Great stuff posted!
I used the 4550 bins, 4560s, double scoops, and JBL 2441 drivers on 60 and 90 degree horns into the 80s! I can't even imagine, carrying those around now.
Looking thru the notes, I used a lot of that old stuff. Those super long throw JBL horns sat in our warehouse waiting for an outdoor show that never came.
