Interesting to follow your progress. I still need to do fine tuning of sub integration myself. I'm approaching mine using the receiver distance setting for the phase adjustment while keeping the knob on my F8 sub at 0 degrees. If I had your results, I'd expect to go with 0 degrees delay (or try other intermediate values) and reduce the sub level 3-5 db. Then expect Audyessy to handle the 150-200 irregularities. Ideally, you'd include the response a bit below the crossover point as well, say from 60 Hz. I'm looking forward to others' comments.
