Description

The Electro-Voice EVI-12 full-range loud-

speaker is a factory assembled system fea-

turing a small-format Vari Intense

®

 horn and

a 12-inch direct radiator in a vented enclo-

sure.  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 com-

ponent in most multi-way loudspeaker sys-

tems.

The EVI-12 consists of a proprietary cast-

frame 305-mm (12-in.) high-power, long-

excursion  low-frequency driver mounted

within a vented chamber of 2.5 cubic feet,

optimally tuned to provide unequalized low-

frequency 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

6

 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/long-

throw horn combination, reducing the ma-

terial and labor costs of an installation. Elec-

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 pas-

sive lobe steering for uniform coverage

throughout the crossover region. The en-

closure 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 pro-

vided for safe suspension of the EVI-12.

There are two hanging options recom-

mended.  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 en-

closure 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 en-

closure as well as the pull-up location on the

lower back of the enclosure.  The EBK-1 kit

of three forged shoulder eyebolts is avail-

able 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 comple-

ment 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

®

 loud-

speaker is the ideal system whenever high-

output full-frequency-range material must be

reproduced in churches, gymnasiums,

auditoriums, hotels and civic centers.
