EVID C8.2HC Ceiling
8” Two-Way
Coaxial High-Ceiling
Loudspeaker System
General Description:
The Electro-Voice ® EVID C8.2HC is an 8" coaxial transducer
featuring an innovative waveguide (patent pending) that provides
directivity control to 1 kHz. It provides much better music fidelity
and speech intelligibility in spaces with high ceiling heights than
typical flush units are capable of. Its 75° coverage pattern
provides the same coverage area when used in a 21’ ceiling as a
typical flush mount mounted unit in an 8’ ceiling. This loudspeaker
system is a complete two-way ceiling loudspeaker package. The
package consists of a bezel/waveguide assembly, grille, rear
enclosure, 8-inch coax two-way loudspeaker with waveguide
coupled titanium coated dome tweeter and internal line-matching
transformer. The C8.2HC utilizes a transformer that offers a
selection of 7.5 (70-V only), 15, 30 or 60 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 of the
waveguide. 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, 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 C8.2HC ceiling system in a
drop ceiling that uses mineral wool, or other fiber-based ceiling
tiles. The 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 controlled dispersion, high-efficiency,
high-maximum output, ease of installation, and wide-range
reproduction of music or voice.
