If you end up with smaller speakers, please consider some good stands. My Paradigmn Titans-a nice option for you by the way-are mounted on Sanus stands filled with kitty litter. Between the speaker bottoms and the stands are strips of tacking compound-Ace Hardware's version of Blu-Tak. They sounded much better! The rigidity of the stands and vibration damping of the tack gave my speakers much better focus and clarity. More detail. On the other hand,by the time you buy the spaeks and stands, you approach the price of comparable towers. The choice is yours. BTW-in addition to Paradigmns, listen to the PSB Alpha series. I bought a pair for my brother in law. Stand mounted, they sound great in his den.
Good listening!
