Electro-Voice X-Array Xw12 User Manual

Description
The Electro-Voice Xw12 full-range, two-
way, floor monitor loudspeaker system is part
of the Electro-Voice X-Array
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-
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
™
series and is 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.

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:
Low-Frequency Section:
P : 300 watts
E(MAX)
Test Voltages: 47.0-volts rms
94.0-volts peak
R (1.15 R ): 7.36 ohms
SR E
High-Frequency Section:
P : 75 watts
E(MAX)
Test Voltages: 28.0-volts rms
54.0-volts peak
R (1.15 R ): 10.5 ohms
SR E
