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.

5. The distortion at any given frequency may be found by graphically taking the dif­ference between the fundamental and har­monic, and adding the number of decibels which the harmonic has been raised on the graph and apply the formula: percent dis­tortion = 100 x 10
(-difference in dB/20)
