Description

The X-Array

™

product line represents impor-

tant advancements in concert-sound-rein-

forcement technology. The design goals

called for the highest-acoustic output capa-

bility 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-perfor-

mance application.

The Xf is an active far field, two-way,

MB/

HF loudspeaker system with a

40° H x 20° V

coverage pattern utilizing the

full-size X-Array

™

enclosure shell. The

high-frequency and mid-bass sections are

horn loaded with two drivers in each fre-

quency band, and the high-frequency

horn/driver combination is mounted coaxi-

ally

inside the mid-bass horn. The horns

and drivers were designed as part of the

Xf development and represent a step for-

ward in state-of-the-art loudspeaker de-

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 Xf is the

ND5 which is a 35.6-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 dia-

phragm assembly provides increased instan-

taneous peak output capability and reduced

dome breakup. The ND5’s are mounted on a

unique tandem pair of 40° H x 20° V con-

stant-directivity horns. This combination re-

sults in substantially improved vocal clarity

and presence with a smooth response

throughout the vocal range up to 20,000 Hz.

The horns and drivers are nested inside the

mid-bass phase plug assemblies to minimize

interference in the mid-bass band.

The mid-bass driver in the Xf is the ND12A,

which is a 30.5-mm (12-in.) mid-bass driver

that features a powerful new neodymium

motor structure that was optimized for maxi-

mum horn-loaded efficiency and reduced

power compression. A new Kevlar

-rein-

forced cone assembly provides a smooth re-

sponse with reduced cone break up. The

ND12A’s are mounted on a dual-throat mid-

bass horn that has a coverage pattern that

transitions smoothly into the 40° H x 20° V

high-frequency pattern. The mid-bass phase

plug provides optimal loading for the

ND12A driver, delivering smooth response

and extended efficiency up to 2,000 Hz. This

combination results in improved vocal in-

telligibility and clarity with a smooth re-

sponse from the lower-to-mid vocal range.

Ring-Mode Decoupling, (RMD

™

), is a tech-

nique utilized and named by Electro-Voice

to describe a process used to improve sound

quality in loudspeaker systems. RMD

™

offers 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 equalized to have the same frequency

response. This difference is due to a vari-

ety 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 mul-

tiple 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 colora-
