JBL VTX Series - Ground Stack Limits

VTX A8 | Rigging Manual
Below is an example from LAC of a scenario appropriate to using the VTX A8 SB as the main array frame.
Center of Gravity
Example 4 - CoG with array frame
Center of Gravity
Example 5 - CoG with suspension bar
The venue geometry in Examples 4 and 5 calls for an array design in which the array CoG is perfectly lined up with the rear suspension
point of the top A8 enclosure (Example 4 - CoG with array frame). In this case, the flexibility of the Array Frame and Extension Bar is not
needed and a Suspension Bar can be used instead of an Array Frame (Example 5 - CoG with suspension bar).
