I have a room that is almost the exact same size as yours and have just recently bought a pair of GMA Callisto speakers that are working out great. They are easy to drive and are very musical and non fatiguing to listen to. I would highly recommend that you check them out. There are a few in the for sale section that I feel are great bargains.
I'm not sure what type of music you prefer but there has not been any genre that I have thrown at my new speakers that didn't sound awesome! Rock, Electronic, and Reggae (which is rarely recorded in audiophile quality). My Jazz, and world music albums sound terrific too!
The Callistos offer a great balance of warmth and detail that really make my toes tap and puts a smile on my face. For me that's what speakers should do.
Good luck on your hunt!
