X-Array™ Loudspeaker Systems
0. INTRODUCTION
The X-Array™ product line represents important
advancements in concert-sound-reinforcement
technology. The design goals called for the high-
est 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 ap-
proach. The individual loudspeaker drivers, horns,
enclosures, rigging hardware and system configu-
rations were designed from the ground up specifi-
cally for this high-performance application. A brief
description of the X-Array™ product line is in-
cluded below. Consult the individual system engi-
neering data sheets for detailed specifications.
Xf: Far-field, two-way, MB/HF loudspeaker sys-
tem with a 40°H x 20°V coverage pattern. The
system has two ND12A 305-mm (12-in.) MB
drivers and two ND5-16 76-mm (3-in.) HF com-
pression drivers. The Xf utilizes the full-size
X-Array™ enclosure shell and the standard
X-Array™ flying hardware.
Xn: Near-field, three-way, LF/MB/HF loud-
speaker system with a rotatable 60° x 40° cover-
age pattern. The system has one EVX-180B
457-mm (18-in.) woofer, one ND12A 305-mm
(12-in.) MB driver and one ND5-16 76-mm (3-in.)
HF compression driver. The Xn utilizes the full-
size X-Array™ enclosure shell and the standard
X-Array™ flying hardware.
Xb: Bass loudspeaker system with two
EVX-180B 457-mm (18-in.) woofers. The Xb
utilizes the full-size X-Array™ enclosure shell
and the standard X-Array™ flying hardware.
Xds: Subwoofer loudspeaker system with two
EVX-180B 457-mm (18-in.) woofers. The Xds
utilizes the double-wide X-Array™ enclosure
shell and does not have flying hardware.
Xcn: Compact near-field, two-way, MB/HF loud-
speaker system with a rotatable 60° x 40° cover-
age pattern. The system has one ND12A 305-mm
(12-in.) MB driver and one ND5-16 76-mm (3-in.)
HF compression driver. The Xcn utilizes the half-
size X-Array™ enclosure shell and the standard
X-Array™ flying hardware.
Xcb: Compact bass loudspeaker system with
one 457-mm (18-in.) EVX-180B woofer. The Xcb
utilizes the half-size X-Array™ enclosure shell
and the standard X-Array™ flying hardware.
Numerous accessories are available to complete
an X-Array™ loudspeaker system, including rig-
ging hardware, digital electronic controllers,
power amplifiers, cables, racks, cases, dolly
boards and speaker covers. See

B. X-Array™ Rigging Accessories
for a list of
available accessories and where to purchase
them. See
Appendix A. Servicing the X-Array™
Rigging
for service information.
1. X-ARRAY™ RIGGING SYSTEM
1.1 Overview of the X-Array™ Flying System
The X-Array™ rear-hinge/front-strap flying system
makes constructing arrays easy, predictable and
repeatable. The hinging concept, combined with
the trapezoidal enclosures, allows arrays to be
constructed with the least possible spacing be-
tween enclosures.
A basic two-enclosure flying system is shown in
Figure 1 that illustrates the integral components
that make up a typical X-Array™ flying system.
All of the flying X-Array™ loudspeaker systems
utilize horizontal rigging-track hardware on the
back of the enclosure (at both the top and bottom)
and vertical rigging-track hardware on the front
of the enclosures (at both the left and right sides).
The rear rigging-hinge hardware provides the
