The Electro-Voice EVID C 8.2HC 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" coax two-way loudspeaker with waveguide coupled titanium coated dome tweeter and internal line-matching transformer.
The C 8.2HC 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 C 8.2HC 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.
