Introduction

EVC loudspeakers from Electro-Voice include five basic models. Three of them are two-way
trapezoidal loudspeaker systems that can be used in a wide variety of applications where wide
bandwidth, vertical and horizontal directivity control, and high efficiency are required in a
compact, cost-effective package. The EVC Variable Intensity model is a two-way design with a
unique compound waveguide that can evenly cover a defined rectangular audience area with
almost no variation in sound quality and minimal change in level. The 18” subwoofer will
complement any of the full-range systems. EVC loudspeakers are voiced so that they can be
seamlessly used in systems with other EV-Innovation models (EVF, EVH, and EVA).
The high frequency section of EVC loudspeakers comprises a single 1¼-inch pure titanium
dome compression driver directly coupled to a rotatable constant directivity waveguide that
delivers uniform pattern control and smooth, linear response. The low frequency section
employs a high-output woofer that was developed using state-of-the-art, computer-aided
optimization to provide low distortion, high efficiency, and maximum intelligibility at high
sound pressure levels. The passive crossover implements an enhanced fourth-order design
with slopes of greater than 24 dB per octave for smooth off-axis response and improved
definition through the critical vocal range. The subwoofer requires an external high-pass filter
or crossover; it is the only model without an internal passive filter network.
The EVC series is an extremely cost effective solution for many fixed-install applications. The
enclosures are constructed of 15-mm plywood and finished with EVCoat for enhanced
durability. The loudspeakers have been designed with multiple M10 rigging points as well as
attachment points for an optional U-bracket or multi mount style pan/tilt wall mount. There
are no bracket options for the subwoofer. All EVC loudspeakers accept wire gauges up to 10
AWG. The input panel also accepts optional covers with NL4-type connectors or weatherized
gland-nuts.
For 70V/100V operation, the input panel has an internal landing pad for mounting EV's high-
quality TK-150 audio transformer. When the transformer is installed, it engages EV's patented
Automatic Saturation Compensation (ASC), which preserves low frequency performance while
presenting a stable load to the amplifier - regardless of the number of speakers connected in
parallel. As a result, EVC loudspeakers - including the subwoofers - sound virtually identical,
whether they are used with a transformer or without.

Numbering scheme
The numbering scheme for EVC models is similar to that of other EV-Innovation loudspeakers.
It denotes the number and diameter of the woofers, the number of passbands, the coverage
pattern, level of weatherization, and the enclosure color. EVC speakers are available in black
or white and in your choice of robust EVCoat and partially weatherized versions. For example,
the EVC-1082-96PIW employs a single eight-inch woofer in a two-way configuration with a 90°
x 60° waveguide coverage pattern, and has a white, weatherized enclosure. Similarly, the
EVC-1181S-B uses a single 18” woofer to cover a single passband. In other words, it is a
subwoofer or low-frequency system in a black enclosure.

Finishes and colors available
EVC loudspeakers are finished in tough EVCoat. In addition, PI versions are rated for indirect
outdoor exposure in protected areas, such as under a roof overhang, and feature a stainless-
steel grille backed with acoustically-transparent hydrophobic cloth and a water-tight dual-
