Framingham, MA – 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. ShowMatch DeltaQ arrays provide significant advantages over conventional line array loudspeakers.
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-degree, 10-degree or 20-degree 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-inch 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. Modules ship with both 70-degree and 100-degree waveguides, with optional 55-degree and 120-degree kits available. Compact, road-ready enclosures with removable side caps optimize design for both installed and portable applications – from small clubs and houses of worship, to the largest performing arts centers and concert-sound amphitheaters. Integrated rigging allows up to 24-box arrays.
A matching-width 18-inch ShowMatch DeltaQ subwoofer provides low-frequency extension down to 30 Hz. Integrated rigging allows mixed arrays with full-range modules, or subwoofer arrays including cardioid and ground-stack configurations. The subwoofer measures 21.2″ x 30.1″ x 30.5″ (540 x 765 x 775 mm) and weighs 136.5 lbs. (61.9 kg).
Also offered is a full set of rigging accessories including array frames, pullback brackets, ground-stack brackets, pickup-point adapters, and fixed-installation quick pins.
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.
