I have two subwoofers, both connected to a single output on my Denon AVR. When I use Audyssey it obviously provides me with one distance (that doesn't match the distance to either of the subs from the sweet spot). Should this distance be altered? Doesn't this impact when the subwoofer signal reaches my seat vs the other speakers?

I'm also getting conflicting advice on-line about whether set subs to LFE or LFE+Main in a 5.2.2 home theater system. Your thoughts?
