Unique, all-in-one system delivers clear, powerful sound across the stage and throughout small to medium-sized venues. Hear what your audience hears, and eliminate conventional monitors, mixers and PA systems. Includes one B1 bass module for enhanced low-end performance.

Based on over 10 years of groundbreaking research, the L1 Model I concert sound system features Spatial Dispersion loudspeaker technology, available only from Bose. The loudspeaker's proprietary, vertical design helps fill the room with clear sound like no ordinary concert speaker can.

As Guitar World describes it, the "… sound radiates and fills the room in a way far more natural than a typical loudspeaker … it's a real breakthrough in amplified sound." Key benefits of this L1 system:

• Projects clean, detailed sound evenly across the stage and throughout an audience of up to several hundred, with little change in tone or volume
• Produces smooth, consistent tone, whether you're in front of the loudspeaker or off to the side
• Reduces much unwanted room reverberation
• Eliminates conventional monitors, mixers and PA
• Sets up and breaks down quickly; fits easily into a car trunk

Wide, uniform coverage—throughout the room

The innovative L1 Model I Cylindrical Radiator® loudspeaker has a line array of 24 small drivers mounted into a vertical enclosure for wide, horizontal sound coverage of nearly 180 degrees. In comparison to conventional stage speakers, volume and tone diminish very slowly over distance.

The loudspeaker's wedge-shaped dispersion pattern sends very little audio up or down, preventing much of the room reverberation that can muddy your sound.

Unlike traditional amplification setups, a Bose® L1 system lets you, your fellow musicians and the audience hear the same sound. You don't need any other stage monitors, mixers or PA speakers. Your L1 system replaces them all with one sleek, powerful setup.
