I'd recommend getting bookshelf speakers and augmenting them with a sub. You'll get better sound without losing the low end. Plus you'll be able to use the LFE channel right away. Some competative brands are Axiom, Aperion, Ascend, Monitor Audio, PSB, Paradigm, and SVS. You could also check audiogon for used B&W, Usher, Warfedale, Quad, etc. There's plenty of brands that I'm sure I missed. You might want to audition several speakers locally so you can see what type of sound you like. That way we can provide better recommendations for you.
