RoomMatch Asymmetrical 10° vertical modules


Bose RoomMatch DeltaQ array loudspeakers are designed for permanent installation in the finest performing arts centers, auditoriums, sports arenas, dance clubs and houses of worship, in which the large-format waveguides with choice of 42 coverage patterns can provide best-in-class coverage control, sound quality and vocal clarity even in venues with difficult acoustics.


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
