  • The RoomMatch Utility RMU108 small-format sound reinforcement loudspeaker is intended for use in high-quality foreground music, under-balcony, zone fill and vocal-range floor monitor applications.
  • The design features a single Bose® EMB2 compression driver to provide mid/high frequency voicing similar to that of RoomMatch full-range array modules and all RoomMatch Utility models. 
  • A single 8-inch woofer provides full-range output and a multi-angle enclosure with rotatable high-frequency waveguide increases mounting flexibility.

Applications

  • Under-balcony and zone fill
  • High-quality foreground music
  • Stage-front fill
  • Vocal-range floor monitor

 
Key Features

  • Award-winning RoomMatch sound – now in smaller, 2-way, point-source designs for high-level foreground music, under-balcony, zone-fill and vocal-range floor monitor applications
  • Bose EMB2 compression driver – for lower distortion and improved vocal clarity compared to conventional foreground/fill models; also provides consistent mid/high sonic character compared to that of RoomMatch full-range and other RoomMatch Utility models
  • 90° x 60° constant-directivity high-frequency horn – gives wide, even coverage and may be rotated in enclosure
  • 1 x Bose LF8 8-inch woofers – with 2.0-inch long-excursion voice coil extends response to 80 Hz for lowest vocal range
  • 80 Hz – 16 kHz frequency response and 121 dB maximum peak SPL – deliver the performance required for most demanding applications
