8" Moisture Resistant Loudspeaker with Dual Voltage Transformer

OUR PART #  8C10MRB-T72


The Lowell 8C10MRB-T72 is designed for utility paging and low level background music systems that may be subject to high humidity, including indoor areas and outdoor areas that are protected from direct exposure to rain, snow, sun and similar environmental elements. It’s ideal for use in greenhouses, locker rooms, hot tub areas, outdoor restaurants and cafes, and similar venues. The speaker features a wired transformer with taps for .25, .5, 1, 2 and 5 Watts at 25/70V and mounts to a standard 8-inch (203mm) grille and backbox. It can be teamed with Lowell's tamper-resistant grille model SG-8VP and surface-mount backbox model CB84-SGVP or a recessed backbox from the P68X Series.
