A surround sound theatre package is going to be best used for watching movies
or things that require a all around sound. Just for music you should only need
two front speakers and a sub woofer.
With surround sound and a high quality digital reciever
you will expierence the magic as if you were there.
How it works is that the reciever seperates the sound out to the speakers. Its going to give most of the voice sounds to the center speaker and the back ground and surround sounds that make you feel like your in the middle of the action go to the rest of the speakers. And the subwoofer adds all the base!
