    Last night, after reading many posts recommending to set all speakers to small, I was recalibrating my system with AVIA. When I came to the frequency sweep tests, response was flat within 2dB for most of the first part, with higher frequencies.

    My crossover is set at 90Hz and while this is still not definitive (none of the settings are...), response was still ok there.

    When the tone came to 60 Hz, though, ehte needle on the SPL meter went like almost 10 dB above the reference I was using.

    My question is if this has anything to do with the AC or if it's just a coincidence that for my room resonance happend right there.

    Dennis: lots of folks have bumps in the 50-65Hz areas, including me. Mine is room induced and I had to use an EQ to tame that peak a bit. You might try moving your subwoofer around a bit to see if that peak can be reduced, otherwise, it might be EQ time if you can't live with the 60Hz bump.
