What's wrong with this picture?

Never seen horns painted that colour.

Good guess!

Actually the horns are rotated 90 degrees from proper positions. They appe ar to be an artist's conception of the Electro-Voice "Compound Diffraction Projector" (or "Crappy Damn Projector" as we used to call it when I was in college). For maximum horizontal dispersion the horn must be vertical. h ttp://tinyurl.com/EV-Compound-D-P

The message went over everyone's head.

Well if you want the graphic artists to draw technically correct pictures (ie not the public's conception) good luck !!

Two of the speakers are defective, they are not printing graphics in the air.
