The package consists of bezel assembly, grille, rear enclosure, 8-inch coaxial two-way loudspeaker and internal line-matching transformer. The loudspeaker features waveguide coupled titanium coated dome tweeter. The loudspeaker utilizes 2nd order crossover network at 2.5kHz with comprehensive protection circuit to protect the network, woofer and tweeter drivers from excessive power levels. It utilizes a transformer that offers selection of 1.88 (70V only), 3.75, 7.5, 15 or 30W delivered to the loudspeaker system using either 70 or 100V lines or 8 Ohms 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 UL94V-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 provision for junction box fitting provides access to 4-pin terminal block that allows direct connection to the speaker with 12-gauge wire and provides pass-through to additional speakers. The model features 3-pin fire-safety rated input block. A tile bridge is included for safe suspension of the C8.2 ceiling systems in 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 complete system in wide range of different ceiling constructions.
