Absolute Phasing

"...Does it matter?..."

i most cases no but the Infinity Sub controller for example will pop if connected out of absolute phase. I know, I have two dead boxes right now. 

It matters if you have sub woofers attached to the same Pre Amp.
The main speakers could be potentially out of phase with the Subs.

Nope. Next spurious pseudo-reason?

try it both ways... go with the one with better bass response

This involves listening. People start doing that, next thing you know they're talking about what they're actually hearing. This is an audiophile site. Let's keep it theoretical, okay?

My man millercarbon! You have a way with words. Sarcastic, blunt but to the point. 👍 Thank you all for your responses. 

It doesn’t matter because the sub’s driver is not on the same plane as the main speakers, therefore, the phase alignment is already off due to physical placement. This is one of the reasons that a lot of higher quality subs have the ability to adjust phase.
