Calibration madness

Finally got my Avia disc in the mail the other day, so I could try to do some kind of audio calibration with the sub. I'll try not to go into the long version, but the short version has two points:
- there's definite "weirdness" going on between my sub + right front, and sub + left rear speakers. SPL from sub + RF is probably 5dB below sub + LF, for example.
- there are weird tone issues between my fronts and center channel. Granted they're not the same speaker series, but they're at least the same brand, I thought thinks would be close, but a white noise (or is it pink? I don't know) that pans left to right is supposed to sound the same as it goes across the front of the room, and it takes a definite dip in my system when it gets to the center.

Yes, that's the short version. The long version involves complaints about not having a real crossover on my receiver, peaks/valleys in frequency response charts, variance in sub level with test tones of different sources, and limited sub placement options in the room. :-P
