Bose Professional Sub1 Powered Bass Module

Bose Professional Sub1 is a powered bass module designed for portable sound reinforcement applications. It enables low-frequency reinforcement for performers, presenters, and audio operators, supporting mobile PA and live sound workflows. This makes it ideal for situations where compact size and extended bass response are critical.

The bass module operates using an integrated Class D amplifier and a high-excursion RaceTrack low-frequency driver. It supports connection to compatible systems through analog inputs and proprietary SubMatch connectivity for combined power and audio delivery. Integrated DSP manages signal processing and system behavior.

The system supports portable applications that require flexible deployment and scalable low-frequency output. It is suited for live performances, presentations, and mobile DJ setups. The design allows integration with compatible Bose portable loudspeakers and PA systems.
