X-Array™ enclosure shell and the standard X-Array™ flying hardware. Xn: Near-field, three-way, LF/MB/HF loud- speaker system with a rotatable 60° x 40° cover- age pattern. The system has one EVX-180B 457-mm (18-in.) woofer, one ND12A 305-mm (12-in.) MB driver and one ND5-16 76-mm (3-in.) HF compression driver. -
Page 6: Loudspeaker Enclosure Details
X-Array™ Loudspeaker Systems primary support for the loudspeaker enclosures, while the front rigging hardware is mainly for aim- ing the enclosures vertically. (The front does pro- vide some secondary support, however.) Figure 1a illustrates an array column suspended with a grid. Like the loudspeaker systems, the grid utilizes horizontal rigging-track hardware at the back and vertical rigging-track hardware at the front. - Page 7 WEIGHT: 87.1 kg (192 lb) WEIGHT: 87.1 kg (192 lb) WEIGHT: 83.5 kg (184 lb)

X-Array™ Loudspeaker Systems dishes) are located on the top. When one enclo- sure is stacked or lowered on top of another, the male feet on the bottom of the upper enclosure slide into the female feet on the top of the lower enclosure, automatically aligning the enclosures. - Page 10 X-Array™ Loudspeaker Systems will come out of the track once it is aligned with the center cutout. For added safety, the locking pin has a special shape which engages with the track to prevent it from vibrating out of the track hole during use.

Page 11: Rigging Strap Details
X-Array™ Loudspeaker Systems as shown in Figure 5c. (Note: If one pickup hinge is installed incorrectly with the chain at the center of the track, the second pickup hinge will not fit into the track cutout.) Key dimensions for the Xrhp rigging hinges and the enclosure are presented in Figures 4c and 5c. -
Page 12: Grid Details
X-Array™ Loudspeaker Systems be used on custom wire-rope assemblies to attach to the rigging track on the back of an X-Array™ enclosure as shown in Figure 7b. Key dimensions for the rigging straps on the enclo- sures are presented in Figure 7b. In light lifting applications, double-stud-fitting custom assem- blies could be used instead of the Xrhp pickup hinges. -

X-ARRAY™ FLYING TECHNIQUES The X-Array™ rear-hinge/front-strap flying system makes constructing vertical arrays easy, predict- able and repeatable. The enclosures utilize rig- ging hinges that allow them to pivot at their rear corners. -

Page 15: Using The Xrss (Short Wire-Rope Rigging Strap) Between Enclosures
X-Array™ Loudspeaker Systems Angle = - (Holes Showing) x 1.8° for the Xrsl where negative (“-”) angles indicate down- ward angles and positive (“+”) angles indicate upward angles. For example, when the fittings of the Xrsl straps are inserted into cutout #0 on the grid and cutout #0 on the top enclosure (position “0-0”), as shown in Figure 10b, no holes are showing and the angle of the top enclosure relative to the grid is... -
Page 16: Multiple Enclosure Angles
X-Array™ Loudspeaker Systems angles between enclosures also applies to the Xrss when determining angles between the top enclosure and the ATM grid: Angle = 7.2°- (Holes Showing) x 1.8° for the Xrss where negative (“-”) angles indicate down- ward angles and positive (“+”) angles indicate upward angles. -
Page 17: Balancing And Distributing The Load
X-Array™ Loudspeaker Systems easily set by coupling the grids together. The ATM grid and couplers are shown in Figures 8e and 8f. The splay angle between array columns is determined by the position of the couplers within the grids front and rear bars, which is illustrated in Figure 8g. -
Page 18: Balancing The Grid
X-Array™ Loudspeaker Systems detailed discussion of the structural strength of the rigging hardware. Balancing the Grid: When using a grid, as shown in Figure 14, the pickup point on the grid (the hanger) must be positioned directly above the combined center of gravity for the entire col- umn of enclosures so that the grid will be bal- anced and hang level. -
Page 19: Cautions For Pull-Up Lines
X-Array™ Loudspeaker Systems This configuration cannot be implemented with a grid like that shown in Figure 8 because the grid cannot be balanced. To attach a pull-up line to the bottom enclosure in an array column, a long Xrsl rigging strap (or other similar strap) may be attached to the two round cutouts in the rear rigging track as shown in Figure 18. -
Page 20: Cautions For Working-Load Limits And Safety Factors
X-Array™ Loudspeaker Systems loudspeaker systems are based on test results in which parts were stressed to failure. Manu- facturers typically present the structural-strength ratings of mechanical components or systems as either the working-load limit (WLL) or the ulti- mate-break strength. Electro-Voice chooses to present the structural-load ratings of the X-Array™... -
Page 21: Simplified Structural-Rating Guidelines
X-Array™ Loudspeaker Systems immediately determine on site whether or not an array is safe without having to make weight-distri- bution calculations. The structural strength ratings of the individual rigging points and the overall X-Array™ enclosures are also presented below so that a complex structural analysis can be made for any array configuration. - Page 22 X-Array™ Loudspeaker Systems page 18...

X-Array™ Loudspeaker Systems pull. The Xrss short wire-rope rigging strap, Xrsl long wire-rope rigging strap and New Haven NH32102-2 fitting have identical structural- strength ratings as shown in Figure 21. The ratings vary with both the side-to-side and front- to-back angles and, therefore, are illustrated with two graphs. - Page 26 X-Array™ Loudspeaker Systems page 22...
