309

The Electro-Voice® 309 series loudspeaker systems are two-way loudspeakers with eight-inch, low-frequency cones and high-temperature, coaxially mounted voice-coil assemblies with wide-dispersion cone tweeters. The dual-magnet construction allows each speaker to remain structurally, magnetically, electrically, and mechanically independent of the other. The 309-8A, 309-4T, and 309-8T use a single-section crossover network, centered at 3,000 Hz, which provides six dB of attenuation for the tweeter outside its operating range. 

These components are designed to work together as a complete system of in-ceiling loudspeakers and accessories. They provide wide dispersion, high-efficiency, maximum output, ease of installation, and wide-range reproduction of music or voice. WB versions come complete with a pre-mounted ceiling grille.
