I'm in the process of changing my "A" FOH racks & stacks. The big change will be the changing of the stacks... the amp racks will just get reconfigured. One thing I'm wrestling with concerning the new to me stacks is "stacking them"... as the subs are 33" tall as well as the mid-highs being 33" tall. Ground stacking will put the the centers of the HF hornflairs at approx. 58" (4' 10") off the ground. I'm thinking of building some portable platforms to raise the stacks up approx. 14 - 16"... which will result in uncoupling the subs from the ground. I'm wondering that the caviots might be with that plan?
The options might be:
1) Raise the stacks a minimum of 14 - 16" via platforms: likely preferred from a logistical standpoint, or:
2) Ground stack the subs and raise the mid-highs: less preferred from a logistics standpoint, and would uncouple the subs from the mid-highs, or:
3) Fly the arrays: Least preferred from a logistical standpoint.
