General Product Description

The Electro-Voice

®

 EP925 series Duplex

®

 loudspeaker systems

are complete two-way ceiling loudspeaker packages. The package
consists of a rear enclosure, grille, and a two-way 12-in. Duplex®
loudspeaker which features a rectangular-coverage 90° x 90° horn
driven by a 1-in. compression driver coaxially mounted to a 12-in.
low-frequency cone driver with a high-temperature voice coil
assembly. The system is offered in either a 60-watt or 100-watt
line-matching transformer package. Each system utilizes a
dual-section crossover network with a self-resetting protection
circuit for the compression driver.

The EP925-60T utilizes a transformer that offers a selection of 7.5.
15, 30 and 60 watts delivered to the loudspeaker system using
either 25-V, 70-V or 100-V lines.

The EP925-100T utilizes a transformer that offers a selection of
50, 70, 100, 140 and 200 watts delivered to the loudspeaker
system using either 70-V or 100-V lines.

The rear enclosure provides an optimum internal volume,
ensuring extended low-frequency performance. It is constructed
from rugged heavy-gauge, cold-rolled steel, finished with a
black-wrinkle epoxy powder coat. In addition, the interior is lined
with a polyester batting blanket to ensure optimum acoustic
performance. Three hanging points are provided through the
rear cover each consisting of a 3/4-in. length of 3/8-16 threaded
rod or “all-thread” (see Mounting the System in a Ceiling). For the
EP925-60T and EP925-100T transformer models, the rear cover
provides access to both a dual terminal block for direct connection
to the speaker and an 8-pin terminal block that allows direct
connection to each of the transformer taps.
