The L1 Compact portable line array system: Carry it in one trip. Set it up in one minute. Fill the room with Bose sound. The L1 Compact system combines conventional PA and monitors into one sleek unit. Positioned behind or to the side of a performer, DJ or presenter, it delivers wide, even sound coverage throughout the stage area and audience—even off to the extreme sides. It's our smallest, lightest, easiest-to-set-up L1 system, weighing just 29 pounds.
