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

(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.
