Description
The X-Array tant advancements in concert-sound rein­forcement technology. The design goals called for the highest acoustic output 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 integrated approach. The individual loudspeaker drivers, horns, enclosures, rigging hardware and system configurations were designed from the ground up specifically for this high-perfor­mance application. The Xn is an active near-field, three-way, semi-full-range LF/MB/HF loudspeaker system with a rotatable 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 low-frequency section has one driver in a slot-loaded en­closure. The woofer, horns and drivers were designed as part of the Xn development and represent a step forward in state-of­the-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
product line represents impor-
to substantially improve clarity and intelli­gibility by reducing both linear and non­linear resonance modes that color the sound. The high-frequency driver in the Xn is the ND5, which is a 3.56-mm (1.4-in.) exit high­frequency 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 instan­taneous 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 throughout the vocal range up to 20,000 Hz. The horn and driver are nested inside the mid-bass phase plug assem­bly to minimize interference in the mid-bass band. The mid-bass driver in the Xn 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 maxi­mum horn-loaded efficiency and reduced power compression. A new Kevlar forced cone assembly provides a smooth response with reduced cone break up. The ND12A is mounted on a mid-bass horn that has a coverage pattern that transitions

-rein-
smoothly into the rotatable 60° x 40° high­frequency 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 intelligi­bility and clarity with a smooth response from the lower-to-mid vocal range. The low-frequency driver in the Xn is the EVX-180B, which is a high-excursion 457-mm (18-in.) woofer that has distin­guished itself as an industry standard for high-power, low-frequency reproduction. The single slot-loaded, low-frequency woofer in the Xn is less efficient than the horn-loaded mid-bass- and high-frequency sections and, as such, can provide low-to­moderate levels of low-frequency repro­duction. For high levels of low-frequency reproduction, addditional woofer systems must be added (Xb, Xcb and/or Xds). Dur­ing the X-Array mal conduction of the motor was improved and the suspension was redesigned giv­ing the EVX-180B even lower power com­pression and longer mechanical lifetime. In the Xn, the woofer is slot loaded in a sealed enclosure optimized for maximized output from 48-160 Hz with minimized dis­tortion.

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 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 combination of both. In addition, they may be linear or nonlinear, resulting in their char­acter changing with level. Furthermore, these
Xn Three-Way, LF/MB/HF System
ring modes may be aggravated when mul­tiple 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 coloration as imbalance in the frequency response, and will attempt to electronically adjust the system to restore the spectral balance. However this electronic equalization has the negative effect of changing the program material itself. Ring-Mode Decoupling (RMD
) addresses mechanical resonances with mechanical so­lutions, and acoustical resonances with acoustical solutions. In the Xn development, RMD was applied at every level – to the in­dividual HF , MB and LF drivers, the HF and MB horns, the LF and MB enclosure cham­bers, the interaction between the HF , MB and LF frequency bands and the interaction between multiple enclosures. The design process included, for example, the driver dia­phragm, cone, suspension and phase-plug geometry and materials, horn geometry and materials, enclosure geometry and materials, absorptive materials, etc. The result is a dra­matic improvement in clarity and with a much more neutral sound (a lack of colora­tion), with the loudspeaker system maintain­ing its sonic integrity from the very-lowest sound-pressure levels, to the very-highest sound-pressure levels. This means that the front-of-house engineer will not have to retune the EQ and level settings as the SPL is increased throughout the show. This also means that the sound-system performance
will remain consistent in different array con­figurations and from venue to venue. The X-Array
systems utilizes a unique rig­ging system. A hinge assembly is used to link cabinets together at their rear corners, while wire-rope/fitting assemblies are used at the front to adjust the relative angle between systems. (See the Flying the X-Array Systems section for more details.) The durable Xn enclosure is constructed of 18-mm, 13-ply birch plywood and has a wear-resistant black, textured paint finish. The system is trapezoidal, forming an 18° wedge, and includes a heavy-duty steel grille with a water-resistant charcoal-gray foam interlining. The enclosure features vinyl bumper pads on the front corners and feet on the bottom to resist wear. A variety of accessories are available for the X-Array
loudspeaker systems, including rigging hardware, dollies, covers, electronic crossovers, amplifier racks and speaker cabling. Consult the X-Array
Accessories section for a complete listing the available accessories.
Applications
The X-Array
loudspeaker systems were de­signed for optimal performance in both con­cert-sound and permanent-installation appli­cations where studio-monitor sound quality is required at concert-sound levels. The X-Array
loudspeaker systems work well in­dividually, in small arrays and in large ar­rays. The high-acoustic output from these compact, lightweight systems provide the highest acoustic-power-to-weight ratio, the highest acoustic-power-to-frontal-area ratio, and the highest acoustic-power-to-bulk-vol­ume ratio in the industry. That means that X-Array
systems will be considerably smaller and lighter compared to competitive systems having equivalent acoustic output. The 60° x 40° coverage pattern of the Xn makes it ideal for sound-reinforcement applications with short- to medium-throw requirements. With its response from 48-20,000 Hz, is recommended for full­range applications where a moderate level of bass is required. Where very-high levels of deep bass are required, maximum perfor­mance may be achieved with the addition of an X-Array
bass box (like the Xb, Xcb or
Xds). The Xn may be used individually or in multiples to construct arrays. In addi­tion, the Xn may be used with the MB/HF X-Array
loudspeaker systems (like the Xf or Xcn) to construct large full-range arrays. The Xn enclosure shell and rigging are iden­tical to the other full-size X-Array
for easy array integration. The rotatable horn pattern offers tremendous flexibility to tailor the pattern to the application. For example, the 60°H x 40°V orientation would be well suited for front-of-house, front-fill and side-fill applications while the 40°H x 60°V would be well suited for down­fill applications. The Xn is a three-way active system that re­quires an active electronic crossover. Both the Electro-Voice Dx38 and Klark Teknik DN8000 digital crossovers are recom­mended for signal control. (See the Cross-
over, Equalization and Signal Delay Con­troller section.) The Electro-Voice P3000
amplifier is recommended for powering the Xn. (See the Amplifier Recommendations section.)
Power-Handling Capabilities
The Xn systems are rated as per the “ANSI/EIA RS-426-A 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. A digital crossover was used to provide the appropri­ate filtering and equalization. The test param­eters are as follows:

Amplifier Recommendations
Power amplifiers with the following ratings are recommended for use with the Xn loud­speaker systems:
HF: 800 watts per channel
into 8 ohms 93-volts rms short term 132-volts peak
MB: 800 watts per channel
into 8 ohms 93-volts rms short term 132-volts peak
LF: 800 watts per channel
into 8 ohms 93-volts rms short term
132-volts peak Xn loudspeakers may be paralleled with other Xn systems as long as the amplifiers can drive the lower impedances. To main­tain a sufficient damping factor with long cable runs, amplifier loads of four ohms per channel are recommended. The Electro-V oice P3000 amplifiers are ideal for powering the X-Array
systems.
Crossover, Equalization and Signal Delay Controller
The Xn is a three-way active loudspeaker system requiring an active crossover, equal­ization and signal delay controller. For basic applications, the Electro-Voice Dx38 2-in/4-out controller is recommended. For more sophisticated applications, the Klark Teknik DN8000 2-in/5-out controller is recommended. Linkwitz-Riley crossover filters with a minimum slope of 24-dB per octave at 125 Hz and 1,760 Hz are recom­mended, and subsonic filter protection at 50 Hz or higher with a minimum slope of 12-dB/octave is recommended in the low­frequency section. Both the Dx38 and the DN8000 offer appropriate filtering, equal­ization and signal delay capabilities to pro­vide optimum performance of the X-Array loudspeaker systems. Digital parameter settings for both controllers are available upon request.
Electrical Connection and System Wiring
Two semiparalleled Neutrik 8-pin Speakon connectors are used for electrical connection to the Xn loudspeakers with the following
pin assignments:
HF: Pins 4 In / Pins 4 Out MB: Pins 3 / Pins 3 Out
LF: Pins 1 In / Pins 2 Out The Xn wiring diagram is shown in Figure 7. Note that one connector is specifi­cally labeled for input connection only and the other for output connection only. Also note that Pins 1 In are connected to Pins 2 Out, and Pins 2 In are connected to Pins 1 Out. This facilitates wiring of multiple sys­tems with amplifiers. When four Xn systems are jumped from one to another via the input/output connections, the amplifier home run cable will have four HF drivers on Pins 4 (for a 4-ohm load), four MB drivers on Pins 3 (for a 4-ohm load), two LF drivers on Pins 2 (for a 4-ohm load) and two LF driv­ers on Pins 1 (for a 4-ohm load).
Flying the X-Array™ Systems
The X-Array
loudspeaker systems all uti­lize the same rigging hardware and have the same structural strength ratings. Thus, dif­ferent systems may be mixed in an array to achieve the best acoustic results. The rigging system allows for the smallest possible spac­ing between adjacent enclosures, and uti­lizes quick-release rigging fittings for fast installation and tear down. When flown, the X-Array
enclosures are linked together by two removable hinges on the rear of the enclosures at the top and bot­tom. This arrangement enables the enclo­sures to pivot vertically from the rear cor­ners. The relative vertical angles between adjacent enclosures is adjustable and set by two removable rigging straps on the front of the enclosures at the top and bottom. Both the rear rigging hinges and the front rigging straps are installed when enclosures are sit­ting on top of one another. For ease of in­stallation of the hinges and straps, the en­closures self align using feet and cups
mounted on the top and bottom of the en­closures. The relative horizontal angle be­tween adjacent columns of loudspeakers is set by adjustable grids at the top of the array (or by custom-building attachment supports in permanent-installation applications where
®
grids are not used). The removable proprietary rear rigging hinges utilize all-steel construction and are
secured into a proprietary track assembly on the enclosure (similar to the heavy-duty aircraft L-track). The aluminum track is ex­truded as a single-piece track/angle-bracket aluminum assembly and ties into the top, bottom and rear of the enclosure. Metal bars inside the enclosure tie the top and bot­tom track/angle-bracket assemblies to­gether, minimizing the load applied to the wooden enclosure. The rear extrusion will accommodate the New Haven 32102-2 air­craft-type double-stud locking fitting in­stead of the hinge for applications requir­ing a lower strength rating. The removable front strap assemblies uti­lize all-steel standard New Haven 32102-2 aircraft-type double-stud locking fittings and wire rope, and are secured into an­other proprietary track similar to the heavy­duty aircraft L-track. The track is extruded as a single-piece track/angle-bracket as­sembly that ties into the front and side of the enclosure. The track/angle-bracket as­sembly extends from the top to the bottom of the enclosure, eliminating the load ap­plied to the wooden enclosure. A complete line of flying-hardware acces­sories is available for the X-Array
loud­speaker systems including a grid, rigging hinges and rigging straps. The variety of rig­ging hinges and front rigging straps avail­able include those for linking two enclosures together, securing the top enclosure in a col­umn to a grid, and for picking up the top enclosure in a column without a grid. Con­sult the X-Array
Accessories section for a complete listing the available rigging acces­sories. The total weight of a column of X-Array loudspeaker systems that may be supported
by the X-Array
rigging system varies from 454-726 kg (1,000-1,600 lb) depending on the rigging configuration details. An X-Array
Flying Manual is available from Electro-Voice and is included with each X-Array
system shipment. The manual should be consulted for complete structural specifications and detailed instructions for safely suspending and using the X-Array systems.

Figure 4 — Directivity
The directivity index, D tor, R
, of the Xn were measured with a full­spherical measurement system as described in Figure 1.
Figure 5 — Distortion
Distortion for the Xn was measured on axis in the far field in an anechoic environment with an input signal that would result in a sound-pressure level of 115 dB at one meter . The Klark Teknik DN8000 digital electronic unit was used to provide the necessary cross­over filters, equalization and time delay. A frequency spectrum typical of close-miked rock music was employed. The sound pres­sure level was normalized for an equivalent one-meter distance. Plots of second and third harmonic distortion are shown referenced to the fundamental.
