This is the back of the Z906 sub. I want to buy these speakers tomorrow as they have a crazy deal. Only 290$! Basically the only logitech speakers I've had experience with is the x230's and z623's which both use a single 3.5mm input to provide the sound for the 2.1 setup. I want to use these speakers for my HTPC in the guestroom upstairs that is never used and the the only available system I have has an Asus P5QL-SE motherboard. Would this suffice for the connections needed to run these speakers. Sorry I'm not very "audio smart".
