I actually used the pink noise test on the Digital Video Essentials Blu Ray thru the Panasonic's 7.1 analog outs to calibrate that input. Then I used the internal test tone on the 659 to calibrate the other inputs. (The 659 allows different channel level setting for the multi channel input)

When I used the internal YPAO auto calibration, the speaker levels were OK, but it would set some speakers to large & some to small and the distances were off. Had to turn the EP500 down to virtually no volume before it could complete the calibration. So, I didn't place a ton of faith in it.

I did turn the sub a few inches and set the trim to Half/Full and it seems to even the bass out a little. Right now the low end (30-40Hz) is still off the charts & really dominates the room. But the 50-80Hz range is lacking.

Certainly going to try the oppostite corner as soon as I can get some help moving the TV over a few inches! Maybe that will help even the bass out.

Truly appreciate all the tips!
