Here's why I ask. I'm getting rid of my wireless speakers that I use for my PC's surround. (I just love how I'm nowhere near line-of-sight between the transmitter and speakers, which are only about 4' away from each other, but just moving creates static!) I'm going to run wires through the floor (I love open-ceiling basements!) to connect to the speakers that originally came with my 4.1 system. I have higher-quality speaker cable, but this is for basic usage and the occasional DVD watching. I use my REAL home theater system for serious DVD watching. Since CAT-5 is four-pair, I was thinking of using two pairs per speaker (2 wires for positive, 2 wires for negative, times two speakers per cable) and running one CAT-5 cable instead of two, much-thicker speaker cables. We're only talking about a distance of roughly 8' MAX. Has anyone tried this? Good results? Bad results? Keep in mind that I'm not an audiophile, so I'm looking more for "will this work and still sound good?"
