Hey Earl, thanks for the info! Yes, that 1K bump does help the articulation.

Below is an idea of coverage. The shaded area is 70 degs, the patten given for the 803 horn. If I'm reading the map scale right, the distance to the abck of the stands is ~250 feet, not 130 as I posted earlier. Or about 1/2 the distance we tested yesterday.

I really doubt one horn can do it, but 2 or 3 should be OK. Maybe run the center horn at 16 ohms and the outside horns at 8 ohms to shade the power a bit.

Any advice from the old pros is welcome.
