Tostado,
IME, the problem with set-up by ear is that you're trying to optimize for 3 major variables at once (and a few minor ones, too). Smoothest response will vary with room position, as will the native output level from the sub (as reinforcing or destructive room interactions have their way with the low hz output). The placement with the smoothest response will likely require a different level setting on your sub than the placement with the second smoothest response. Finally, the x-over frequency (and slope, if applicable to your set-up) must be optimized for the particular placement you've chosen. As above, likely to differ (unpredictably) between best, next best, etc. And you've got to pick the best compromise....
I'm sure you're better equipped for the task than I am, but it's an awful lot to ask of anyone to optimize that equation by ear.
Good Luck (and kudos on the self-improvement project, too).
