Todd, you are on the right track. There will be a 'BEST' configuration with a speaker (especially horns) and a SET combination. This combination should NOT be changed.
Think it through: The speaker (horn especially) has lots of 2'nd harmonic. The amp, being SET , etc has lots of 2'nd harmonic. If you get them out of phase (the 2'nd harmonic), then they should cancel. What a deal! Free distortion cancellation.
Is this practical? Sometimes.
Absolute polarity, like what Clark is referring to, is a different problem entirely.
