Description

The X-Array™ product line represents im-

portant advancements in concert-sound-

reinforcement technology. The design

goals called for the highest acoustic out-

put 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 inte-

grated approach. The individual loud-

speaker drivers, horns, enclosures, rigging

hardware and system configurations were

designed from the ground up specifically

for this high-performance application.

The Xcn is an active near-field, two-way,

MB/HF loudspeaker system with a rotat-

able 60° x 40° coverage pattern. The high-

frequency and mid-bass sections are horn

loaded with one driver in each frequency

band, and the HF horn/driver combination

is mounted coaxially inside the mid-bass

horn. The mid-bass and high-frequency

sections are identical to that of the full-

size Xn X-Array™ system. The horns and

drivers were designed as part of the Xcn

development and represent a step forward

in state-of-the-art loudspeaker design in

terms of high acoustic output with low

distortion and low power compression.

Electro-Voice engineers developed a

new technology dubbed Ring-Mode

Decoupling (RMD™) to substantially im-

prove clarity and intelligibility by reduc-

ing both linear and nonlinear resonance

modes that color the sound.

The high-frequency driver in the Xcn is

the ND5, which is a 3.56-mm (1.4-in.) exit

high-frequency compression driver that

features a powerful neodymium motor

structure that was optimized for maximum

efficiency and reduced power compression.

A new 76.2-mm (3.0-in.)-diameter titanium

diaphragm assembly provides increased in-

stantaneous peak output capability and

reduced dome breakup. The ND5 is

mounted on a 60° x 40° rotatable constant-

directivity horn. This combination results

in substantially improved vocal clarity and

presence with a smooth response through-

out the vocal range up to 20,000 Hz. The

horn and driver are nested inside the mid-

bass phase plug assembly to minimize in-

terference in the mid-bass band.

The mid-bass driver in the Xcn is the

ND12A, which is a 30.5-mm (12-in.) mid-

bass driver that features a powerful new

neodymium motor structure that was opti-

mized for maximum horn-loaded efficiency

and reduced power compression. A new

Kevlar

®

-reinforced cone assembly pro-

vides a smooth response with reduced

cone break up. The ND12A is mounted on

a mid-bass horn that has a coverage pat-

tern that transitions smoothly into the ro-

tatable 60° x 40° high-frequency pattern.

The mid-bass phase plug provides opti-

mal loading for the ND12A driver, deliver-

ing smooth response and extended effi-

ciency up to 2,000 Hz. This combination

results in improved vocal intelligibility and

clarity with a smooth response from the

lower-to-mid vocal range.

Ring-Mode Decoupling, (RMD™) is a

technique utilized and named by Electro-

Voice to describe a process used to im-

prove sound quality in loudspeaker sys-

tems. RMD™ offers a solution to a very

fundamental problem. It has long been rec-

ognized that two different loudspeaker

systems can sound different even though

they both may be equalized 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 com-

bination of both. In addition, they may be

linear or nonlinear, resulting in their char-

acter changing with level. Furthermore,

these ring modes may be aggravated when

multiple loudspeaker enclosures are as-

sembled into arrays. The result is a colora-

tion that decreases intelligibility and clar-
