I think you can have "too much speaker" for a room. In my experience largish floorstanders with a lot of drivers need "room to integrate", meaning sit too close to the speaker and the drivers don't blend together. Plus, too much bass in a small room can be a mess- small rooms will often have many bad modes very near to each other. That can make good bass very hard to get.
I suggest a good two-way tower. Generally a two-way tower will have a bit more cabinet volume than a typical bookshelf and go a bit lower and play a bit louder than a bookshelf, but without "overpowering" a room. Plus, a small room is easier to pressurize in the bass region than a large room, meaning a smaller speaker can play with enough volume and punch to satisfy. Lastly, going with a tower means you don't need stands.
Monitor Audio fanboy that I am, I use a pair of MA Bronze 3 towers in my bedroom. I have a 100 Wpc Techniques receiver driving them, fed by my Denon DCM-380 CD carousel, Pioneer DV-260S DVD player, my old Magnavox VCR, plus my Sony PSOne and Xbox consoles. I have a 32" Toshiba TV for gaming. My rig is almost 100% for gaming- for music in my room I typically listen at my PC (with Griffin PowerWave Tripath amp & JBL HLS-610 speakers), and I don't really watch a lot of TV in my room, maybe just part of a 2nd tier football game that's not worth going downstairs to fire up the projector. At any rate, my Bronze 3's really rock my smallish bedroom (maybe 11' X 12' with 9' ceilings). Good for gaming, but still very nice if I wanna crank up some tunes, too.
