Bose S1 Pro Plus

Take your show anywhere with an all-in-one sound system built for performers and presenters. The Bose S1 Pro+ combines a powerful full-range speaker with a 3-channel mixer and rechargeable battery, delivering clean, room-filling sound on the street, in the studio, or on stage. Set it upright on a table, tilt it back, use it as a floor monitor, or mount it on a 35 mm pole—the onboard Auto EQ adjusts to each position so your mix stays balanced.

Channels 1 and 2 use XLR-¼″ combo inputs with ToneMatch presets, 2-band EQ, and reverb to make vocals and acoustic instruments shine. Channel 3 handles Bluetooth® streaming or 3.5 mm aux so you can play tracks and break music without extra gear. Expand easily via the line output to feed another speaker or a recorder. For clean stages and fast setups, the S1 Pro+ includes built-in wireless receiver bays for optional Bose mic/line and instrument transmitters—dock to charge, pair instantly, and perform cable-free.

Dial in mixes from the speaker or from your phone with the Bose app: adjust levels and EQ, recall scenes, and keep firmware current. A rugged molded cabinet with an integrated carry handle is ready for travel, and the removable rechargeable battery lets you perform where outlets aren’t an option.
