Bose Professional ShowMatch SM20 DeltaQ Array Loudspeaker

The Bose ShowMatch SM20 is a full-range array module designed for long-throw applications in touring and installed sound. Featuring 20° vertical coverage, it allows fewer modules to cover the same area compared to smaller-angle models. Built with DeltaQ technology, the SM20 provides precise control of horizontal coverage and improved consistency throughout the listening area.
