Description
The X-Array
portant advancements in concert-sound-reinforcement technology. The design goals
called for the highest acoustic output capability with the highest fidelity in lightweight,
compact enclosures that were easy to array.
The development began with a clean sheet
of paper and took an integrated approach.
The individual loudspeaker drivers, horns,
enclosures, rigging hardware and system
configurations were designed from the
ground up specifically for this high-performance application.
The Xds is a manifolded, vented-box subwoofer system utilizing two 457-mm (18-in.)
woofers in the double-wide X-Array
sure shell. The enclosure has been optimized
for maximum subwoofer-frequency output.
The two woofers face each other in a manifold chamber at the center of the enclosure.
This manifolding technique (U.S. Patent
Number 4,733,749) increases the acoustic
loading, resulting in increased low-frequency efficiency (at slightly above box tuning) and reduced distortion compared to
conventional direct-radiating designs. The
woofers were designed as part of the Xds
development and represent a step forward
in state-of-the-art loudspeaker design in
™
product line represents im-
™
enclo-
terms of high acoustic output with low distortion and low power compression.
Electro-Voice engineers developed a new
technology dubbed Ring Mode Decoupling
™
(RMD
intelligibility by reducing both linear and
nonlinear resonance modes that color the
sound.
The low-frequency driver in the Xds is the
EVX-180B. An improved version of the industry-standard EVX-180A high-excursion
467-mm (18-in.) woofer that has distinguished itself as an industry standard for
high-power, low-frequency reproduction.
During the X-Array
mal conduction of the motor was improved
and the suspension was redesigned, giving
the EVX-180B even lower power compression and a longer mechanical lifetime. In the
Xds, the woofers are manifolded in a vented
enclosure optimized for maximized subwoofer output from 30-160 Hz with minimized distortion.
Ring Mode Decoupling, (RMD
nique utilized and named by Electro-Voice
to describe a process used to improve sound
quality in loudspeaker systems. RMD
fers a solution to a very fundamental problem. It has long been recognized that two
different loudspeaker systems can sound different even though they both may be equal-
) to substantially improve clarity and
™
development, the ther-
™
), is a tech-
™
of-
ized to have the same frequency response.
This difference is due to a variety of resonances, or ring modes that color the sound.
Although this ringing may be very low in
level compared to the program material, it is
still audible. The source of these resonances
may be mechanical or acoustical in nature,
or a combination of both. In addition, they
may be linear or nonlinear, resulting in their
character changing with level. Furthermore,
these Ring Modes may be aggravated when
multiple loudspeaker enclosures are assembled into arrays. The result is a coloration that decreases intelligibility and clarity,
with the nature of that coloration varying
with level. Often, the listener perceives that
coloration as imbalance in the frequency response, and will attempt to electronically
adjust the system to restore the spectral balance. However this electronic equalization
has the negative effect of changing the program material itself.
Ring Mode Decoupling (RMD
mechanical resonances with mechanical solutions, and acoustical resonances with
acoustical solutions. In the Xds development,
™
RMD
was applied at every level – to the
individual low-frequency drivers, the lowfrequency enclosure chambers and the interaction between multiple enclosures. The design process included, for example, the driver

) addresses
Xds Double Subwoofer System
cone, suspension geometry and materials,
enclosure geometry and materials, absorptive materials, etc. The result is a dramatic
improvement in clarity and with a much more
neutral sound (a lack of coloration) with the
loudspeaker system maintaining its sonic
integrity from the very-lowest sound pressure levels to the very-highest sound pressure levels. This means that the front-ofhouse engineer will not have to retune the
EQ and level settings as the SPL is increased
throughout the show. This also means that
the sound-system performance will remain
consistent in different array configurations
and from venue to venue.
The Xds utilizes a double-wide X-Array
Xds Double Subwoofer System
enclosure shell. The height of the Xds is identical to the standard, full-size X-Array
closures (like the Xf, Xn and Xb); however
the footprint matches that of two standard
X-Array™ enclosures sitting side by side
with their sides parallel. Thus, two standard
X-Array
™
enclosures (like the Xf, Xn, Xcn
or Xb) may be stacked on top of the Xds.
The Xds does not have rigging hardware for
flying.
The durable Xds enclosure is constructed of
18-mm, 13-ply birch plywood and has a
wear-resistant black, textured paint finish.
The system is trapezoidal, forming a 36°
wedge and includes a heavy-duty steel grille
with a water-resistant charcoal-gray foam interlining. The enclosure features vinyl
bumper pads on the front corners to and feet
on the bottom to resist wear.
A variety of accessories are available for the
X-Array
™
loudspeaker systems, including
rigging hardware, dollies, covers, electronic
crossovers, amplifier racks and speaker cabling. Consult the X-Array
™
Accessories sec-
tion for a complete listing of the available
accessories
Applications
The X-Array
™
loudspeaker systems were designed for optimal performance in both concert-sound and permanent-installation applications where studio-monitor sound quality
is required at concert-sound levels. The X-
™
Array
loudspeaker systems work well individually, in small arrays and in large arrays. The high acoustic output from these
™
en-
compact, lightweight systems provide the
highest acoustic-power-to-weight ratio, the
highest acoustic-power-to-frontal-area ratio,
and the highest acoustic-power-to-bulk-volume ratio in the industry. That means that
X-Array
™
systems will be considerably
smaller and lighter compared to competitive
systems having equivalent acoustic output.
With its response from 32-200 Hz, the Xds
is recommended for subwoofer and low-frequency applications where extremely high
levels of bass are required. Specifically, the
Xds has been optimized to provide subwoofer reinforcement for all of the X-Ar-
™
ray
™
loudspeaker systems. Typically , the Xds
would be crossed over to provide subwoofer
reinforcement from 80 Hz and below in parallel with the full-range systems (made up
of Xf, Xn, Xcn, Xb and Xcb systems that
cover 40 Hz and above). However, the Xds
may be crossed over at 125 Hz and used as a
combination subwoofer/low-frequency system in place of or in addition to the standard
low-frequency systems (like the Xb and
Xcb). The Xds may be used individually or
in multiples to construct subwoofer/low-frequency arrays, or may be used with the fullrange X-Array
™
systems to construct fullrange, large-scale arrays. The double-wide
Xds enclosure footprint matches that of two
standard X-Array
™
enclosures sitting side by
side with their sides parallel, allowing two
standard, full-size systems to be stacked on
top of the Xds. The Xds does not have flying hardware and is intended for stacking
only. The Xds would be well suited for frontof-house, front-fill, and side-fill applications.
The Xds is intended to be used with other
™
X-Array
systems for a full-range response
as an active system that requires an active
electronic crossover. Both the Electro-Voice
Dx38 and Klark Teknik DN8000 digital
crossovers are recommended for signal
control. (See the Crossover, Equalization
and Signal Delay Controller section.) The
Electro-Voice P3000 amplifier is recommended for powering the Xds. (See the
Amplifier Recommendations section.)
Power-Handling Capabilities
The Xds systems are rated as per the “ANSI/
EIA RS-426-A Loudspeaker Power- Rating,
Full-Range Test,” which uses a shapedrandom-noise signal to simulate typical
music to test the mechanical and thermal
capabilities of the loudspeakers. A digital
crossover was used to provide the appropriate filtering and equalization. The test
parameters are as follows:
Subwoofer Section (Pins 1 and 2 paralleled):
P
: 1,200 watts
E(MAX)
Test Voltage: 58.7-volts rms
117.4-volts peak
(1.15RE): 2.88 ohms
R
SR
Amplifier Recommendations
Power amplifiers with the following ratings
are recommended for use with the Xds loudspeaker systems:
SUB: 800 watts per channel
into 8 ohms
93-volts rms short term
132-volts peak
Xds loudspeakers may be paralleled with
other Xds systems as long as the amplifiers
can drive the lower impedances. To maintain a sufficient damping factor with long
cable runs, amplifier loads of four ohms per
channel are recommended. The ElectroVoice P3000 amplifiers are ideal for power-
™
ing the X-Array
systems.
Crossover, Equalization and Signal
Delay Controller
The Xds is intended to be used with other
™
X-Array
loudspeaker systems (like the Xf,
Xn, Xcn, Xb or Xcb) to construct full-range
arrays as an active system requiring an active crossover, equalization and signal delay controller. For basic applications, the
Electro-Voice Dx38 2-in/4-out controller is
recommended. For more sophisticated applications, the Klark Teknik DN8000 2-in/
5-out controller is recommended. LinkwitzRiley crossover filters with a minimum slope
of 24 dB per octave at 80-125 Hz are recommended, and infrasonic filter protection
at 34 Hz or higher with a minimum slope of
12-dB/octave is recommended. Both the
Dx38 and the DN8000 offer appropriate filtering, equalization and signal delay capabilities to provide optimum performance of
2

the X-Array™ loudspeaker systems. Digital parameter settings for both controllers
are available upon request.
Electrical Connection and System
Wiring
Two paralleled Neutrik 8-pin Speakon
®
connectors are used for electrical connection to
the Xds loudspeakers with the following pin
assignments:
SUB1: Pins 1 Paralleled
SUB2: Pins 2 Paralleled
The Xds wiring diagram is shown in Figure
7. Since the connectors are paralleled, it does
not matter which connector is used as the
input or output when paralleling Xds systems. Although Pins 3 and 4 are not used by
the Xds systems, they are paralleled on the
input panel. This allows an X-Array
™
MB/
HF box (like the Xf or Xcn– which use Pins
3 and 4, but not Pins 1 and 2) to be paralleled with an Xds, allowing all eight conductors to be used with a single cable run to
the amplifiers. Note that, when two Xds systems are jumped from one to another via the
input/output connections, the amplifier home
run cable will have two woofers on Pins 2
(for a 4-ohm load) and two woofers on Pins
1 (for a 4-ohm load).
Field Replacement
Normal service for the Xds requires only a
#2 Phillips screwdriver and a 3/16-inch hexkey wrench. The drivers may be accessed as
follows:
SUB: First remove the grille, then remove
the screws securing the hatch on the front of
the enclosure. Remove the screws securing
the 18-inch woofer and lift the woofer out
of the enclosure. In the event of failure, the
entire woofer must be replaced or reconed.
