Vendor: Bose
Bose RoomMatch 90x40 Line Array Passive Loudspeaker for Churches, Arenas, schools
Bose RoomMatch DeltaQ 90x40 array loudspeakers are designed to be installed permanently in the finest places for occasions like the sport arenas, houses of worship, dance clubs, performing arts centers and auditoriums, in which the large format waveguide with choice of 42 coverage patterns can provide best-in-class sound quality, vocal clarity and coverage control even in venues with difficult acoustics.
FEATURES
DeltaQ array technology improves sound quality compared to conventional line-array loudspeakers by providing better horizontal coverage control to reduce wall reflections, more vertical patterns for smaller arrays without coverage compromise, and selectable directivity or “Q” per box for consistent front-to-back coverage
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
