I bought the Energy Take 5 system for my living room last winter and love it. GREAT sound for the money.
I wanted wireless, too, but after looking at the options decided to skip it because of what I read about quality, and the fact they'd have wires from somewhere, too, whether to an outlet or a module of some sort. I ended up running the wires behind my baseboards in my living room, although if you're going to put them in the corners of the room, the down-from-the-attic option might work better.
Lots of reviews on
Amazon (but they're cheaper at
Newegg).
