Nice second try! Fry a pair of 802 Diamonds?
I think the Audyssey low frequency curve looks pretty good, with the exception of the null at ~66Hz. This could be improved by either adjusting the sub placement, or by adjusting the sub distances in the AVR menu. The second approach is called the "sub distance tweak", and varies the phase differences between the subs and the mains, which can improve the smoothness of the frequency response in the vicinity of the crossover. I would try this before adjusting the sub placements.
If you need to move the subs around, remember that a very small distance can produce significant frequency response differences. For example, when I am experimenting with sub placements, I place s strip of masking tape on the floor and mark intervals of 3" on the tape. I then move the sub 3", measure, then another 3", measure a second time, etc. Repeat in the other direction. One direction or the other may result in a shrinking of the 66Hz dip, and hopefully not introduce a peak or dip elsewhere. It's largely an iterative, trial-and-error process.
The full-spectrum response looks really quite good. Congratulations!
1. Try to improve the 66Hz dip with the suggestions above.
2. Generate Waterfall graphs to assess modal decay times (consult the Guide).
3. Generate Impulse graphs (ETC) to assess room reflections in the spectral frequency range (consult the Guide).
4. Post results!
