I agree with you on the center Jack. The pink noise test with meter, or the receiver built in setup mic, always puts my center about 2dB's below the mains. Heck, you can't even hear the voices in movies at that level. I always bump up the center 2-3 dB's above my 60's. I wonder if it has anything to do with being a 6ohm design versus and 8ohm, like my 60's.

I'll have to keep playing with the sub before I deside if there is an issue. I still think it may have something to do with being on concrete versus on pad/carpet.
