There are a number of good options to choose from, depending on your personal preferences and budget. The Your System Saloon includes a number of posts listing equipment used by other Outlaws and discussions of some different speaker brands. If you have a particular budget in mind, that might help folks offer suggestions. In the meanwhile, some of the usual suspects would be Paradigm (I use some older Paradigm Reference), Boston Acoustics, Klipsch, Magnepan (although I'm not sure how well they'll work in a small room - some Magnepan owners can comment better on that), Polk (although the larger and more expensive Polks are very inefficient speakers that often need a lot of power), Definitive Technology, B&W, Axiom, Onix Rocket, Aperion, Energy, and probably half a dozen that I forgot. An idea of budget could help thin the list a bit.
