Bose 840917-1100 Sub 2 Powered Bass Module

The Bose Sub 2 Powered Bass Module (840917-1100) is a portable subwoofer engineered to extend the low-frequency reach of virtually any PA system. At its core is Bose's proprietary 10" × 18" high-excursion neodymium RaceTrack driver — an oval woofer that moves as much air as a traditional 15-inch cone while fitting into a more compact, tour-friendly cabinet. With a frequency response reaching down to 37 Hz, the Sub 2 delivers deep, musical bass that fills rooms and outdoor venues without the bulk and weight associated with conventional subwoofers of comparable output.

Connectivity is designed for maximum flexibility. A proprietary SubMatch connection provides plug-and-play integration with the Bose L1 Pro32 portable line array, while standard line-level inputs and outputs with selectable crossover modes allow pairing with any powered loudspeaker or mixer. An independent sub level control knob on the rear panel gives performers quick, hands-on bass adjustment during a set. For larger events, multiple Sub 2 units can be stacked to increase output, with an optional Cardioid Mode that focuses bass energy toward the audience and reduces onstage rumble — a valuable tool for managing feedback and keeping performers comfortable on stage.
