The Electro-Voice 309 series loudspeaker systems are two-way loudspeakers with 8-inch low-frequency cones and high temperature voice-coil assemblies coaxially mounted with wide-dispersion cone tweeters. The dual magnet construction allows each speaker to be structurally, magnetically, electrically and mechanically independent of the other.
The 309-8TWB is features a 70.7/100-V line transformer that offers <1 dB insertion loss and a selection of 1-, 2-, 4- and 8-W taps and a pre-mounted white grille. These components are designed to work together as a complete system of in-ceiling loudspeakers and accessories. They provide wide dispersion, high-efficiency, high- maximum output, ease of installation and wide-range reproduction of music or voice.
