General Product Description
Model 850T is a wide-range, integrated horn and driver system
with a single driver unit having two coaxial horns coupled to opposite
sides of the driver diaphragm.
The folded construction of the rear horn coupled with the smaller
dimensions of the front horn, present a 1,000 Hz acoustic crossover.
This separation of frequencies provides a more extended
high-frequency response and cleaner sound.
The 150° horizontal by 110° vertical dispersion pattern is beneficial
in many applications requiring a wide coverage pattern. Furthermore,
excellent loading is maintained to a low-frequency cutoff of 180 Hz.
Architects’ and Engineers’ Specifications
The loudspeaker shall be of the integrated driver and horn style,
utilizing two coaxial horns coupled to opposite sides of the driver
diaphragm and a larger horn compression molded from fiberglass,
a zinc die-cast front horn and phenolic-constructed inner horns.
The driver uses a high-temperature rated 5.2 cm (2.0-inch) diameter
voice coil.
The axial frequency response will extend from 280 to 8,000 Hz and
the horn shall exhibit a low frequency cutoff of 180 Hz. Sound
pressure level will be 105 dB (1 W/1 M) with a 500 to 5,000 Hz pink
noise signal applied, and the horn will produce a horizontal
beamwidth of 150° and a vertical beamwidth of 110° at 2 kHz. The
horizontal coverage shall be constant over the frequency range of
3 kHz to 10 kHz.
The loudspeaker shall be compression molded fiberglass capable
of satisfactory mechanical performance in the temperature range
from - 40°C to +40°C and not subject to sunlight embrittlement.

installation and a variety of adjustments, is provided.
The loudspeaker shall be 52.0 cm (20.5 in.) high, 26.5 cm (10.5 in.)
wide and 51.0 cm (20.0 in.) long. The loudspeaker shall be the
850T, which includes a 70-V transformer and weighs no more than
