The Tannoy SAT SUB is a compact, powered subwoofer specifically engineered for commercial distributed audio systems, providing extended low-frequency reinforcement in a discreet, wall-mountable package. Designed to complement Tannoy's SAT Series full-range satellite speakers, it fills out the bottom end of music and audio program material in applications such as retail stores, restaurants, hotel lounges, and corporate environments where a full, balanced sound is desired without the footprint of a floor-standing subwoofer. Its compact size and purpose-built mounting system allow it to be installed unobtrusively on walls or within custom cabinetry, making it an ideal solution for spaces where aesthetics and space utilization are as important as audio performance.

The subwoofer is self-powered, housing an efficient Class-D amplifier matched to its driver and enclosure. This integrated design simplifies installation by eliminating the need for an external amplifier and dedicated crossover, as it typically connects via a high-level input from the main system amplifier or via a low-level input from a system processor. It includes essential controls such as level adjustment, a variable low-pass filter, and a phase switch, allowing installers to fine-tune its integration with the satellite speakers for a seamless transition and smooth overall frequency response. The enclosure is constructed from durable materials with a finish that blends into commercial interiors.

As a component of a well-designed commercial audio system, the Tannoy SAT SUB adds impactful bass presence that satellite speakers alone cannot reproduce. It enhances the listening experience by providing the warmth and depth necessary for modern music and audio content, ensuring the system sounds complete and engaging. By offering extended low-frequency response in a practical, installable format, it enables system integrators to deliver high-quality, full-range audio in environments where conventional subwoofers would be impractical.
