Given the size of your room, I'd recommend the 805S with a pair of REL Quake or R205 subs (yes, I said "pair" for a 12' x 14' room). While I like my Green Mountain Audio speakers better, I have owned the N805 (along with a REL Strata III) and did enjoy the combination.
Stick with the 800 series within the B&W offerings, and I'd look at the "S" or "D" speakers within the 800 family. I'd also think you'd be better off with the 805S + subs than the 804D.
...and save some money for room treatments.
