Bose® Corporation was founded in 1964 by Dr. Amar G. Bose. The company was founded on the principal of 'Better Sound through Research', and continues to be dedicated to breakthrough technologies and quality products that enrich people's lives. One such breakthrough is the L1® portable line array systems. L1 models are complete, portable PA systems that deliver clear, balanced sound and set up in minutes. A proprietary articulated line array delivers 180-degree coverage, consistent tonal balance and less SPL drop-off than conventional systems. Bose F1® systems are first powered portable loudspeakers that let you control vertical coverage pattern. So whether you're playing at floor level, on a stage or facing raked seats or bleachers, you can adapt your PA to the room.
