Glad somebody finally asked the question. IMO phase shift at bass frequencies is a benign as bass distortion ... it takes a lot of it to be heard.
Anyone who has played with Subs will know just how much the phase angle can be varied with little ill effect other than to change the response at different frequencies depending on room resonance and speaker placement.

my experience is the opposite, I've found dialing in the phase of a sub especially critical to the soundstage.
This wasn't my point. Sorry, should have better explained.
In the context of rolling off at say 2-3 Hz vs 10-20 Hz the phase angle change is only 20 degrees or so at say 50 Hz and less as frequency in increased.
One would need to vary Sub phase by 90 degrees or so to be audible and this assumes a good sub with steep rolloff that doesn't leak into mid bass and mids too much.
