1.0 Introduction
The Electro-Voice EVF series is a group of compact two-way front-loaded full-range systems, available
with 12- or 15-inch woofers, augmented by low-frequency and subwoofer systems. EVF full-range sys-
tems are available in two versions. The "S" versions employ 400-watt SMX low-frequency transducers
and the ND2B medium-format, 1.4-inch exit/2-inch diaphragm compression driver. The "D" versions em-
ploy 500-watt DVX-A low-frequency transducers and the DH7N large-format, 1.4-inch exit/3-inch dia-
phragm compression driver. Both compression drivers have neodymium magnetic structures. In general,
the premium components in the "D" versions provide lower distortion and reduced power compression.
The EVH series is a group of larger two-way horn-loaded full-range systems. Both the "S" and "D" EVH
versions use SMX low-frequency transducers. The "D" versions substitute the DH7N large-format com-
pression driver for the ND2B medium-format driver.
All full-range systems utilize high-order crossover networks that seamlessly integrate the low-frequency
transducers with the high-frequency compression drivers, providing very low distortion and excellent fre-
quency response.
The EVF/EVH systems have many threaded rigging points that can be used with the supplied eyebolt kits
or optional suspension kits to easily create a number of horizontal or vertical cluster configurations. All
enclosures in their normal orientations (long axis vertical) share the same height, just over 30 inches (762
mm), promoting attractive clusters. Six coverage patterns, all rotatable, are available in each family, as
shown in Table 1a. The EVF-1121S and EVF-1151S low-frequency systems have integral low-pass filters
that allow paralleling them with up to two full-range systems, offering a cost-effective way to augment the
low-frequency output of EVF full-range systems.

Coverage patterns available in the EVF and EVH series (all rotatable)
The model number scheme denotes the number of woofers, the diameter of the woofers, the number of
band passes in the system, the woofer series used and, following a forward slash, the coverage pattern.
An example is the EVF-1122S/96, which has a single SMX series 12-inch woofer in a two-way configura-
tion and a 90° x 60° pattern. Another example is the EVF-1181S subwoofer, which has a single EVS-18S
18-inch woofer in a "one way" configuration and without a specific coverage pattern (essentially omnidi-
rectional in the very-low-frequency range in which it is usually operated).
