DESCRIPTION
The University Sound MM2TC is aconservatively 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.
