I don't think your message got an answer -- here is mine.
1. I measure speaker distances first and enter them into my (STR) preamp.
2. Then I do corrections. The STR preamp holds 4 profiles, which I use for slightly different room gain settings and such.
3. Using a 3d-party software, I set the sub phase for each channel, running the signal through profile #2 on the Anthem. I chose #2 because at present the auto-phase module doesn't affect that.
4. Because, as you said, filters affect phase, one might iterate through steps #2
until there is no improvement. I didn't do that, but I did run the ARC phase-adjustment module, to make sure profile #1 is free of past phase settings.
5. Based on measurements of my setup, differences among profiles are not large enough to make phase settings
profile-specific. So I just leave the sub phase alone from then on unless I make major changes in the correction. The correctness of this setting can be verified by running the ARC phase-adjustment module again (if your gear supports that) and seeing if there is a change, or by measuring to see if big swings in FR near the xover frequency occur.
I hope that's helpful.
