The Electro-Voice EVF-1122S/64 is a high power,
two-way front loaded loudspeaker system that can be
used in a variety of applications where high quality
sound reinforcement is required in a compact,
lightweight package.
For high frequencies, the EVF-1122S/64 utilizes the
ND2B high output 2-inch titanium compression driver,
coupled to a rotatable Constant Directivity
60° x 40° waveguide. For low frequencies, the
SMX2121 12-inch 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 an HF protection circuit for long
term reliability.
The EVF-1122S/64 features make it ideal for many
fixed-install applications. The trapezoidal enclosure is
constructed out of weather-resistant birch and coated
with EVCoat for enhanced durability. For protection
against outdoor elements, weatherized versions are
available (PI and FG). The enclosure is built with 22
M10 suspension points; 20 for single hang (four (4)
shoulder eyebolts included) or cluster arrays (optional
HRK or VRK kits) and two (2) for single hang with a
U-bracket (optional EVF-UB).
The innovative input panel provides Phoenix-style
connectors (included in all models) and a dual gland
nut cover plate (CDG included in PI and FG models).
For convenience in temporary installation you may add
a dual NL4 type connector cover plate (CDNL4). An
external easy to access jumper card is provided with
each loudspeaker to assist you in the selection of
passive (standard shipping configuration) or biamp
operation. An available 70.7/100 Volt internal
transformer kit (TK-150) may be easily mounted to the
input panel for use in distributed systems.
No matter what the application and budget, all these
features provide you with the tools to increase
flexibility during system design to meet and support
your customer’s requirements with fewer items in
inventory.
EVF and EVH loudspeakers feature precise acoustics
and rigging design for easy to configure vertical and
horizontal clusters as part of the solutions provided in
the EV innovation family.
