Description

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.

Fitur

  • DeltaQ™ technology – defines the next-generation in loudspeaker array design with selectable coverage patterns that more precisely direct sound to audience areas for improved sound quality and vocal clarity with fewer boxes versus line arrays.
  • ShowMatch™ companion 1x 18” subwoofer – for low-frequency extension down to 29 Hz with mixed mid/high and subwoofer ShowMatch arrays
  • Bose LF18 neodymium 18-inch, high-excursion, 4.5-inch voice coil, transducer provides maximum performance (same transducer as in Bose RMS218)
  • Integrated 4-point “quick pin” rigging – allows arrays of up to 18 subwoofers with 10:1 design factor
  • Front-grill mounted NL4 input, plus rear NL4 inputs – allow easy setup for “reversed-box” cardioid arrays
  • Integrated pole-cup adapter – allows use with other mid/high loudspeakers and accessory mounting poles
