Description

The X-Array™ product line represents im-portant advancements in concert-sound-reinforcement technology. The designgoals called for the highest acoustic out-put capability with the highest fidelity inlightweight, compact enclosures that wereeasy to array. The development began witha clean sheet of paper and took an inte-grated approach. The individual loud-speaker drivers, horns, enclosures, rigginghardware and system configurations weredesigned from the ground up specificallyfor 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 hornloaded with one driver in each frequencyband, and the HF horn/driver combinationis mounted coaxially inside the mid-basshorn. The mid-bass and high-frequencysections are identical to that of the full-size Xn X-Array™ system. The horns anddrivers were designed as part of the Xcndevelopment and represent a step forwardin state-of-the-art loudspeaker design interms of high acoustic output with lowdistortion and low power compression.Electro-Voice engineers developed anew technology dubbed Ring-Mode

Decoupling (RMD™) to substantially im-prove clarity and intelligibility by reduc-ing both linear and nonlinear resonancemodes that color the sound.

The high-frequency driver in the Xcn isthe ND5, which is a 3.56-mm (1.4-in.) exithigh-frequency compression driver thatfeatures a powerful neodymium motorstructure that was optimized for maximumefficiency and reduced power compression.A new 76.2-mm (3.0-in.)-diameter titaniumdiaphragm assembly provides increased in-stantaneous peak output capability andreduced dome breakup. The ND5 ismounted on a 60° x 40° rotatable constant-directivity horn. This combination resultsin substantially improved vocal clarity andpresence with a smooth response through-out the vocal range up to 20,000 Hz. Thehorn 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 theND12A, which is a 30.5-mm (12-in.) mid-bass driver that features a powerful newneodymium motor structure that was opti-mized for maximum horn-loaded efficiencyand reduced power compression. A newKevlar®-reinforced cone assembly pro-vides a smooth response with reducedcone break up. The ND12A is mounted ona 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 combinationresults in improved vocal intelligibility andclarity with a smooth response from thelower-to-mid vocal range.

Ring-Mode Decoupling, (RMD™) is atechnique 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 veryfundamental problem. It has long been rec-ognized that two different loudspeakersystems can sound different even thoughthey both may be equalized to have thesame frequency response. This differenceis due to a variety of resonances, or ringmodes, that color the sound. Although thisringing may be very low in level comparedto the program material, it is still audible.The source of these resonances may bemechanical or acoustical in nature or a com-bination of both. In addition, they may belinear or nonlinear, resulting in their char-acter changing with level. Furthermore,these ring modes may be aggravated whenmultiple loudspeaker enclosures are as-sembled into arrays. The result is a colora-tion that decreases intelligibility and clar-

ity with the nature of that coloration vary-ing with level. Often, the listener perceivesthat coloration as imbalance in the fre-quency response, and will attempt to elec-tronically adjust the system to restore thespectral balance. However this electronicequalization has the negative effect ofchanging the program material itself.

Ring-Mode Decoupling (RMD™) ad-dresses mechanical resonances with me-chanical solutions, and acoustical reso-nances with acoustical solutions. In theXcn development, RMD™ was applied atevery level – to the individual mid-bassand high-frequency drivers, the mid-bassand high-frequency horns, the mid-basschamber, the interaction between the mid-bass and high-frequency bands and theinteraction between multiple enclosures.

The design process included, for example,the driver diaphragm, cone, suspensionand phase-plug geometry and materials,horn geometry and materials, enclosure ge-ometry and materials, absorptive materi-als, etc. The result is a dramatic improve-ment in clarity and with a much more neu-tral sound (a lack of coloration), with theloudspeaker system maintaining its sonicintegrity from the very-lowest sound-pres-sure levels, to the very-highest sound-pres-sure levels. This means that the front-of-house engineer will not have to retune theEQ and level settings as the SPL is in-creased throughout the show. This alsomeans that the sound-system performancewill remain consistent in different array con-figurations and from venue to venue.

The X-Array™ systems utilizes a uniquerigging system. A hinge assembly is usedto link cabinets together at their rear cor-ners, while wire-rope/fitting assemblies areused at the front to adjust the relative anglebetween systems. (See the Flying the X-Array™ Systems section for more details.)

The Xcn utilizes the half-size X-Array™enclosure shell, which is identical to thatof the Xcb bass system. They have thesame footprint and rigging as the full-sizeX-Array™ systems; however, the heightof the compact systems is approximatelyhalf that of the full-size systems.

The durable Xcn enclosure is constructed

of 18-mm, 13-ply birch plywood and has awear-resistant black, textured paint finish.The system is trapezoidal, forming an

18° wedge, and includes a heavy-dutysteel grille with a water-resistant charcoal-gray foam interlining. The enclosure fea-tures vinyl bumper pads on the front cor-ners and feet on the bottom to resist wear.

A variety of accessories are available forthe X-Array™ loudspeaker systems, in-cluding rigging hardware, dollies, covers,electronic crossovers, amplifier racks andspeaker cabling. Consult the X-Array™ Ac-

cessories section for a complete listing theavailable accessories.

Applications

The X-Array™ loudspeaker systems weredesigned for optimal performance in bothconcert-sound and permanent-installationapplications where studio-monitor soundquality is required at concert-sound lev-els. The X-Array™ loudspeaker systemswork well individually, in small arrays andin large arrays. The high-acoustic outputfrom these compact, lightweight systemsprovide the highest acoustic-power-to-weight ratio, the highest acoustic-power-to-frontal-area ratio, and the highest acous-tic-power-to-bulk-volume ratio in the in-dustry. That means that X-Array™ sys-tems will be considerably smaller and lightercompared to competitive systems havingequivalent acoustic output.

The 60° x 40° coverage pattern of the Xcnmakes it ideal for sound-reinforcement ap-plications with short- to medium-throw

requirements. With its response from 125-20,000 Hz, the Xcn is recommended for mid-bass/high-frequency applications, andshould be used with an X-Array™ bassbox (like the Xb, Xcb or Xds) for full-rangeperformance. The Xcn may be used indi-vidually or in multiples to construct arrays.In addition, the Xcn may be used with theMB/HF- or LF/MB/HF X-Array™ loud-speaker systems (like the Xf, Xn or Xcn) toconstruct large full-range arrays. The Xcnenclosure is identical to that of the otherhalf-size X-Array™ systems (like the Xcb).The footprint of the half-size X-Array™enclosures is identical to that of the full-

size X-Array™ systems (like the Xn, Xfand Xb), as is the rigging hardware, mak-ing array integration easy whether flyingor stacking. The rotatable horn pattern of-fers tremendous flexibility to tailor the pat-tern to the application. For example, the60°H x 40°V orientation would be wellsuited for front-of-house, front-fill and side-fill applications while the 40°H x 60°V ori-entation would be well suited for down-fillapplications.

The Xcn is a two-way active system thatrequires an active electronic crossover.Both the Electro-Voice Dx38 and KlarkTeknik DN8000 digital crossovers are rec-ommended for signal control. (See theCrossover, Equalization and Signal De-lay Controller section.) The Electro-VoiceP3000 amplifier is recommended for pow-ering the Xcn. (See the Amplifier Recom-mendations section.)

Power-Handling Capabilities

The Xcn systems are rated as per the“ANSI/EIA RS-426-A Loudspeaker PowerRating, Full Range Test,” which uses ashaped-random-noise signal to simulatetypical music to test the mechanical andthermal capabilities of the loudspeakers.A digital crossover was used to providethe appropriate filtering and equalization.The test parameters are as follows:

Xcn loudspeakers may be paralleled withother Xcn systems as long as the amplifi-ers can drive the lower impedances. Tomaintain a sufficient damping factor withlong cable runs, amplifier loads of fourohms per channel are recommended. TheElectro-Voice P3000 amplifiers are ideal forpowering the X-Array™ systems.

Crossover, Equalization and SignalDelay Controller

The Xcn is a two-way active loudspeakersystem requiring an active crossover,equalization and signal delay controller.For basic applications, the Electro-VoiceDx38 2-in/4-out controller is recommended.For more sophisticated applications, theKlark Teknik DN8000 2-in/ 5-out controlleris recommended. Linkwitz-Riley crossoverfilters with a minimum slope of 24-dB peroctave at 125 Hz and 1,760 Hz are recom-mended. Both the Dx38 and the DN8000offer appropriate filtering, equalization andsignal delay capabilities to provide opti-mum performance of the X-Array™ loud-speaker systems. Digital parameter settingsfor both controllers are available uponrequest.

Electrical Connection and SystemWiring

Two paralleled Neutrik 8-pin Speakon®

connectors are used for electrical connec-tion to the Xcn loudspeakers with the fol-lowing pin assignments:

HF: Pins 4 Paralleled

MB: Pins 3 Paralleled

The Xcn wiring diagram is shown in Fig-ure 7. Since the connectors are paralleled,it does not matter which connector is usedas the input or output when paralleling Xcnsystems. Although Pins 1 and 2 are notused by the Xcn systems, they are paral-leled on the input panel. This allows an X-Array™ bass box (like the Xb or Xcb –

which use Pins 1 and 2, but not Pins 3 and4) to be paralleled with an Xcn, allowing alleight conductors to be used with a singlecable run to the amplifiers. Note that whenfour Xcn systems are jumped from one toanother, the amplifier home-run cable willhave four high-frequency drivers on Pins4 (for a 4-ohm load) and four mid-bass driv-ers on Pins 3 (for a 4-ohm load).

Flying the X-Array™ Systems

The X-Array™ loudspeaker systems allutilize the same rigging hardware and havethe same structural strength ratings. Thus,different systems may be mixed in an arrayto achieve the best acoustic results. Therigging system allows for the smallest pos-sible spacing between adjacent enclosures,and utilizes quick-release rigging fittingsfor fast installation and tear down.

When flown, the X-Array™ enclosures arelinked together by two removable hingeson the rear of the enclosures at the top andbottom. This arrangement enables the en-closures to pivot vertically from the rearcorners. The relative vertical angle betweenadjacent enclosures is adjustable and setby two removable rigging straps on thefront of the enclosures at the top and bot-tom. Both the rear rigging hinges and thefront rigging straps are installed when en-closures are sitting on top of one another.For ease of installation of the hinges andstraps, the enclosures self align using feetand cups mounted on the top and bottomof the enclosures. The relative horizontalangle between adjacent columns of loud-speakers is set by adjustable grids at thetop of the array (or by custom-building at-tachment supports in permanent-installa-tion applications where grids are not used).

The removable proprietary rear rigginghinges utilize all-steel construction and aresecured into a proprietary track assemblyon the enclosure (similar to the heavy-dutyaircraft L-track). The aluminum track is ex-truded as a single-piece track/angle-bracketassembly and ties into the top, bottom andrear of the enclosure. Metal bars inside theenclosure tie the top and bottom track/angle-bracket assemblies together, minimiz-ing the load applied to the wooden enclo-

sure. The rear extrusion will accommodatethe New Haven 32102-2 aircraft-typedouble-stud locking fitting instead of thehinge for applications requiring a lowerstrength rating.

The removable front strap assemblies uti-lize all-steel New Haven 32102-2 aircraft-type double-stud locking fittings and wirerope, and are secured into another propri-etary track similar to the heavy-duty air-craft L-track. The track is extruded as asingle-piece track/angle-bracket assemblythat ties into the front and side of the en-closure. The track/angle-bracket assemblyextends from the top to the bottom of theenclosure, eliminating the load applied tothe wooden enclosure.

A complete line of flying-hardware acces-sories is available for the X-Array™ loud-speaker systems including a grid, rigginghinges and rigging straps. The variety ofrigging hinges and front rigging strapsavailable include those for linking two en-closures together, securing the top enclo-sure in a column to a grid, and for pickingup the top enclosure in a column without agrid. Consult the X-Array™ Accessoriessection for a complete listing the availablerigging accessories.

The total weight of a column of X-Array™loudspeaker systems that may be sup-ported by the X-Array™ rigging systemvaries from 454-726 kg (1,000-1,600 lb) de-pending on the rigging configuration de-tails. An X-Array™ Flying Manual isavailable from Electro-Voice and is includedwith each X-Array™ system shipment. Themanual should be consulted for completestructural specifications and detailed in-structions for safely suspending and us-ing the X-Array™ systems.

Plotsof second and third harmonic distortionare shown referenced to the fundamental.

Figure 4 — DirectivityThe directivity index, D

i, and directivity fac-

tor, R , of the Xcn were measured with a

full- spherical measurement system as de-scribed in Figure 1.

Figure 6 — ImpedanceThe impedance of each frequency band ofthe Xcn was measured in an anechoic en-vironment.
