Description

The Electro-Voice EVI-15 full-range loud-

speaker is a factory assembled system featur-

ing a small-format Vari Intense

®

 horn and a

15-inch direct radiator in a vented enclosure.

The EVI-15 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-15 consists of a proprietary cast-

frame 381-mm (15-in.) high-power, long-

excursion  low-frequency driver mounted

within a vented chamber of 3.4 cubic feet,

optimally tuned to provide unequalized low-

frequency response to below 50 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.

Electrical 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 pas-

sive crossover featuring self-setting

tweeter protection and asymetric acous-

tic slopes with passive lobe steering for

uniform coverage throughout the cross-

over 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 sus-

pension of the EVI-15.  There are two hang-

ing options recommended.  The optional U-

Bracket hanging kit, MB-EVI15 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 located on the lower back of the en-

closure.  The second option is available us-

ing the two T-nut locations on the front top

of the enclosure as well as the pull-up loca-

tion 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 sys-

tem may then be hung individually or in an

array.  Please read the included Applica-

tions Guide for more information on

mounting methods and installation tac-

tics.  The system may be ordered in a tex-

tured black or white paint which can be

painted to complement any interior.  The grille

is constructed from a sturdy 16-gauge me-

dium-gloss black or white powder-coated steel

and may be painted or covered with cloth to

match the enclosure.

The EVI-15 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.
