In a small room you will probably have enough power for most of the time. I think the bigger problem is the smaller room. These speakers sound their best when you get at least 10 feet away, 12-15 feet is better, and they like to be far away from the walls as well. My room is 13 x 20 and just big enough for me.
They are excellent speakers and will sound better and better as you improve your system.
