Bose RoomMatch Utility RMU 108 2 Way Small Format Under Balcony Fill Loudspeaker White Single

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.

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 deg x 60 deg 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
• Flexible mounting with included U-bracket rear enclosure panel also includes 4 x M8 threaded inserts in 5.0 x 2.75 inches (127mm x 70mm) pattern to accept third-party accessory mounting brackets
