Too bass dominent? If you go smaller "sealed" speakers, with limited bass extension, this won't be an issue with "boom". M&K's excellent K7 and K4 satalites are superb for music/movies, very dynamic, focused, and musical/clear, and superbly engineered. They play down to 80hz nicely (so play as "small" anyway), and mate with a well placed sub. Can't loose if you take care with setup here.
Other smaller considerations are smaller Super Zero's, Infinity TSS750's, Polk 7000 series(?), etc. These will require you cross over higher possibly. But the M&K's are solid down to 80.
