So I've been playing around with my subwoofer phase and distance setting, trying to find the correct/optimal/best setting. You can see my previous thread with more details at this link, http://www.avsforum.com/t/1464406/setting-subwoofer-phase-properly-with-omnimic
Looking at the image below, all traces are sub plus left speaker with 80hz crossover
black = with Audyssey set distance, so no tweaks from Audyssey
blue = same as black but increased sub level 3db
orange = added 3.5ft to sub distance and adjusted phase from 0 to 180deg (same sub level as black trace, so -3db from blue)
What bugs me is they sound much different (comparing orange to blue as black obviously has less bass). So I'm wondering how I choose the "correct" setting. The blue trace is more what I have been listening to previously and the bass seems to hit hard and be timed properly, at least according to my ears. The orange trace seems best from the charts, saves me 3db subwoofer headroom and makes the subs really disappear but hard to tell if that is how it should be or if it is smearing things.
Which would you choose and why?
One more piece of information, with the Audyssey set distance (blue and black traces) the time alignment seems correct with the center channel as well based on plots. If I go with the orange trace settings but center channel is out of phase with the sub and I get a nasty dip of -15db at 80hz.
Looking at the charts I would think orange and blue would sound nearly identical for music (which is what I have been listening to for comparison), but they don't. This almost appears to be one of those things where even though the measure the same the sound different (though I'm not usually in that camp). So looking for input and feedback from others.
