clear, even coverage, it combines our best sound reproduction with easy transport and setup. Designed to work with the T1 ToneMatch® audio engine, which provides four additional inputs, our largest library of ToneMatch presets and a complete suite of studio-class effects and processing.


High-performing, powered, portable two-way loudspeaker system with a 195° H x 0° V nominal dispersion designed for the production and reproduction of live music, music playback, speeches and A/V sound reproduction

24-driver articulated line array loudspeaker technology produces wide, uniform sound coverage throughout the entire listening area—even off to the extreme sides

Consistent front-to-back coverage, 24 drivers mounted in a vertical line array produce little drop in sound pressure level per doubling in distance than a conventional point source

Retractable folding leg mechanism for easy transport

Lightweight, interlocking components

Expandable bass design supports the use of multiple B1 bass modules or a single B2 bass module

Digital Ethercon port provides single-wire connectivity for the T1 ToneMatch audio engine
