4-Conductor 16AWG Speaker Wire

This 250-foot spool of 16AWG speaker wire contains four conductors made from oxygen-free bare copper with a purity greater than 99.95 percent. The CL2-rated jacket allows in-wall installation for whole-home audio systems. It suits installers running multi-room or bi-wire speaker connections.

Installation notes

Each conductor is individually jacketed in colour-coded PVC for straightforward polarity identification during termination. The outer black PVC jacket carries a CL2 fire-safety rating for code-compliant in-wall runs. The pure copper conductors are more flexible than copper-clad aluminium alternatives, reducing kinking when pulled through studs.

Conductor purity

The four conductors use bare copper exceeding 99.95 percent purity, which is substantially more conductive than the copper-clad aluminium found in budget wire. Lower resistance keeps the amplifier load closer to the speaker impedance curve across frequencies. Choose this wire when conductor material purity is the deciding factor for your installation.

Questions about this item

How can I confirm the wire is performing correctly after installation?

Measure the total loop resistance with a multimeter; it should stay well below five percent of your speaker's lowest impedance so the amplifier sees the intended load.

What does the 250-foot spool include and what must I supply?

The spool provides four 16AWG oxygen-free bare copper conductors in a CL2-rated black PVC jacket with color-coded insulation; you add connectors, banana plugs or bare-wire terminations yourself.

When should I choose this 16AWG four-conductor version over other gauges?

Select this gauge for runs up to about 50 feet per speaker with 8-ohm loads; thicker wire is only needed for longer distances or lower-impedance speakers.
