Description

The Electro-Voice EVI-12 full-range loud­speaker is a factory assembled system fea­turing a small-format Vari Intense
a 12-inch direct radiator in a vented enclo­sure. The EVI-12 is intended to be used as a
stand-alone full-range system, but may also
be used as the mid-bass/high-frequency com­ponent in most multi-way loudspeaker sys­tems.

The EVI-12 consists of a proprietary cast­frame 305-mm (12-in.) high-power, long­excursion low-frequency driver mounted
within a vented chamber of 2.5 cubic feet,
optimally tuned to provide unequalized low­frequency response to below 45 Hz. The
high-frequency complement consists of a

25.4-mm (1.0-in.) exit compression driver
utilizing a new small-format Vari Intense
horn. Vari Intense® is a revolutionary pat-

ented

technology that throws a 6-to 10-dB
hotter signal to the back of the room. This
compensates for the drop in SPL over the
longer distance to the back of the room
(25 feet for the short throw and about 70 feet
for the long throw in a typical room). This
single horn replaces a short-throw/long­throw horn combination, reducing the ma­terial and labor costs of an installation. Elec-

horn and

trical connections to the system are made by
large screw terminals able to accept up to
12-gauge wire, mounted to an input panel
on the back of the enclosure. The system is
provided with a 2,000-Hz passive crossover
featuring self-setting tweeter protection
and asymetric acoustic slopes with pas­sive lobe steering for uniform coverage
throughout the crossover region. The en­closure is constructed from 19-mm (0.75-in.)
thick, thoroughly braced 7-ply birch plywood
lined with sound-absorbent glass wool. Five
3/8-16 shoulder-bolt hanging points are pro­vided for safe suspension of the EVI-12.
There are two hanging options recom­mended. The optional U-Bracket hanging
kit, MB-EVI12 is available for use with the
3/8-16 T-nut locations on the side of the en­closure along with a single pull-up strap lo-

®

cated on the lower back of the enclosure.
The second option is available using the two
T-nut locations on the front top of the en­closure as well as the pull-up location on the
lower back of the enclosure. The EBK-1 kit
of three forged shoulder eyebolts is avail­able if structurally rated 3/8-16 eyebolts
are not locally available. The system may
then be hung individually or in an array.

Please read the included Applications
Guide for more information on mounting

methods and installation tactics. The sys-

tem may be ordered in a textured black or
white paint which can be painted to comple­ment any interior. The grille is constructed
from a sturdy 16-gauge medium-gloss black
or white powder-coated steel and may be
painted or covered with cloth to match the
enclosure.

The EVI-12 full-range Vari Intense
speaker is the ideal system whenever high­output full-frequency-range material must be
reproduced in churches, gymnasiums,
auditoriums, hotels and civic centers.
