Bose Professional ShowMatch SMS118 DeltaQ Subwoofer

Utilizing DeltaQ™ technology to vary with each module in the array for more consistent coverage and better vocal clarity, the Bose Professional ShowMatch SMS118 subwoofer is the next-generation in sound delivery. Bose Professional ShowMatch SMS118 subwoofers are designed primarily to integrate with DeltaQ array loudspeakers and extend low-frequency response down to 29 Hz.

The SMS118 enclosure width and integrated rigging allows fast integration in arrays with ShowMatch full-range modules using optional array frames and accessories. The portable-rated Baltic birch enclosure may also be used for ground-stack applications and includes an integrated mounting-pole adapter for use with other mid/high loudspeakers.
