The Bose L1 Model II system's breakthrough Spatial Dispersion loudspeaker system produces wide, uniform sound coverage of nearly 180 degrees. It projects that sound onstage and throughout an audience of up to several hundred — with little drop off in volume and tone. The Bose L1 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 — all courtesy of the Bose L1 Model I
