L1®
L1 is often used to refer to one system including the L1 Cylindrical Radiator® loudspeaker, Power Stand, and one or more B1 Bass Modules. We don't use PAS (and never officially did) out of respect for someone else's trademark. MikeZ-at-Bose tells us "L1 is simply 'Line Array 1'." Message Board discussion
