Yeah, you'll only notice phase changes in the sub in relation to the mains. It becomes apparant around the crossover area when you play both the sub and mains.

To elaborate a little, an octave or so above and below the crossover point, if there are phase-related response issues. My experience has been that response will look real ragged there, with sharp peaks and depressions.

In your situation, the response problems you’re having are far too broad, and/or pretty well too low to be phase-related.
