ShowMatch SM20 DeltaQ Array loudspeaker
Bose Professional ShowMatch DeltaQ SM20 full-range array modules provide 20° nominal vertical coverage with included field-changeable waveguides offering choice of 70° or 100° horizontal coverage and optional accessory 120° waveguides.
Features
Replace single waveguide panel to form horizontal asymmetrical patterns. The 2-way module requires external power amplifiers (2- channels) and DSP to provide full-range response from 59 – 18,000 Hz with peak array output of up to 145 dB.
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.
