The MM2F is a submergence-proof speaker rated at 25 watts, for use in public address or paging applications.
The drivers employ a diaphragm with a phenolic impregnated linen-base and 2.0-inch voice coil, with a “W” shaped Alnico V magnet structure. The MM2F is made with six holes in its outer flange for flush mounting.
The voice-coil/diaphragm assembly is protected by a special anti-fungicide treatment and is easily accessible for cleaning by removal of the die cast reflector on the front of the speaker. The MM2F is self-draining and designed to withstand fungus, dust, salt spray, live steam, and gases. It is built to penetrate high noise levels in boiler rooms, mines, railroads, etc.
