I've got the Mirage MX 5.1 speakers. They are small, black, slick looking, and totally adorable. They also have a 360 tweeter so it doesn't have to be pointing directly at your ear to get the effect. 800watt mini-sub. Small but packs a good punch and the sub is adjustable so I don't blow out the neighbors since I live in an apartment. Powered by a mid-level Pioneer receiver 7.1 system in case I want to expand the speakers some day.
I've got the 52-inch Samsung TV. That's what's in your photo, yes? 52 or 56?
edit: by the way, if you are worried about your speaker sound consider the wire as well. I've found that getting the right size wire has made a big difference in the clarity of the sound.
