Final Notes:

Both the horizontal and vertical coverage angles roughly match Faital's spec, both exhibit general tapering or narrowing in the pattern as frequencies rise so it's difficult to put an exact number on what the nominal coverage angle should be. Otherwise the response remains very linear compared to on axis except the kink in the top octave due to mismatch between the driver exit angle and horn throat angle.

I suspect the exit angle/throat matchup is closer on this CDX14-3060 so the kink in the off axis response in the top octave does not as severe as the other two drivers tested.
