Description
Introducing a family of advanced sound
reinforcement products for everyone who
desires the sound quality of Electro-Voice's
X-Array™ touring systems. X-Array
Install™ is the ideal choice for small-to-me-
dium array configurations and fixed instal-
lations of any size.
Inspired by the most demanded features of
EV's acclaimed X-Array™ touring systems,
the X-Array Install™ series incorporates a
potent combination of very high output,
medium- to long-throw "cells," and
Ring-Mode Decoupling (RMD™).
RMD™
RMD™ (Ring-Mode Decoupling) is the
same advanced technology built into the
X-Array™ touring series. RMD™ produces
substantially improved tonal character and
fidelity whether operated at low or extremely
high sound pressure levels. RMD™ attacks
time domain "ringing modes" at their
sources. Mechanical solutions resolve
mechanical issues, and acoustical solutions
address acoustical modes found in all sound
reinforcement systems. The combination of
each RMD™ technique provides improved
tonal character and fidelity at increasing drive
levels. The result is clear, even sound qual-
ity with vastly improved intelligibility.
Xi-1153/64 and Two-Element Line Array
These triamp-ready, three-way systems in a
unique two-element-line-array configuration
are designed for use in reverberant spaces.
One woofer flanks and works with the mid-
bass horn to form the line array, extending
vertical directivity control to below 200 Hz.
Such wide-bandwidth control and the me-
dium-Q (60° x 40°) pattern provide superior
direct-to-reflected SPL ratios and improved
system intelligibility, and suppress feedback
below arrays.
When optimum directivity control is re-
quired, the Xi-1153/64 with a single 15-inch
woofer (EVX-155), should be used. The
12-inch mid-bass driver features RMD™
coupled with a 60° x 40° vertical horn.
The high-frequency system uses a DH6 large-
format compression driver with a rotatable
60° x 40° horn. It is coaxially mounted, asym-
metrically positioned and fully "shrouded" to
preserve mid-bass wave-front detail. For
extended-bass/subbass, the Xi-1153/64 may
be used with the Xi-1191 subwoofer.
Applications
The Xi-1153/64 is ideally suited for high-
level, high-fidelity applications. The ex-
tended capabilities, of the system, particu-
larly the low-frequency capability and verti-
cal polar control allow the system to be used
very successfully without the need of a sub-
woofer. For application of low-frequency
sound pressure levels coupled with very ac-
curate vocal reproduction, the Xi-1153/64 may
be coupled with the Electro-Voice Xi-1191
subwoofer.
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
bounadries of the loudspeakers are also per-
formed for an extra measure of reliability.
The Xi-1153/64 systems are rated per ANSI/
EIA RS426-A 1980 Loudspeaker Power
Rating, Full Range Test, which uses a
shaped-random-noise signal to simulate
typical music to test the mechanical and
thermal capabilities of the loudspeakers.
