Power-Handling Test

Electro-Voice components and systems are

manufactured to exacting standards to en-

sure reliability in continuous use in arduous

real-life conditions.  Besides utilizing indus-

try-standard power tests, extreme in-house

power tests which push the performance

boundaries of the loudspeakers are also per-

formed for an extra measure of reliability.

The XW12 systems are rated per ANSI/

EIA RS-426-A Loudspeaker Power Rating,

Full Range Test, which uses a shaped-ran-

dom-noise signal to simulate typical music

to test the mechanical and thermal capa-

bilities of the loudspeakers.  The Dx38 digi-

tal electronic unit was used to provide the

necessary crossover filters and equaliza-

tion during power testing. Specifically, the

Xw12 passes the ANSI/EIA RS-426-A

power test with the following test param-

eters:

tion.  The compression driver is coupled

to an 80º x 55º horn. This flat-front, constant-

directivity horn is based on the Electro-Voice

HP series, and is geometrically optimized for

performance from 1,250-20,000 Hz.

The XW12 is constructed of 18-mm void-

free, 3/4-inch 12-ply curved plywood shell

which is extremely rigid. The baffle and end

pieces are made from 18-mm 13-ply birch

plywood. This high-strength enclosure

is sprayed with a resilient, textured black

finish for a truly professional appearance.

The end-mounted, recessed handle makes

transportation relatively easy.

Applications

The XW12 loudspeaker system is ideal for

use as a professional stage touring or in-

stallation application floor monitor where ex-

tremely high power and low distortion, as

well as accurate vocal coverage and maxi-

mized intelligibility are required from a sys-

tem housed in a compact, low-profile enclo-

sure. Its symmetrical design will allow two

monitors to be placed head to head so that

the high-frequency horns are coupled for

high-level large stage applications. The

Xw12 and associated controller combina-

tions are recommended for applications re-

quiring full bandwidth down to 60 Hz.

Description

The Electro-Voice Xw12 full-range, two-

way, floor monitor loudspeaker system is part

of the Electro-Voice X-Array

 series and is

intended for high-level sound reinforcement

in fixed-installation and touring-sound

applications. The Xw12 is a full-range

biamped floor monitor speaker system which

may be used with the Electro-Voice Dx38

digital crossover, the Klark Teknik DN8000

or any high-quality, signal-controller system.

The Xw12 employs a custom-designed, 12-

inch woofer for low-frequency reproduc-

tion.  Designed as part of the Xw12 devel-

opment, this woofer uses a new cone mate-

rial to provide maximum internal damping.

This woofer also employs "DL" technology

which utilizes a Thermal Inductive Ring, (TIR

),

a nonmagnetic pole piece extension that con-

trols inductance and, most importantly, pro-

vides a major heat transfer path from the top

of the voice coil to minimize power compres-

sion. For high frequencies, the Xw12 uses the

DH6, a 1.4-inch-exit variant of the DH1A com-

pression driver designed as part of the Xw12

development. Its unique one-piece geometri-

cally optimized titanium dome and suspen-

sion combined with its unusually powerful

magnetic motor provide maximum efficiency

and precise control of the diaphragm mo-
