The Electro-Voice EVID-EC3.1 is a complete 3-inch coaxial loudspeaker that offers excellent sound quality and outstanding reliability with first-class aesthetics.
The EVID-EC3.1 utilizes a transformer that offers a selection of 0.9 (70-V only), 1.88, 3.75, 7.5 or 15 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 is constructed from UL 94V-0 rated ABS. The rear enclosure is constructed from heavy gauge coated steel. The low-profile enclosure makes it easy to mount in very tight spaces. A side terminalcover provides access to a 4-pin terminal block that allows direct connection to the speaker with 12-gauge and 3.3 mm2-wire and provides pass through to additional speakers.
A mounting ring and a tile bridge are included for safe suspension of the EVID-EC3.1 ceiling systems in a drop ceiling that uses mineral wool, or other fiber-based ceiling tiles.
The wide range of EVID ceiling speakers has been designed to work together as a complete system in a variety of different ceiling constructions, and to be used in combination with other EVID surface-mount and in-wall speakers
