John,

Thanks! Apparently I was completely out of whack. I've played around with x-over and sub settings I so much I forgot to check calibration before starting the test cd.

So now with everybody at 75 dB - sub bouncing between 68 and 77 dB, mains set at small with 80Hz x-over, set to stereo, and pink noise at 75 dB +/- 3 due to sub fluctuations we have a new chart. But John also asked about sub location ...



Sub is about a foot away from back and right wall.

Now for the much improved chart... Blue, previous trace. Pink, calibrated trace.



What a difference! It looks like the sub is still a bit hot. I've only got the gain at 7:30 and calibration is maxed out at -10 dB to achieve ~75 dB. Had to raise the other channels significantly (+4 to +8 dB) to match the 75 dB.

Now it's time to experiment with some "treatments".
