General Description: Technical Specifications:
The Electro-Voice® EVF-1122S/66 is a 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/66 utilizes the ND2B, a high output 2” titanium
compression driver, coupled to a Constant Directivity™ 60° x 60°
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/66 features make it ideal for many fixed install applications. The trapezoidal enclosure is constructed out of weather resistant birch, and coated with EVCoatTM for maximum protection from
the 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 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 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 with fewer items in inventory
and quickly support your customer’s requirements.
