If you're in a band that preforms live, surely you know what a pain it is to lug around all of your heavy equipment. The engineers at Bose have come up with a solution to your misery; the L1 Compact system. Using their patented "Spacial Dispersion" technology, just one L1 unit can deliver sound across the entire stage to the audience. Bose has included two ToneMatch channels for a microphone and guitar. These inputs come with fixed presets as well. In the power stand (the bottom of the unit), there is a speaker specifically for bass. Bose products are known for their versatility, and this product is no different. There speaker collapses to fit into smaller spaces or storage, and when you have a lot of space, you can extend it. This feature makes the speaker ideal for applications as small as classrooms, and as big as musical performances.
