I had a good interview yesterday for a part time live engineer position at a local wine bar. I noticed right away that his HF cabinet horns were about mounted straight up and down, eight feet off the ground, and within a foot of the standard drywall ceiling. They're on top of a sub, and two 12" (maybe 15") mids. They are almost certainly JBL G730s on top.
The vertical dispersion angle of these speakers are 40
