The new L1 Model 1S portable line array system delivers a potent combination of portability and performance. It's compact and light enough to make setup quick and easy, yet powerful enough to fill a mid-sized venue. This system works well for solo musicians, bands and public speakers. Includes one B1 bass module for enhanced low-end performance. Put your PA behind you The vertical configuration of the system's small, closely spaced drivers allows the L1 Model 1S system to project sound forward and to the sides delivering 180-degree coverage but very little up and down, reducing unwanted reverberation. This produces consistent tonal balance as sound spreads more evenly across the stage and into the audience, and the volume level drops off much more slowly than with a conventional speaker. Unique Bose® technologies enable the system to serve as both PA and monitor. It can be positioned behind or to the side of the performer and you hear just what the audience hears. You're in control, and there's no need for conventional monitors, mixers and PA systems. Convenience to go he three components of the L1 Model 1S system upper array, lower extension and power stand connect quickly and easily without the need for separate speaker stands.
