quickly, and offers such flexibility in the vertical angling of cabinets that pull-up points are usually unnecessary. Furthermore, all of the flying Xi loudspeaker models in- clude the same rigging hardware, allowing different models to be mixed as necessary throughout an array.
The working-load limit (for an 8:1 safety fac- tor) for each rigging point on the Xi loud- speaker enclosure is 227 kg (500 lb) for a 0° pull angle and 170 kg (375 lb) for a 90° pull angle when used with the New Haven NH32101-2 double-stud fitting, and 113 kg (250 lb) when used with the New Haven NH8192-2S or Ancra 42546-10 single-stud fittings with locking pins. The working-load limit(for an 8:1 safety factor) for the overall enclosure is 340 kg (750 lb). (Consult the X-Array Install™ Flying Manual for specific structural ratings and limitations.) The en- closures may be oriented with the rigging track on the side of the enclosure, or on the top and bottom, and may be daisy - chained together as long as the safety fac- tor is 8:1 or greater and local regulations are met. For fire safety and additional structural strength in both flying orientations, top-to- bottom and side-to-side metal straps link the rigging track inside the enclosure.
CAUTION: The Xi loudspeaker system should be suspended overhead only in ac- cordance with the procedures and limita- tions specified in the X-Array Install™ Fly- ing Manual and manual update notices.
Field Replacement
Normal service for the Xi-2181 requires only
a#2 Phillips screwdriver and a 3/16-inch hex-key wrench. The drivers may be ac- cessed as follows:
LF: First remove the grille, then remove the screws securing the hatch on the front of the enclosure. Remove the screws securing the 18-inch woofer and lift the woofer out of the enclosure. In the event of failure, the entire woofer must be replaced or reconed.. The following service parts are available from the service department in Buchanan, Michigan USA:
LF #818-2883 EVX-180B complete driver. The complete drivers are available only for repair replacement and are not available for general sale.
