Which amp are you using, and what kind of music do you listen to? How large is your room? That would be useful information to recommend any speaker to you.
Generally, I'd echo the NHT3.3 recommendation, but they do need power in spades to make them sing, and will require quite a bit of space. I would not use them in a smaller room as they'd likely overload the room with bass. In turn, setup correctly in a large space, and with the right amount of current, they will put out some of the deepest, tightest, well-integrated bass I've heard come from a pair of speakers.
