Bose ShowMatch™ SMS118 subwoofer is designed primarily to integrate with DeltaQ™ array loudspeakers and extend lowfrequency 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.
