I don't think the 805s would *require* a subwoofer in a 12' x 14' room. However, it depends on what you like. If you do choose to try a subwoofer (ideally a pair - yes, I know it sounds overkill) make sure that you can roll it off at 30 Hz or less.
If you can drop the coin, go for a REL (or 2). For less money, I like (and own) a pair of Martin Logan Dynamos and roll them off around 35 Hz. I have a smaller room than you, too.
Also, check out "the Swarm" by AudioKenesis. I have not heard it, but in theory could be killer. Duke is a great guy, too.
