Speaker wire is used to make the electrical connection for your audio system. The speaker wire you use can have a noticeable impact on the sound quality of your system. Even the greatest speakers won't sound their best with poor-quality wire. Our in-wall speaker wire is typically rated CL2-rated for use inside walls, and will deliver the optimal sound experience. These come in white and translucent colored rolls on a plastic spool. They are available in 16awg speaker, 14awg speaker wire, 12awg and 10awg speaker wire. Most come in 250 ft speaker wire rolls or 500ft speaker wire rolls.
