The Electro-Voice EVF-1152D/43-FG is a fully-weatherized, fiber-

glass-coated, high-power, two-way loudspeaker system that can be

used in a variety of applications where high-quality sound reinforce-

ment is required in a compact, lightweight package.

The EVF-1152D/43-FG utilizes the DH7N, a high-output 3” titanium

compression driver, coupled to a Constant Directivity™ 40° x 30°

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 equal-

ization for very smooth response in the vocal range, linear off-axis

response, and a protection circuit for long-term reliability.

The EVF-1152D/43-FG’s features make it ideal for many fixed-install

applications, including applications with full exposure to outdoor

elements. The trapezoidal enclosure is constructed of weather-resis-

tant birch, and coated with fiberglass for maximum protection from

extreme outdoor elements. The unique 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.

With seven horn patterns to choose from, along with an assortment

of low-frequency and subwoofer loudspeakers, you have the tools to

maximize flexibility of system design, no matter what the application

and budget. The innovative input panel provides a choice of Phoenix-

style connector (included in all standard models) or the ability to add

a dual NL4-type connector cover plate or gland-nut cover plate (for

weatherizing applications). An externally accessible jumper selects

passive or active operation. An available 70.7/100-V transformer

kit may be easily mounted to the input panel for use in distributed

systems. All these features give you the flexibility to address a large

range of venues, quickly and precisely supporting customer require-

ments with fewer items in inventory.
