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.
