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 B2 bass module for more flexibility and even greater power at the low end.
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.
Sound advantages—only from Bose
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.
Full, flexible bass
The high-performance B2 bass module delivers greater low-frequency output when you need more powerful bass for larger audiences. The module includes three settings for increased flexibility. The normal setting is ideal for bass guitar or when miking a kick drum. A higher setting is designed for DJ/music playback applications. And the lower setting works well for acoustic guitar and vocals.
You can power one B2 bass module on a single L1 power stand. And the optional PackLite® power amplifier lets you add a second B2 bass module for maximum low-end power.
Easy and efficient
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.
Multichannel flexibility
The optional 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.
