Description
Bose RoomMatch Utility RMU 105 2 Way Compact Foreground Fill Loudspeaker White Single
The RoomMatch Utility RMU105 ultra-compact foreground/fill loudspeaker is intended for use in high-quality background/ foreground music and zone-fill applications that require excellent audio, minimal physical size and high design aesthetics. 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 5.25-inch woofer provides vocal-range output, and a 100 deg x 100 deg high-frequency horn provides consistent coverage with either vertical or horizontal mounting.
