The Electro-Voice EVID C8.2 loudspeaker system is a complete
two-way ceiling loudspeaker package. The package consists of a bezel assembly,
grille, rear enclosure, 8-inch coax two-way loudspeaker and internal line-matching
transformer. The loudspeaker features a waveguide coupled titanium coated
dome tweeter. The EVID C8.2 loudspeaker utilizes a 2nd order crossover
network at 2.5 kHz, with a comprehensive protection circuit to protect
the network, woofer, and tweeter drivers from excessive power levels.
The EVID C8.2 utilizes a transformer that offers a selection of 1.88 (70-V
only), 3.75, 7.5, 15 or 30 watts delivered to the loudspeaker system using
either 70-V or 100-V lines, or 8 ohm bypass. Selection is via a convenient
switch on the front baffle. The perforated grille is finished in semi-gloss
white powder-coated enamel. The baffle and bezel are constructed from
UL 94V-0 rated ABS. The rear enclosure is constructed from zinc-plated,
heavy gauge steel. The rear enclosure, with fiberglass damping material,
provides an optimum internal volume for extended low-frequency performance.
A rear cover, with provisions for a junction box fitting, provides access
to a 4-pin terminal block that allows direct connection to the speaker
with 12 gauge wire and provides pass through to additional speakers.
A tile bridge is included for safe suspension of the Electro-Voice C8.2
ceiling systems in a drop ceiling that uses mineral wool, or other fiber-based
ceiling tiles. The Electro-Voice EVID line of ceiling speakers has been
designed to work together as a complete system in a wide range of different
ceiling constructions. They provide wide dispersion, high-efficiency,
high-maximum output, ease of installation, and wide-range reproduction
of music or voice.
