The resulting response is something arbitrary. It is no longer tied to the Audyssey curve in the lower frequency regions. Maybe we should just tune the low end by ear.

I don't understand that statement but allow me to provide some info that may clarify things for you. Audyssey attempts to provide as flat a FR as possible. The actual resultant curve depends on many variables. Prominant amongst those are the severity of acoustic problems of your room, speaker/sub capability, speaker/sub placement and Audyssey's finite DSP limitations.
In tweaking your system you should not lower the xover from what your processor determined, as Audyssey does not filter below the -3dB point. But you can chose any higher xover that you prefer. If speakers are set to large, those choices begin with 40Hz. You can listen and measure 40, 60, 80 and see if there's much difference and what you prefer. In all cases Audyssey is working as it should. With XT the SOP was to raise all xovers to 80. But with XT 32, there's no inherent reason irt Auydyssey itself to chose one xover over another. Any SQ difference between them is due to the room/gear factors I referred to earlier.
