The best way to ensure the widest possible stereo listening area is to aim your left and right F81 systems,
both horizontally and vertically, so that their on-axis lines cross over at ear height at approximately 2/3
the distance to the rear of the audience.

2/3rds rule for audio-visual applications
If your loudspeaker system is providing front left and right sound for a specific video screen, place your
loudspeakers so that their high frequency units are approximately 2/3rds up the screen and then tilt them
so that they aim approximately 2/3rds across the audience area.
The above aiming rules still apply, of course.
