Description
The Bose FreeSpace Acoustimass Subwoofer is designed to provide flush-mount bass augmentation for new and existing background music systems. It features one 5.25 (133 mm) woofer that delivers deep bass down to 40 Hz without audible distortion.
Features:- Low-frequency loudspeaker featuring one 5.25 (133 mm) woofer that delivers deep, non-localized bass support down to 40 Hz without audible distortion. For flush, ceiling, pendant and wall-mount applications
- Acoustimass speaker technology filters out audible distortion to deliver non-localized bass
- Designed to work with the FreeSpace 3 flush and surface satellite speakers, or existing systems where additional bass reinforcement is desired
- Module design allows parallel connection of multiple bass modules and can accommodate two or four FreeSpace 3 satellites per bass module
- Plenum rated for use in air handling spaces (with optional plenum cover)
- Selectable 70/100V or low impedance with transformer tap adjustment under speaker grille
