Bose Sub2 Portable Powered Bass Module

The Bose 840917-1100 is a Sub2 portable powered bass module that adds deep, confident low-end energy to any small or medium portable PA system. It uses a 10 × 18-inch high-excursion neodymium RaceTrack driver that reaches down to 37 Hz, so kick drums, synths, and bass guitars come through with weight while the enclosure stays slim enough to move easily between gigs.

For performers who travel with the Bose L1 Pro32 array, connection is as simple as running a single SubMatch cable that carries both power and audio. That same cable lets you control levels from the L1 Pro32 mixer, cutting setup time when you have only a few minutes before the doors open.

If you stack two Sub2 modules, Cardioid Mode lets you aim the bass toward the audience while reducing energy on stage. The result is tighter monitoring for singers and instrumentalists and less feedback in reverberant rooms. When the event calls for a different loudspeaker brand, the Sub2 can still join the rig through its line input and output, with switchable crossover settings that blend smoothly with tops from other manufacturers.

A built-in 1000-watt Class-D amplifier delivers punch without the need for an external power source. The enclosure, made for life on the road, resists scuffs yet remains light enough for one person to carry. An integrated pole mount on top of the cabinet lets you raise a mid-high speaker to the right height without extra hardware, ideal for DJs, corporate presenters, and worship teams who set up in diverse venues.
