General Description:

The Electro-Voice EVF-1122D/99-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-1122D/99-FG utilizes the DH7N, a high-output 3" titanium
compression driver, coupled to a Constant Directivity™ 90° x 90°
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 equal-
ization for very smooth response in the vocal range, linear off-axis
response, and a protection circuit for long-term reliability.
The EVF-1122D/99-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-
resistant birch, and coated with fiberglass for maximum protection
from extreme outdoor elements. The unique acoustic and rigging de-
sign 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.
