Im just having a hard time getting my head around them looking the same in a sine wave yet being and sounding different.......just seeking a better understanding.

Music is not a sinewave...
Phase shift is not necessarily T/A. But T/A causes a phase shift. Any change in T/A will shift different frequencies at varying degrees depending on the amount of delay and the length of the wave. Whereas polarity swap inverts the entire signal 180degrees but causes no shift across the time table.

Swapping polarity on the processor changes it before processing (input), but swapping it at the speakers is post-processing (output). There's your sound difference.

So, your saying that the difference in sound is because of the t/a applied?........that's what is avoiding the cancellation I got when swapping the polarity at the speaker? It is a drastic difference between what the processor/ head unit calls phase, and physically changing the polarity. So the sound should remain the same if I swap the polarity at the speaker, and set the phase to normal? As long as my t/a settings are applied?

My shure P4800 does it, as does the BSS soundweb... those are affordable used... MANY processors allow you to build in blocks with drag and drop and line draw patching.
Anybody mind posting a screenshot of these blocks y'all speak of?
Also, this thread needs a much less ambiguous title, I keep skimming over it.
