What I did first was run the auto—cal on my onkyo , which set the xovers at 40hz for the fronts and rears ( which I wouldn’t use since that’s below the rated range of these speakers ), so I manually changed them to 80hz. Afterwards I did some listening with music, and found that the bass didn’t sound right ( unbalanced from upper to lower bass ). So I checked all the trim levels, and they checked out...so thats when I decided to mess with the xover settings again. After some time selecting other xover points while music listening, I found that using the 50hz xover for my fronts and rears yielded the best results. I did find that a 100hz xover sort of worked, but it created more nulls and peaks, hence why I went with the 50hz.
Like stated before, I know this doesn’t coincide with what is discussed here or in that article, but in my particular situation these settings work...I don’t listen at loud levels ( I live in a an apartment ), I stayed within the speakers rated frequency range and I’m pretty sure placement and living space’s acoustics are playing a role in this as well. So, to answer your Q lovinthehd, it was an auto-cal measurement first, then an ears only cal afterwards. I don’t have the REW, measuring mic or laptop at my disposal, but its easy to hear any bass irregularities in my apartment...IMO
