nice setup! how do you like the 2808? I have the 1909 and think it's great, i was so very tempted by the lowering prices of the 2808, but could not swing it monetarily.
I do notice the subs have an option to plug ports, have you tried this in one or both?
from outlaw site--
"Frequency Response:
25Hz. -180Hz. +/- 2 dB w/o Port Plug
18Hz.-180Hz +/-2dB w/ one port plugged "
I also see that they are both behind the couch, is this due to the size of the room? I read on some sites that it's good to keep them adjacently placed in the middle of the walls if you have 2 subs, but the room size might not need all that.
edit: also noticed you plan on redoing cabling, what gauge are you at now?
I'm sure you've read it but:

might help out, personally I'm using 14awg for my front speakers, and even that was a bit hard to terminate (especially into the denon) and I'm not so sure it helps much versus a 16awg for such short distances.
