2-WAY HORN LOADED WEATHER RESISTANT
FULL-RANGE 120W/70V/100V LOUDSPEAKER
The R.5-66T two-way, full-range loudspeaker system is
engineered to provide quality full-range sound projection in
a variety of outdoor and indoor applications. Its wide range,
smooth frequency response and high efficiency ensures both
high fidelity music reproduction and superb projection of
clear intelligible speech with very low distortion. An input
transformer with switchable taps provides impedance
matching to 70V or 100V lines. Five year limited warranty.

The loudspeaker system shall be a horn-loaded, two-way, coaxial design consisting of one 12" Ferrofluid-cooled driver and one 1" exit com-
pression driver mounted on a horn inside the cabinet. The drivers shall be connected to a passive crossover network with a crossover fre-
quency at 1.5kHz with driver protection using high positive current coefficient resistors. The cabinet shall be a roto-molded polyethylene
enclosure providing weather and UV resistance with three layer weather resistant grille. The input connection shall be one 12' (4m) SJOW
#16 gauge cable with stripped ends. The enclosure shall incorporate five 3/8-16 rigging points for multiple mounting options. In addition,
the loudspeaker will be supplied with one stainless steel yoke bracket and one multi-tap transformer for 70V and 100V inputs. The loud-
speaker system shall have an amplitude response of 90Hz-10kHz (+/- 5 dB SPL), an input capacity of 120W (70V/100V), 100 dB SPL sen-
sitivity @ 2.83V / 1 meter between 250Hz-4kHz at a nominal 8 Ohm impedance. The nominal dispersion shall be 50 x 50 over a frequen-
cy range of 1kHz to 16kHz. The dimensions of the enclosure are defined as 16" x 16" x 16" (HWD) at a weight of 37lbs.
