The Bose(r) L1 Model II system with single B2 Bass Module delivers wide coverage and smooth tonal balance. And it's packed with proprietary Bose technologies designed to improve your amplified sound. 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. This package includes one B2 bass module for more flexibility and even greater power at the low end. The system's breakthrough loudspeaker produces wide, uniform sound coverage of nearly 180 degrees -- onstage and throughout an audience of up to 500 -- 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.
