These are what I use. Cambridge SoundWorks The Soundworks II Speaker System for Computer, PC, Mac, iPod, iPhone : Promotions
The stands and volume control are removable and there are mounts on the back, I have them mounted to the wall with a simple screw and use paintable wire covers to hide the wires. They give a nice full sound and reproduce voices very well, which can be a problem with some speaker systems that aren't intended for TV. Music sounds good as well
The amplifier is in the subwoofer, so no receiver required.
My receiver quit working about the same time that I bought this house and I decided that I didn't want the bother or the expense of a new receiver and taking the time to run, as well as hide a bunch of surround speaker wires. This gives a nice, full sound and is nice for music, it works well for now.
