12 AWG Oxygen-Free Copper Speaker Wire

This 12 AWG speaker wire uses two conductors made from greater than 99.95 percent pure oxygen-free bare copper. It is designed for home audio systems where low resistance preserves the amplifier's impedance curve. The black PVC jacket carries a CL2 rating for in-wall installation in residential buildings.

Capacity and resistance headroom

Pure bare copper conductivity avoids the added resistance of copper-clad aluminium, which is only 68 percent as conductive. Keeping total wire resistance below 5 percent of the speaker's lowest impedance prevents audible degradation, especially when nominal 8-ohm speakers dip to 4 ohms. The 30.48 metre length suits whole-room runs without excessive loss.

CL2 in-wall rating and polarity limits

The CL2-rated jacket meets fire safety and insurance requirements for installation inside residential walls. Color-coded PVC on each conductor allows quick polarity identification during termination. The two-conductor design supports single amplifier-to-speaker runs only and does not carry bi-wire or multi-channel configurations.

Questions about this item

Will this 12AWG oxygen-free copper wire work with my older 8-ohm speakers?

Yes, the 12AWG pure bare copper conductors keep resistance well below the 5 percent threshold recommended for 8-ohm speakers, even when impedance dips to 4 ohms.

How can I verify the polarity is correct after running the cable inside the wall?

Each conductor has a colour-coded PVC jacket so you can visually confirm positive and negative connections at both ends.

Does the 100ft CL2-rated spool include connectors or banana plugs?

The box contains only the raw 2-conductor cable; terminations such as banana plugs or spade connectors must be purchased separately.
