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..
