Claiming ‘significant advantages over conventional line array loudspeakers’, Bose Professional has announced the ShowMatch DeltaQ array loudspeaker with field-changeable waveguides for installation and portable applications
DeltaQ array technology provides selectable coverage patterns that direct sound energy to the audience by allowing directivity (Q) to vary with each array module. Modules are available with 5°, 10° or 20° vertical coverage that allows J-array, constant-curvature or DeltaQ array configurations.
ShowMatch DeltaQ arrays also claim the highest full-range output for their size class, with 145dB 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.
The field-changeable waveguides vary horizontal coverage for improved acoustic performance in left/right arrays. Modules ship with both 70° and 100° waveguides, with optional 55° and 120° kits available. Compact, road-ready enclosures with removable side caps optimise 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 30Hz. Integrated rigging allows mixed arrays with full-range modules, or subwoofer arrays including cardioid and groundstack configurations. The subwoofer measures 21.2-inch x 30.1-inch x 30.5-inch (540 x 765 x 775mm) and weighs 136.5lbs. (61.9kg). Frequency response of the full range models is 59Hz-18kHz (-10dB).
Also offered is a 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 v6.9 Modeler software with a toolset for ShowMatch loudspeakers. Additionally, Bose will release an interactive design aid called Bose Array Tool, allowing quick configuration of its array loudspeakers via direct-field coverage mapping.
