Another thing to consider is that you could run the system in multichannel stereo to spread out the sound when looking for background music every where in the room, opposed to blaring it out with just the 2 floorstanders. The volume doesn't have to be as high when the music is coming from all the speakers in the room. I do this quite often. And YES for a dual sub system in a room of that size.
