In Reply to: The $64,000 guestion, how do you determine how much tilt you have?? posted by Robert Hamel on May 15, 2003 at 08:25:24:

You're right that it's a matter of geometery. You can calculate the source locations, but you have to know the crossover phase, acoustic phase and physical position of each driver. You can also measure each driver with a click test and see the delay between them. That will tell you exactly what the source location is. Knowing the positions, you can determine the centerline and the arc of the off-axis-nulls.
