The L1 Model 1s portable line array system delivers a potent combination of portablility and performance.

The Bose L1® Model 1S with Dual B1 Bass Modules is a fully portable line array modular PA system with interlocking components that set up and tear down in minutes. Designed to reach crowds of up to 300 people, system has a total power rating of 375 Watts and a maximum 112 dB SPL output for ample volume. Vertical configuration of system's small, closely spaced drivers allow forward sound projection, and to the sides, delivering 180-degree coverage with little up and down, reducing unwanted reverberation. Produces consistent tonal balance as sound spreads more evenly across the stage and into the audience, with slower volume level drops offs than with conventional speakers. Unique Bose® technologies enable system to serve as both PA and monitor. Can be positioned behind or to the side of the performer wth no need for conventional monitors, mixers and PA systems. Components include upper array, lower extension and power stand that connect quickly with no need for separate speaker stands. Includes carry bags for easy transport.
