I have my "process" that I go through, and by now I've done it enough times that I'm comfortable. Also, my speakers are placed with a tape measure and I've put small dots to mark their spots in case somebody bumps them (same with my couch and where I place the mic boom).
- With the app I do my careful calibration, all 8 positions, clustered within 12" to 15" of the main MLP.
- Re-assign my speakers to "small" and raise to 80hz crossover.
- Verify with REW and umik-1, but have to add about +2dB to the SW trim just to play it level with the speakers...not including my own boosts. What Theo said seems to be correct, not sure why Audyssey overestimates it but I think it's because they assume you will be using DEQ and they likely also want to not overboost.
- I disable MRC, and use the Target 2 rolloff for Reference.
- I typically use DEQ for movies; I've measured it and listen at lower volumes and like what it does. I have bass capable towers all around and a beefy center so the bass doesn't sound muddy like others complain about. I do reduce the surround trims by -3 since I usually listen at -15 and don't want DEQ to raise the surrounds trim (another common complaint about DEQ).
- I also have my similar settings without DEQ when I listen to music in which I found my optimal tone control settings. I also limit EQ correction to 300hz for this.
