12AWG oxygen-free copper speaker wire

This 12AWG speaker wire uses 99.95 percent pure oxygen-free bare copper conductors for lower resistance than copper-clad alternatives. It suits installers and audio enthusiasts running long in-wall or whole-home speaker cables. The CL2-rated white jacket meets residential in-wall safety requirements. Supplied as a continuous 500-foot spool for flexible cut-to-length installation.

CL2 rating limits in-wall use to residential spaces

The CL2-rated jacket is approved for installation inside walls of residential-class buildings only. It does not satisfy plenum or riser fire codes required in commercial structures. The two-conductor design carries a single stereo pair or one mono channel per run. Oxygen-free copper reduces added resistance that can alter speaker impedance over distance.

Check local code and run length before ordering

Verify that your project only requires residential CL2 compliance and not a higher fire rating. Measure each cable run to confirm the 500-foot spool provides enough length for all speakers. Ensure your terminals accept 12AWG bare wire without adapters. Confirm you need a two-conductor layout rather than four-conductor for bi-wire or multi-zone setups.

Questions about this item

Should I choose the 12AWG 500ft spool or a different gauge for my run?

The 12AWG gauge on this 500ft spool suits longer runs and higher power; thinner gauges add more resistance over distance.

How does the 99.95 percent pure oxygen-free copper affect sound in my system?

It keeps added resistance far below the 68 percent conductivity of copper-clad aluminium, preserving speaker impedance and detail.

What does the CL2 rating on the white jacket allow for installation?

CL2 means the jacket meets fire-safety codes for in-wall runs in residential buildings.
