I have just bought the a WD TV live box and I am woundering how I would setup a surround sound system with this. I have no experiance with surround sound systems so I have no idea what I need? Do I just need a 5.1 speak system or do I need a mixer or somthing aswel? I was looking at something cheap like this: http://www.ebuyer.com/242265-logitech-z506-5-1-surround-sound-speakers-75w-rms-980-000432
Would this work do I need to buy anything else or would this work fine on its own?
