X-Array™: Ring-Mode Decoupling (RMD
™
), for
the best vocals you have ever heard. X-Array
™
marks the family of Electro-Voice loudspeaker
systems with Ring-Mode Decoupling. RMD
provides spectacularly clear vocals and smooth
midrange at all output levels. The X-Series
™
employs neodymium magnetics and a rigging
system designed and especially appropriate for
large, world-class touring arrays.

X-Array™Xi-Series™includes
special features that set the
systems apart.
Two- and three-element
line arrays: Extendedfrequency directivity
control
Using Merlin®signal
processing, “dipole”
and “tripole”
configuration of the Xi-1123,
Xi-2123, Xi-1153 and Xi-2153
provides vertical coverageangle control to as low as
125 Hz. More of the important
vocal range is aimed at the
absorptive audience instead of
the reflective room surfaces.
This helps increase intelligibility in reverberant spaces.
Reduced output below the
systems suppresses feedback
from microphones under the
loudspeakers.
Ring-Mode Decoupling
(RMD
™
): Breathtaking
vocal quality
Many acoustic
and mechanical
delayed resonances color the sound of
typical loudspeakers. EV
engineers have systematically
exposed these resonances and
suppressed them one by one.
We call this process Ring-Mode
Decoupling, or RMD
™
. The
resonances may not be measurable by conventional means,
and are typically many dB
below the desired signal. But
the human ear/brain combination is extremely sensitive to
such signals. RMD™gives a
quality of sound and degree of
clarity that audiences find
breathtaking.
Ring-Mode Decoupling
(RMD
™
): Level-independent
fidelity
In typical speaker
systems, as the
overall sound
pressure level is increased —
such as during a musical
performance — the delayed
resonances increase proportionally more than the primary
signal. This sends the sound
operator to the equalizers in
an attempt to "fix" the sound.
It is an ill-fated attempt since
changing the response of the
system cannot eliminate the
unpleasant resonances. RMD
™
suppresses acoustic and mechanical resonances at their source.
DH6 large-format driver:
Exceptional HF detail
at all SPL’s
All three-way and
virtually every
two-way system
in the series use a new largeformat compression driver
with RMD™. The titanium
diaphragm of the DH6 has
increased internal strength and
damping for unprecedented
HF clarity and resistance to
mechanical fatigue at very high
sound levels. The reduced
diaphragm-to-phase-plug
spacing applies acoustic
damping and maintains output
in the 10– to 20-kHz range.
Rotatable HF horns:
Coverage flexibility
Nearly every
Xi-Series™system
has a rotatable
HF horn. It is designed so the
intended coverage angle can
be maintained for vertical and
horizontal box orientations.
(The 100° x 60° Xi-2123 and
Xi-1123 also have rotatable
mid-bass horns.)
Rigging: L-tracks with
8:1 safety factor
Xi-Series™systems
(with the excep-
tion of the ultracompact Xi-1082 underbalcony) have dual L-tracks
top and bottom for two-point
suspension and aiming. The
L-track extrusions are tied
together by internal aluminum
bars which take the load
entirely away from the 13-ply
birch enclosures. As a result, a
safe and conservative suspension system is formed, one that
can be used with confidence.
Even in the largest
vertical arrays
recommended, an
8:1 safety factor is
maintained. The
L-tracks accept a
number of singleand double-stud
fittings (see engineering data
sheets and Xi-Series
™
Flying
Manual*).
this brochure adds models particularly appropriate for high-performance fixed installations.
Included are two- and three-element line-array
configurations, which increase intelligibility
and clarity in reverberant spaces through
extended-frequency directivity control.
Suspension hardware and magnetics are
optimized for permanent installation or
portable applications of small-to-medium size.
The Xi-Series

rings, under balcony and low-frequency

Many of the two-way systems also provide
superb performance on their own when room
acoustics and geometry are appropriate.
When performance demands are high,
Xi-Series

, in combination with Merlin

processing, will find ideal application in
performing arts centers, theaters, auditoriums,
houses of worship and regional touring.
Carrying handles on each
side of all Xi-Series

Specially designed
multigrip handles
are extremely
comfortable and can be
gripped from any angle,
making lifting much easier.
The large systems feature
four handles

the compact
two-way
systems have
two handles

The “tripole” configuration of the
Xi-2153/64 and Xi-2123/106 allows
output from the mid-bass horn to join
that of the spaced, dual low-frequency
sources and provide exceptional vocal
clarity in rever-berant spaces and
resistance to feedback beneath the
loudspeaker. This is accomplished
by extending a precisely controlled
radiation pattern to unusually low
frequencies.
