The Bose L1 Pro32 portable PA system with Sub2 powered bass module packs a serious punch that belies its small footprint design. With 32 articulated 2" neodynuym drivers, the Bose L1 Pro32 provides an amazingly high output with an extended low frequency down to 42Hz. This makes it an excellent choice for medium-to-large-sized clubs, bars and venues, as well as for mobile DJ and karaoke setups. No matter how your audience is setup, the L1 Pro32 offers a wide 180-degree range, so everyone present will enjoy the same experience. The included Bose Sub2 bass module offers up unsurpassed low-end clarity down to 35Hz. Bose built the Sub2 with a 10"x18" high-excursion neodymium RaceTrack driver to give you the same kind of performance as a 15" woofer but in a much more compact design.
