I agree with Tubeking that conduit is the way to go.
It allows you an opportunity to change wires should you ever decide to change speakers, and the wires that work well now, don't with your future speakers.
My two cents worth.
PS I'd go with 2 inch conduit if you can. That allows you to use most cables, no matter what the thickness or stiffness.
í-AAGood Luck!
