Bose ShowMatch SMS118 Subwoofer - Single 18 inch Sub
Vendor: Bose
Bose ShowMatch SMS118 Subwoofer - Single 18 inch Sub
Bose Professional ShowMatch SMS118 subwoofers are carefully designed especially to use alongside DeltaQ array loudspeakers and be able to extend low-frequency response all the way down to 29 Hz. By the use of accessories and optional array frames, the Bose ShowMatch SMS118 integrated rigging and enclosure width, is allowing fast integration in arrays with ShowMatch full-range modules. The Baltic birch enclosure, portable rated, can also be used for ground-stack applications and the integrated mounting-pole adapter is included for use with other mid/high loudspeakers.
FEATURES
- DeltaQ technology is the next-generation array design that allows “Q” (directivity) to vary with each module in the array for more consistent coverage over wide frequency range, reduced array weight and cost, and outstanding vocal clarity. Arrays can cover large vertical angles with fewer boxes.
- ShowMatch DeltaQ 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 safety factor
- Front-grill mounted NL4 input, plus rear NL4 inputs, allow easy setup for “reversed box” cardioid arrays
