That response from MC was absolute nonsense. For someone who perpetually lectures on the need to simply listen and let ones ears be the judge on whether a difference in sound can be heard from making changes, I find it incredibly ironic that he would claim phase adjustment does nothing in any setup. Sorry MC but you’re wrong. Perhaps in a DBA setup like his the phase adjustment provides a negligible benefit. That point I won’t dispute because I’ve never personally utilized a DBA in my own room. However, when using a single sub the phase adjustment absolutely does make an audible difference at the listening position. I have a JL E110 with continuously variable phase control and it’s a helpful tool for getting the sub to perform at its best. One just needs to shut their mouth and listen to hear the truth.
Critical subwoofer tip
I assume that everyone already knows the importance of phase matching a sub to the main speakers but it’s a little more complicated than simple 90 degrees or 180. The B&W sub that I have has four choices. In every case there has been a definite correct position that can be non standard. My current setup shined at 270 degrees vs the std positions. It’s completely obvious and the other choices would not have been satisfying.
From my lengthy experience I would want a subwoofer with several phase choices. I personally don’t see how one could seamlessly integrate the mains and the sub without this flexibility. No one asked but i thought this info might be useful to anyone purchasing a subwoofer. YMMV
