Hi,

Get good-quality 14-gauge copper cable from Radio Shack, Home Depot, Parts Express, etc. Use the same cable for all your speakers, but they do not have to be the same length. There is no advantage whatsoever to expensive exotic cables. If you pay a lot, you may think they sound better but they do not. Other visitors to the site may have other sources as well for good-quality inexpensive cable.
