Product Description
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. 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.
