Bose Professional is now shipping new ShowMatch DeltaQ array loudspeakers for both installation and portable applications, with field-changeable waveguides that help provide the best possible sound quality throughout the audience area.
DeltaQ array technology improves sound quality and vocal clarity by providing selectable coverage patterns that direct more sound energy to the audience by allowing directivity, or ‘Q’ to vary with each array module. Traditional line arrays typically have significantly less pattern control.
ShowMatch full-range array loudspeakers are available with 5°, 10° or 20° vertical coverage with class-leading versatility that allows J-array, constant-curvature, or DeltaQ array configurations. Conventional line arrays can require up to twice the box count compared to DeltaQ arrays to achieve comparable vertical coverage. DeltaQ arrays can improve sight lines, reduce rigging weight and lower system costs.
New ShowMatch DeltaQ array loudspeakers provide the highest full-range output for their size class, with 145 dB peak array output levels generated from four Bose EMB2S neodymium compression drivers and two 8″ neodymium woofers with more usable low-frequency output in smaller arrays.
ShowMatch loudspeakers feature field-changeable waveguides that vary horizontal coverage to better match audience coverage needs and can form asymmetrical patterns for improved acoustic performance in left/right arrays. A matching-width 18″ ShowMatch DeltaQ subwoofer provides low-frequency extension down to 30Hz. Integrated rigging allows mixed arrays with full-range modules, or subwoofer arrays including cardioid and ground-stack configurations.
To support ShowMatch DeltaQ array designs, Bose Professional will soon release updated version 6.9 of Modeler software with a specific toolset optimized for ShowMatch loudspeakers. Additionally, Bose will release a new interactive design aid called Bose Array Tool, allowing quick configuration of Bose array loudspeakers via direct-field coverage mapping.
