The Electro-Voice® EVF-1122S/66 is a high power, 2-way loud-
speaker system that can be used in a variety of applications where 
high quality sound reinforcement is required in a compact, light-
weight 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 appli-
cations.  The trapezoidal enclosure is constructed out of weather re-
sistant birch, and coated with EVCoat

TM

 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.
