The Electro-Voice MM2TC 25W Surface-Mount Waterproof Gray Paging Projector is a conservatively rated 25-watt "submergence-proof" speaker designed for wall, ceiling or bulkhead mounting. The driver employs a diaphragm with a phenolic impregnated linen-base and 2.0-inch voice coil with "W" shaped Alnico V magnet structure. Provisions are made in the housing for installation of a matching transformer such as the University Sound model 5030 (30 W).

The voice-coil/diaphragm assembly is protected by a special anit-fungicide treatment and is easily accessible for cleaning by removal of the die-cast reflector on the front of the speaker. The MM2TC 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.
