My prior bass graphs:
|Black Lines are the most recent|
So after Audyssey did it's thing, my listening couch graph(s) look like this:
Not bad, but a significant hole centered at 68Hz and audibly a little bass shy. That's not exactly acceptable to me. SO I did a little fiddling with it to see what I could come up with using the unit's EQ. Check it out:
So the hole moved up a few Hz and filled in a bit. Here's the 1/6octave smoothed (for clarity) overlay:
Oh, I restored the treble back to the speaker's natural response.
The receiver's default setting uses Audyssey's Dynamic Volume. So I took measurements of it's default setting as well:
Some other Audyssey settings with Dynamic Volume engaged:
|The Black lines bypass Audyssey on the left/right channels|
You can see that even though the microphone was in a very close position on all 5 measurements (each one had the microphone position marked), the measurements are significantly different above the modal/transition zone(s). Just more eveidence that there is no ideal "room curve". So calibrating above the transition zone seems futile.
