Vendor: Bose
Bose RoomMatch 70x20 Line Array Passive Loudspeaker for Churches, Arenas, Schools
Bose RoomMatch DeltaQ 70x20 array loudspeakers are designed for permanent installation in the finest auditoriums, performing arts centers, houses of worship, dance clubs and sports arenas, in which the large-format waveguides with choice of 42 coverage patterns can provide vocal clarity, sound quality and best-in-class coverage control even in venues with difficult acoustics.
FEATURES
DeltaQ technology advances line-array loudspeaker design by allowing different “Q” (directivity) for each module in the array to improve sound quality by better matching array coverage to audience areas and distance, with improved phase coherency.
42 large-format waveguide patterns – allows designers to customize array coverage to exact venue dimensions to minimize wall reflections and deliver best-in-class sound quality even in venues with difficult acoustics
Continuous-Arc Diffraction-Slot (CADS) Manifold – provides smooth high-frequency array summation and allows choice of 5 vertical-coverage patterns. Select number of array modules based on sound level, low-frequency pattern control and budget requirements, independent of total array vertical coverage
Bose EMB2 compression drivers – deliver the vocal power normally associated with 3-way systems with frequencies from 500 Hz to 16 kHz projected from the large-format waveguides for remarkably consistent coverage and vocal clarity
Integrated Rigging – allows fast installation of arrays with up to 8 full-range modules at 10:1 safety factor
Available RMS215 or RMS218 subwoofers – extend full-range performance to 40 Hz or 25 Hz, in flown or ground stack arrays
Available Bose PowerMatch amplifiers – configurable to provide optimal power for all RoomMatch modules and subwoofers; includes integrated loudspeaker DSP functions with optional Dante® digital audio network interface
