The Electro-Voice EVF-1152D/64 is a high-power, twoway loudspeaker system that can be used in a variety of applications where high-quality sound reinforcement is required in a compact, lightweight package. The EVF-1152D/64 utilizes the DH7N, a high-output 3” titanium compression driver, coupled to a Constant Directivity 60° x 40° waveguide. The DVX3151A 15” 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 very smooth response in the vocal range, linear off-axis response, and a protection circuit for long-term reliability. The EVF-1152D/64’s features make it ideal for many fixed-install applications. The trapezoidal enclosure is constructed of weather-resistant birch, and coated with EVCoat for maximum protection from the elements. The unique acoustic and rigging design allows for vertical and horizontal arrays to be built using any combination of loudspeakers from the entire EVF and EVH series.
