The loudspeaker shall be of weatherproof, all-metal
construction, with driver enclosed within a weather-
proof housing. The loudspeaker shall include a self-
aligning, field-replaceable diaphragm.
Screw terminals shall be provided for connection to
the audio line. A plastic cover shall be provided to
protect the connectors and impedance selector
switch, and provide strain relief for the audio line.
An all-purpose mounting bracket shall provide pre-
cise positioning in the vertical and horizontal planes
with a single adjustment. The bracket shall include
banding slots to permit mounting the loudspeaker on
beams or pillars. Bracket and loudspeaker shall be fin-
ished in textured mocha enamel. The unit shall mea-
sure 9" diameter by 9-1/4" D. Product weight shall be
