This surface-mount bass module adds low-frequency reinforcement to commercial sound systems where additional bass is needed. It uses a 5.25-inch low-frequency driver and is designed to deliver non-localized bass response down to 40 Hz.

The configuration supports selectable 70/100V or low impedance operation and allows parallel connection of multiple modules. Each bass module can accommodate two or four FreeSpace 3 satellites, making it suitable for flexible system layouts in retail stores, restaurants, bars, lobbies, and conference rooms.
