Ground-Stacked, Upward Firing Arrays
Applications such as covering stadium bleachers from the playing field may be addressed by installing the
VRX932LA-AF array frame to the bottom of the array.
Up to four VRX932LA loudspeakers may be locked together and
ground stacked using the VRX-AF array frame kit, as shown.
[Warning: Do not ground stack more than four VRX932LA
loudspeakers in one array].
When ground stacking VRX932LA
loudspeakers, use The VRX-AF array frame as the base
(as shown) by attaching the loose drop levers, included in the
array frame kit, to the lower rigging bar on the VRX932LA
loudspeaker. When stacking the loudspeakers together, make
sure each loudspeaker is locked together. Be certain that the
surface on which the system is to be stacked is flat, stable and
solid. Up to 4 VRX932LA speakers may be stacked on top of one
or two VRX918S subwoofers. The subwoofers must be locked to
each other using the integral rigging hardware. The VRX932LA
speakers may then be attached to the subwoofers using the same
process described above.

Suspension in Permanent Installations
For permanent installation applications a VRX array may be suspended using M10 eyebolts. Only load-rated,
forged shoulder eyebolts are to be used. A kit consisting of three (3) forged shoulder eyebolts is available from
JBL Professional as part number 229-00009-01. Suspension of the VRX array must employ both top attach-
ment points. The VRX918S subwoofers must always be at the top of the array.
Eyebolt Suspension
The following table defines the maximum number of speakers that may be suspended using the two M10 eye-
bolt attachment points provided on the cabinets. A minimum design factor of 7:1 is maintained for all speaker
configurations at or below those indicated in the table.
