I too have my N805's up on a shelf and back elevated with rubber door stops to fire down at the listening area. Same goes for my HTM2 in the center. My rears are N-SCM's and are up about 12' again firing down at the listening area. Sub is the ASW-825. It certainly suffices although not nearly the most effective set up but it fits the room! All this powered by (the now antiquated) Sunfire Ultimate Receiver and the Marantz DV-8400 Universal. Just now upgrading the TV and DVD to a Samsung 60" and Oppo BDP-93. I'm thinking of trading in the ole Sunfire for a newer Marantz model. Keep tweaking, you'll find happiness...of course I've got a dedicated 2 channel system too to keep me happy on the music listening side :-)
