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

Bose L1® Model 1S with B1 Bass ModuleThe L1 Model 1S portable line array system delivers a potent combination of portability and performance. It's compact and light enough to make setup easy, yet powerful enough to fill mid-sized venues. Includes one B1 bass module for enhanced low-end performance. 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 to produce consistent tonal balance as sound spreads more evenly across the stage and into the audience, while volume level drops off more slowly than with conventional speakers. Unique Bose® technologies enable system to serve as both PA and monitor and can be positioned behind or to the side of performer, eliminating the need for conventional monitors, mixers and PA systems.


  • Spatial Dispersion™and Articulated Array® speaker technologies in the loudspeaker produce wide, uniform sound coverage.
  • 12 small drivers are arranged using Articulated Array speaker technology in a slim, vertical enclosure-creating nearly 180 degrees of horizontal coverage and consistent tonal balance.
  • Integrated power amplifiers in the power stand provide clean, precise amplification for L1 Model 1S system with up to two B1 bass modules or one B2 bass module.
  • ToneMatch® port is built into power stand for digital audio and power connection to ToneMatch audio engine.
  • Analog input, trim control and signal/clip LED for line-level analog input via ¼" TRS phone cable. Can be used for instruments or other audio sources like DJ mixers, MP3 players, computers or DVD systems.
  • Bass module out for amplified bass output signal to the bass module. L1 system automatically adjusts equalization appropriately when bass modules are connected.
  • Interlocking design of lightweight components eliminates need for speaker stands and speaker wires. Setup takes only minutes.
  • Retractable legs provide stability for streamlined power stands and loudspeakers. Four retractable legs fold out of power stand simultaneously for quick setup and compact transport.
  • Convenient carry bags-one each for the loudspeaker, power stand and bass module.
