On the EQ, you mentioned earlier in the thread you were running a Denon AVR, although not which model. Some Denon AVRs (4311 for sure, don't know about others), have an option to bypass Audessey to the left and right spreaker. For stereo sources this would only EQ the SUB, not the mains. I ran this way quite a while with good results. If you happen have the 4311, Audessey XT32 is quite good for subwoofer EQ.
Just something to try, since it may not cost you anything if your AVR has that function.
