None of the above,
With the Z-680s all your friends in the neighborhood would be able to enjoy the music or DVD at the same time you are, should you choose.
Seriously, they do sound amazing and you do not have to crank them 100% all the time. (Only for block parties.)
Take Care,

P.S. You just want good 5.1 Surround Speakers in order to get the full use out of your new system.
