Sound Pressure Level in dB @ 1000Hz:
The loudspeaker shall be a Bogen Model ____ (spec-
ify SPT30A or SP308A), or approved equivalent,
reentrant type horn loudspeaker. The frequency
response shall be 225 Hz to 14 kHz. Rated power
output shall be 30 watts, RMS continuous.
Dispersion shall be 100º. Sound pressure level, mea-
sured four feet on axis with 30 watt input @
1000 Hz, shall be at least 125 dB.
Use for SPT30A. The unit shall incorporate a
seven-position weather-sealed switch, to allow
matching the loudspeaker to a 25V or 70V constant-
voltage line. Power handling capacity shall be
adjustable at 70V to 1.8, 3.7, 7.5, 15, or 30 watts, and
at 25V to 1.8, 3.7, 7.5, or 15 watts.
Use for SP308A. The unit shall have an impedance
of 8 ohms.

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 11" in diameter by 10-1/2" D. Product weight
shall be ________ (insert 6 lb. for the SPT30A, 5 lb.
