General Description: Technical Specifications:
The Electro-Voice® EVF-1122S/94-FG is a fully-weatherized, fiberglass-coated, high power, 2-way 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-1122S/94-FG utilizes the ND2B, a high output 2” titanium
compression driver, coupled to a Constant Directivity™ 90° x 40°
waveguide. The SMX2121 12” woofer used FEA optimization for
motor, suspension, and electrical design for very low distortion,
high efficiency, and maximum intelligibility at high SPL levels. The
crossover uses steep 24 dB/octave slopes with equalization for
very smooth response in vocal range, linear off-axis response, and a
protection circuit for long term reliability.
The EVF-1122S/94-FG features make it ideal for many fixed install
applications, including applications with full exposure to outdoor
elements. The trapezoidal enclosure is constructed out of weather
resistant 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 & EVH Series,
with 7 horn patterns to choose from and an assortment of Low Frequency and subwoofer loudspeakers, it gives you the tools to maximize flexibility of system design, no matter what the application and
budget. The innovative input panel provides phoenix style connectors (included in all standard models) and gland nut cover plate (for
weatherizing applications). An externally accessible jumper selects
passive or active operation. An available 70.7/100 Volt transformer
kit simply mounts to the input panel for use in distributed systems.
All these features give you the flexibility to do a large range of venues in extreme enviroments with fewer items in inventory and quickly
support your customer’s requirements.
