18AWG 50ft oxygen-free copper speaker wire

This 18AWG speaker wire uses two conductors made from 99.95 percent pure oxygen-free bare copper. The cable is CL2 rated for in-wall installation in residential buildings and measures 50ft in length. Colour-coded PVC jackets on each conductor simplify polarity identification during setup.

Sustained signal integrity over distance

Pure bare copper keeps total cable resistance low so the amplifier sees a load close to the speaker impedance curve even on longer runs. The supplier notes that copper-clad aluminium alternatives are only about 68 percent as conductive, adding resistance that can alter frequency response. With this wire the resistance stays within the recommended 5 percent of the lowest speaker impedance.

CL2-rated in-wall installation limits

The CL2 rating confirms compliance with fire safety and insurance requirements for residential in-wall use. The black PVC outer jacket protects the conductors while meeting that standard. No other installation ratings or environmental certifications are supplied with this product.

Questions about this item

Does the 18AWG pure copper wire run warm when driving speakers all day?

The 18AWG oxygen-free copper conductors keep resistance low, so the cable stays cool even during extended high-volume sessions.

What terminals do my amplifier and speakers need for this 2-conductor cable?

The wire ends are bare copper; you will need binding posts, spring clips or banana plugs that accept bare wire.

Can I mix this 18AWG wire with the thinner cable already in my walls?

Yes, but keep total loop resistance under 5 percent of your speaker's lowest impedance to avoid audible loss.
