The white EVF-1122D Single 12” 2-Way Full-Range Indoor Loudspeaker System from Electro-Voice is can be used in a variety of applications where high-quality sound reinforcement is required. It utilizes the high-output DH7N 3” titanium compression driver, coupled with a constant directivity 90° x 60° waveguide. The DVX3121A 12” woofer was developed using FEA optimization for motor, suspension, and electrical design to ensure very low distortion, high efficiency, and maximum intelligibility at high SPL. The crossover uses steep, 24-dB-per-octave slopes with equalization for smooth response in the vocal range, linear off-axis response, and a protection circuit for long-term reliability.
The loudspeaker system is enclosed in a 13-ply birch with EVCoat for protection from elements. The acoustic and rigging design allows for vertical and horizontal clusters to be built using any combination of loudspeakers from the entire EVF and EVH series. The input panel includes dual 4-pin 10 AWG Phoenix connectors. An externally accessible jumper selects passive or active operation.
