You're sure to get recommendations here, and if you peruse past threads on the forum you'll see a lot of them. You'll also see a lot of advice (that I truly believe) that you really need to listen to speakers yourself to know what is best for you. Try out as many as you can, or at least as many as you have patience for. Why? Here's an example. Paradigm comes highly recommended, but I haven't heard one yet that I like (and believe me, I tried). Other people, however, love them. That's just an example of how personal taste really should drive your decision.
Axiom gets a lot of attention here, so do Paradigm, DefTech, B&W, SVS, Hsu, Onix X-ls (from av123.com), and others. If you go with an internet direct company, look into how much shipping you'll have to pay to send them back. Right now, av123.com has a no-risk trial on their x-ls speakers in which they'll pay shipping both ways if you don't like them. The x-ls might be too big to mount on the wall, though.
Shop around, and have fun.
EDIT - I forgot to mention that I think that MB Quart also makes home speakers.
