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 309-4T utilize a single section crossover network, centered at 3,000 Hz, which provides 6 dB of attenuation for the tweeter outside its operating range. The 309-4T is provided with a 25/70.7/100-V line transformer that offers <1 dB insertion loss and a selection of 0.5-, 1-, 2- and 4-W taps. It is designed to work together as a complete system of in-ceiling loudspeakers and accessories. it provides wide dispersion, high efficiency, high- maximum output, ease of installation and wide-range reproduction of music or voice.
