Product Research


Overview: Most speakers do not include speaker wire. You can use this18-gauge speaker wire to connect your new speakers, replace your old speaker wire, or replace the thin speaker wire that was supplied by your Home Theater In A Box or Mini-System. You can get the specific length you need so that there is no unused footage of wire that you need to curl up behind one of your components.
