The loudspeaker shall be a Bogen Model ____
(specify SPT30A or SP308A), or approved equiva-
lent, reentrant type horn loudspeaker. The fre-
quency response shall be 225Hz to 14kHz. Rated
power output shall be 30 watts, RMS continuous.
Dispersion shall be 100º. Sound pressure level,
measured four feet on axis with 30 watt input @
1000Hz, shall be at least 125dB.
Use for SPT30A. The unit shall incorporate a
seven-position weather-sealed switch, to allow
matching the loudspeaker to a 25V or 70V con-
stant-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. Impedance
shall be adjustable to 2500, 1300, 666, 333, 167, 89,
or 45 ohms.
Use for SP308A. The unit shall have an imped-
ance of 8 ohms.
