Bose RoomMatch RM9040 40 Degree Vertical Array Loudspeaker 

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™ 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
