XnX-Array™ Three-Way,LF/MB/HF System

Description

The X-Array™ product line represents impor-tant advancements in concert-sound rein-forcement technology. The design goalscalled 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 sheetof paper and took an integrated approach.The individual loudspeaker drivers, horns,enclosures, rigging hardware and systemconfigurations were designed from theground up specifically for this high-perfor-mance application.The Xn is an active near-field, three-way,semi-full-range LF/MB/HF loudspeakersystem with a rotatable 60° x 40° coveragepattern. The high-frequency and mid-basssections are horn loaded with one driver ineach frequency band, and the HF horn/driver combination is mounted coaxially in-side the mid-bass horn. The low-frequencysection has one driver in a slot-loaded en-closure. The woofer, horns and drivers weredesigned as part of the Xn developmentand represent a step forward in state-of-the-art loudspeaker design in terms of highacoustic output with low distortion andlow power compression. Electro-Voice en-gineers developed a new technologydubbed Ring-Mode Decoupling (RMD™)

to substantially improve clarity and intelli-gibility by reducing both linear and non-linear resonance modes that color thesound.The high-frequency driver in the Xn is theND5, which is a 3.56-mm (1.4-in.) exit high-frequency compression driver that featuresa powerful neodymium motor structure thatwas optimized for maximum efficiencyand reduced power compression. A new76.2-mm (3.0-in.)-diameter titanium dia-phragm assembly provides increased instan-taneous peak output capability and reduceddome breakup. The ND5 is mounted on a60° x 40° rotatable constant-directivity horn.This combination results in substantiallyimproved vocal clarity and presence with asmooth response throughout the vocal rangeup to 20,000 Hz. The horn and driver arenested inside the mid-bass phase plug assem-bly to minimize interference in the mid-bassband.The mid-bass driver in the Xn is the ND12A,which is a 30.5-mm (12-in.) mid-bass driverthat features a powerful new neodymiummotor structure that was optimized for maxi-mum horn-loaded efficiency and reducedpower compression. A new Kevlar®-rein-forced cone assembly provides a smoothresponse with reduced cone break up. TheND12A is mounted on a mid-bass horn thathas a coverage pattern that transitions

smoothly into the rotatable 60° x 40° high-frequency pattern. The mid-bass phase plugprovides optimal loading for the ND12Adriver, delivering smooth response and ex-tended efficiency up to 2,000 Hz. This com-bination results in improved vocal intelligi-bility and clarity with a smooth responsefrom the lower-to-mid vocal range.The low-frequency driver in the Xn is theEVX-180B, which is a high-excursion457-mm (18-in.) woofer that has distin-guished itself as an industry standard forhigh-power, low-frequency reproduction.The single slot-loaded, low-frequencywoofer in the Xn is less efficient than thehorn-loaded mid-bass- and high-frequencysections and, as such, can provide low-to-moderate levels of low-frequency repro-duction. For high levels of low-frequencyreproduction, addditional woofer systemsmust be added (Xb, Xcb and/or Xds). Dur-ing the X-Array™ development, the ther-mal conduction of the motor was improvedand the suspension was redesigned giv-ing the EVX-180B even lower power com-pression and longer mechanical lifetime.In the Xn, the woofer is slot loaded in asealed enclosure optimized for maximizedoutput from 48-160 Hz with minimized dis-tortion. Ring-Mode Decoupling, (RMD™)is a technique utilized and named byElectro-Voice to describe a process used

to improve sound quality in loudspeakersystems. 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 equalizedto have the same frequency response. Thisdifference is due to a variety of resonances,or ring modes, that color the sound. Althoughthis ringing may be very low in level com-pared to the program material, it is stillaudible. The source of these resonances maybe mechanical or acoustical in nature or acombination of both. In addition, they maybe linear or nonlinear, resulting in their char-acter changing with level. Furthermore, thesering modes may be aggravated when mul-tiple loudspeaker enclosures are assembledinto arrays. The result is a coloration that de-creases intelligibility and clarity with thenature of that coloration varying with level.Often, the listener perceives that colorationas imbalance in the frequency response,and will attempt to electronically adjustthe system to restore the spectral balance.However this electronic equalization has thenegative effect of changing the programmaterial itself.Ring-Mode Decoupling (RMD™) addressesmechanical resonances with mechanical so-lutions, and acoustical resonances withacoustical solutions. In the Xn development,RMD was applied at every level – to the in-dividual HF, MB and LF drivers, the HF andMB horns, the LF and MB enclosure cham-bers, the interaction between the HF, MB andLF frequency bands and the interactionbetween multiple enclosures. The designprocess included, for example, the driver dia-phragm, cone, suspension and phase-pluggeometry and materials, horn geometry andmaterials, enclosure geometry and materials,absorptive materials, etc. The result is a dra-matic improvement in clarity and with amuch more neutral sound (a lack of colora-tion), with the loudspeaker system maintain-ing its sonic integrity from the very-lowestsound-pressure levels, to the very-highestsound-pressure levels. This means that thefront-of-house engineer will not have toretune the EQ and level settings as the SPLis increased throughout the show. This alsomeans that the sound-system performance

will remain consistent in different array con-figurations and from venue to venue.The X-Array™ systems utilizes a unique rig-ging system. A hinge assembly is used to linkcabinets together at their rear corners, whilewire-rope/fitting assemblies are used at thefront to adjust the relative angle betweensystems. (See the Flying the X-Array™

Systems section for more details.)The durable Xn enclosure is constructed of18-mm, 13-ply birch plywood and has awear-resistant black, textured paint finish.The system is trapezoidal, forming an18° wedge, and includes a heavy-duty steelgrille with a water-resistant charcoal-grayfoam interlining. The enclosure featuresvinyl bumper pads on the front corners andfeet on the bottom to resist wear.A variety of accessories are available for theX-Array™ loudspeaker systems, includingrigging hardware, dollies, covers, electroniccrossovers, amplifier racks and speakercabling. Consult the X-Array™ Accessoriessection for a complete listing the availableaccessories.

Applications

The X-Array™ loudspeaker systems were de-signed for optimal performance in both con-cert-sound and permanent-installation appli-cations where studio-monitor sound qualityis required at concert-sound levels. TheX-Array™ loudspeaker systems work well in-dividually, in small arrays and in large ar-rays. The high-acoustic output from thesecompact, lightweight systems provide thehighest acoustic-power-to-weight ratio, thehighest acoustic-power-to-frontal-area ratio,and the highest acoustic-power-to-bulk-vol-ume ratio in the industry. That means thatX-Array™ systems will be considerablysmaller and lighter compared to competitivesystems having equivalent acoustic output.The 60° x 40° coverage pattern of the Xnmakes it ideal for sound-reinforcementapplications with short- to medium-throwrequirements. With its response from48-20,000 Hz, is recommended for full-range applications where a moderate levelof bass is required. Where very-high levelsof deep bass are required, maximum perfor-mance may be achieved with the addition ofan X-Array™ bass box (like the Xb, Xcb or

Xds). The Xn may be used individually orin multiples to construct arrays. In addi-tion, the Xn may be used with the MB/HFX-Array™ loudspeaker systems (like the Xfor Xcn) to construct large full-range arrays.The Xn enclosure shell and rigging are iden-tical to the other full-size X-Array™ systemsfor easy array integration. The rotatablehorn pattern offers tremendous flexibilityto tailor the pattern to the application. Forexample, the 60°H x 40°V orientation wouldbe well suited for front-of-house, front-filland side-fill applications while the40°H x 60°V would be well suited for down-fill applications.The Xn is a three-way active system that re-quires an active electronic crossover. Both theElectro-Voice Dx38 and Klark TeknikDN8000 digital crossovers are recom-mended for signal control. (See the Cross-over, Equalization and Signal Delay Con-troller section.) The Electro-Voice P3000amplifier is recommended for powering theXn. (See the Amplifier Recommendationssection.)

Power-Handling Capabilities

The Xn systems are rated as per the“ANSI/EIA RS-426-A Loudspeaker PowerRating, Full Range Test,” which uses ashaped-random-noise signal to simulate typi-cal music to test the mechanical and thermalcapabilities of the loudspeakers. A digitalcrossover was used to provide the appropri-ate filtering and equalization. The test param-eters are as follows:High-Frequency Section:

Amplifier Recommendations

Power amplifiers with the following ratingsare recommended for use with the Xn loud-speaker systems:

HF: 800 watts per channelinto 8 ohms93-volts rms short term132-volts peak

MB: 800 watts per channelinto 8 ohms93-volts rms short term132-volts peak

LF: 800 watts per channelinto 8 ohms93-volts rms short term132-volts peak

Xn loudspeakers may be paralleled withother Xn systems as long as the amplifierscan drive the lower impedances. To main-tain a sufficient damping factor withlong cable runs, amplifier loads of four ohmsper channel are recommended. TheElectro-Voice P3000 amplifiers are ideal forpowering the X-Array™ systems.

Crossover, Equalization and SignalDelay Controller

The Xn is a three-way active loudspeakersystem requiring an active crossover, equal-ization and signal delay controller. For basicapplications, the Electro-Voice Dx382-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, and subsonic filter protection at50 Hz or higher with a minimum slope of12-dB/octave is recommended in the low-frequency section. Both the Dx38 and theDN8000 offer appropriate filtering, equal-ization and signal delay capabilities to pro-vide optimum performance of the X-Array™

loudspeaker systems. Digital parametersettings for both controllers are availableupon request.

Electrical Connection and System Wiring

Two semiparalleled Neutrik 8-pin Speakon®

connectors are used for electrical connectionto the Xn loudspeakers with the following

pin assignments:HF: Pins 4 In / Pins 4 OutMB: Pins 3 / Pins 3 OutLF: Pins 1 In / Pins 2 Out

The Xn wiring diagram is shown inFigure 7. Note that one connector is specifi-cally labeled for input connection only andthe other for output connection only. Alsonote that Pins 1 In are connected to Pins 2Out, and Pins 2 In are connected to Pins 1Out. This facilitates wiring of multiple sys-tems with amplifiers. When four Xn systemsare jumped from one to another via theinput/output connections, the amplifier homerun cable will have four HF drivers onPins 4 (for a 4-ohm load), four MB driverson Pins 3 (for a 4-ohm load), two LF driverson Pins 2 (for a 4-ohm load) and two LF driv-ers on Pins 1 (for a 4-ohm load).

Flying the X-Array ™ Systems

The X-Array™ loudspeaker systems all uti-lize the same rigging hardware and have thesame structural strength ratings. Thus, dif-ferent systems may be mixed in an array toachieve the best acoustic results. The riggingsystem allows for the smallest possible spac-ing between adjacent enclosures, and uti-lizes quick-release rigging fittings for fastinstallation and tear down.When flown, the X-Array™ enclosures arelinked together by two removable hinges onthe rear of the enclosures at the top and bot-tom. This arrangement enables the enclo-sures to pivot vertically from the rear cor-ners. The relative vertical angles betweenadjacent enclosures is adjustable and set bytwo removable rigging straps on the front ofthe enclosures at the top and bottom. Boththe rear rigging hinges and the front riggingstraps are installed when enclosures are sit-ting on top of one another. For ease of in-stallation of the hinges and straps, the en-closures self align using feet and cupsmounted on the top and bottom of the en-closures. The relative horizontal angle be-tween adjacent columns of loudspeakers isset by adjustable grids at the top of the array(or by custom-building attachment supportsin permanent-installation applications wheregrids are not used).The removable proprietary rear rigginghinges utilize all-steel construction and are

secured 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-bracketaluminum assembly and ties into the top,bottom and rear of the enclosure. Metal barsinside the enclosure tie the top and bot-tom track/angle-bracket assemblies to-gether, minimizing the load applied to thewooden enclosure. The rear extrusion willaccommodate the New Haven 32102-2 air-craft-type double-stud locking fitting in-stead of the hinge for applications requir-ing a lower strength rating.The removable front strap assemblies uti-lize all-steel standard New Haven 32102-2aircraft-type double-stud locking fittingsand wire rope, and are secured into an-other proprietary track similar to the heavy-duty aircraft L-track. The track is extrudedas a single-piece track/angle-bracket as-sembly that ties into the front and side ofthe enclosure. The track/angle-bracket as-sembly extends from the top to the bottomof the enclosure, eliminating the load ap-plied to the 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 of rig-ging hinges and front rigging straps avail-able include those for linking two enclosurestogether, securing the top enclosure in a col-umn to a grid, and for picking up the topenclosure in a column without a grid. Con-sult the X-Array™ Accessories section for acomplete listing the available rigging acces-sories.The total weight of a column of X-Array™

loudspeaker systems that may be supportedby the X-Array™ rigging system varies from454-726 kg (1,000-1,600 lb) dependingon the rigging configuration details. AnX-Array™ Flying Manual is available fromElectro-Voice and is included with eachX-Array™ system shipment. The manualshould be consulted for complete structuralspecifications and detailed instructions forsafely suspending and using the X-Array™

systems.

Figure 5 — DistortionDistortion for the Xn was measured on axisin the far field in an anechoic environmentwith an input signal that would result in asound-pressure level of 115 dB at one meter.The Klark Teknik DN8000 digital electronicunit was used to provide the necessary cross-over filters, equalization and time delay. Afrequency spectrum typical of close-mikedrock music was employed. The sound pres-sure level was normalized for an equivalentone-meter distance. Plots of second and thirdharmonic distortion are shown referenced tothe fundamental.

Figure 4 — DirectivityThe directivity index, D

i, and directivity fac-

tor, R , of the Xn were measured with a full-

spherical measurement system as describedin Figure 1.

Figure 6 — ImpedanceThe impedance of each frequency band ofthe Xn was measured in an anechoic envi-ronment.
