I'll echo what the other guys have said. I have the discontinued M40s and they work very well in my small room (11 x 11). You may have to play around with placement for tower speakers to help tame some of the lower frequencies. M3s may also be an option. I'm running some bookshelf speakers with a similar frequency response to the M3s and am getting a nice bass response. Of course, when you factor in the price of stands (which can be found cheap) you are nearer the price of floorstanders.
