Okay, that was sort of interesting.
I first checked bass again out of curiosity. This time I really couldn't tell much difference ... I think the radiator is radiating regardless of polarity.
But I did the above test, and also found a different one on youtube, and they showed the same thing:
If using the 'correct' polarity by manufacturer standards --
In phase plays more towards the left driver, out of phase from the mid-range driver.
If using the 'incorrect' polarity by manufacturer standards, (yet correct by audyssey) --
In phase plays more towards the mid-range driver, out of phase from the left.
And if anyone is confused, it's a 3-way, so that's why there is a middle driver. Left woofer, mid-range smaller woofer, and right full-size radiator.
I didn't really check which I preferred best with actual audio (getting late, sleepy, so didn't feel like going crazy with it).
Although I'm curious which is supposedly correct?
