Pure copper speaker wire for home audio

This 12AWG 4-conductor speaker wire uses oxygen-free 99.95 percent pure bare copper conductors. Pure copper conducts significantly better than copper-clad aluminium alternatives. The 250-foot spool provides ample length for multi-room installations. Model 104038 is designed for high-quality home audio systems.

Check CL2 rating and conductor count needed

Verify that your local building code accepts CL2-rated cable for in-wall residential runs. The white outer jacket carries this rating for safe installation inside walls. Confirm your speakers and amplifier require four conductors rather than two. Measure each run to ensure the 76.2-metre total length covers all zones.

Fits spool-based installs with standard terminals

The wire pays out from a spool for clean pulls through studs and conduit. Four conductors allow bi-wiring or a single cable run to a pair of speakers. Bare copper ends terminate under binding posts, banana plugs or spade lugs without special tools. No external power or active components are required.

Questions about this item

What comes in the box and do I need to buy connectors separately?

The box contains a single spool with 250 continuous feet of 12AWG 4-conductor speaker wire. No connectors are included, so you will need to purchase banana plugs, spades or pins separately if your equipment requires them.

Why choose the 12AWG 4-conductor version instead of a thinner or 2-conductor wire?

12AWG offers lower resistance over long runs, and four conductors let you wire two speakers or a bi-wire pair from one pull. The 99.95 percent pure oxygen-free copper conducts about 68 percent better than copper-clad aluminium alternatives.

What does the CL2 rating mean when the wire is installed inside walls?

The white outer jacket carries a CL2 rating, which means it meets fire-safety standards for in-wall installation in residential buildings. You can run the 76.2 metre spool through stud cavities without needing additional conduit.
