Boost your performance with the L1 Model II system, our most advanced portable amplification system for musicians, DJs and public speakers. The loudspeaker delivers 180 degrees of horizontal sound coverage and our smoothest tonal balance—across the stage and throughout the room. Includes one B1 bass module for enhanced low-end performance.
Like the original, award-winning Bose L1 system, the Model II sound system is an all-in-one innovation that replaces conventional monitors, mixers and PA speakers. And this professional sound system is packed with proprietary Bose technologies designed to improve your amplified sound.
The system's breakthrough loudspeaker produces wide, uniform sound coverage of nearly 180 degrees—onstage and throughout an audience of up to several hundred—with little dropoff in volume and tone.
The Model II system also features Articulated Array speaker technology for better tonal balance. The loudspeaker's 24 vertically mounted drivers are precisely angled to create clearer highs and more consistent tone in the room. Even people off to the sides of these stage speakers enjoy well-balanced, detailed sound.
The B1 bass module is our more portable bass option. It is considerably lighter and smaller than conventional bass bins required for the same performance. And it ensures more accurate amplification of lower notes for most voices and instruments.
With the L1 Model II system, you can power up to two B1 bass modules or one B2 module on a single power stand. And the optional PackLite® power amplifier lets you add a second B2 bass module for maximum low-end power.
The L1 Model II power stand weighs only 24 pounds, and its four retractable legs make it easy to transport and set up. The power stand also has a simplified control section; the single line-level input can be used with instruments, mics, mixers, laptops, MP3 players or DVD systems.
All of the system's components are also built to handle the road. The loudspeaker has a rugged, reinforced grille, and each package includes padded carrying bags for major components.
Multi-Channel Flexibility
The optional (not included) T1 ToneMatch audio engine adds four more channels, so you can expand the system and connect additional instruments and microphones. You can also use the ToneMatch engine to fine-tune your sound with powerful, proprietary tone-shaping tools.
