Stereomaniac I don't think your room is that small especially if you place the speakers firing into the 30 feet. As audiojerry stated it's not just how far you listen. If you were six feet away from your speakers sitting a foot away from the back wall you'd encounter alot of reflection of sound that you wouldn't encounter if the walls were 24 feet away.
However, if you are placing your speakers so that they fire into the 12 foot part then your speaker choices would be different.
Anyway, if you were to place your speakers so they fire into the 30 feet of your room, I would consider a floor standing speaker. That will alleviate a lot of your subwoofer concerns. Here are some contenders: Dynaudio Contour 1.8, Proac Response 1.5's, and B&W 804's. If I were in your shoes these would be what I would listen to. The Dyaudio's may need more power than you have.
IF you decide to go the monitor route, try the smaller speakers of the above ones I mentioned in the same line.
I'm sure others can offer their advice as well. Good luck
