again. Note that this change has no affect on the angle of the lower cabinet. Additional Xi-A
enclosures may be hung in succession in this fashion, creating a tall vertical line array (as long as
the working-load limit of all of the mechanical components are not exceeded and a sufficient
safety factor is maintained throughout the array). With the Xi-A loudspeaker systems oriented with
the rigging track on the top and bottom of the cabinets, a short rigging strap is used between the
cabinets to minimize the spacing between the systems. Typically, the LS-3B is used for this task.
If, however, Xi-A enclosures having different dimensions are hung from one another (an Xi-1122A
suspended beneath an Xi-1191AF, for example), a longer strap would be required to
accommodate the different distances In width between the rigging tracks. In this instance, the LS-
1B could be employed. Another option would be to use two RS-1B double-stud swivel-ring fittings
linked with a threaded-chain connector or a carabineer snap hook. (The RS-2B single-stud-ring
fittings could be used in lighter-weight applications.) With the Xi-A loudspeaker systems oriented
with the rigging track on the sides at the cabinets, a longer rigging strap is required between the
cabinets to minimize the spacing between the systems. Typically, the LS-1B is used for this task.
If, however, Xi-A enclosures having different dimensions are hung from one another (an Xi-1122A
suspended beneath an Xi-1191AF, for example), a longer strap would be required to
accommodate the different distances in width between the rigging tracks. In this instance, the LS-
2B could be employed. Another option would be to use two RS-1B double-stud-ring fittings linked
with a wire-rope assembly. (The RS-2B single-stud ring fittings could be used in lighter-weight
applications.)
