Bose L1 Model 1S with B1 Bass Module

Bose L1 Model 1S

Our L1 system offering a unique combination of performance and portability for an audience of up to 300. With a 12-speaker articulated line array providing 180 degrees of clear, even, sound, the system is also designed to work with the T1 ToneMatch® audio engine as well as a choice in bass modules. Easy to transport, and set up in minutes.


High-performing, powered, portable two-way loudspeaker system with a 195° H x 10° V nominal dispersion designed for the production and reproduction of live music, music playback, speeches and A/V sound reproduction

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

Consistent front-to-back coverage, 12 drivers mounted in a vertical line array produce less drop off 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 module

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