TECHNICAL DATA ShowMatch™ SM20 DeltaQ™ array loudspeaker Product Overview 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 up to 145 dB. Key Features • eltaQ™ technology – defines the next-generation in loudspeaker array design with selectable coverage patterns that more D precisely direct sound to audience areas for improved sound quality and vocal clarity with fewer boxes versus line arrays. • eplaceable waveguides – ships with 100° waveguides installed with 70° panels included to allow coverage change. R Largest-in-class size provides better coverage and vocal clarity. Change single panel for asymmetrical patterns. Optional 120° waveguides for SM20. • ompact, portable enclosure – Versatile design allows both fixed install and portable applications, from small clubs and C houses of worship to the largest performing arts centers and AV productions. • our-sound output level – 4x Bose EMB2S compression drivers, improved with more HF output, and 2x 8-inch neodymium T high-power woofers allow peak array output up to 145 dB SPL. • -point “quick pin” rigging – Fast, easy setup with up to 24 full-range modules and 10:1 design factor. 3 • emovable side guards – provide rigging guard and hand holds for portable applications. Easily removed for permanent R installs to reduce width and improve sight lines .
