18AWG CL2 Speaker Wire 250ft

This 250ft reel of 18AWG CL2-rated speaker wire uses 99.95 percent pure oxygen-free copper conductors for low resistance. The two-conductor design suits stereo or multi-room audio runs inside walls or ceilings. White jacket aids identification during installation. Model 104046.

Ideal for in-wall stereo runs not needing heavy

Installers pulling wire through studs or joists for bookshelf or surround speakers will value the CL2 rating and oxygen-free copper. Buyers who need thicker conductors for very long distances or high-power amplifiers should consider a larger gauge. No connectors are included.

18AWG oxygen-free copper beats CCA at 68 percent

Pure bare copper delivers far lower resistance than copper-clad aluminium alternatives, preserving amplifier damping and frequency response. This single material advantage determines whether the wire suits critical listening or long cable pulls.

Questions about this item

What does the CL2 rating on this 18AWG speaker wire allow?

The CL2 rating means the cable is approved for in-wall installation in residential buildings, meeting fire-safety requirements for permanent runs.

What are the physical dimensions of the 250ft spool?

The spool contains 250 feet (76.2 metres) of white, two-conductor cable with 18AWG oxygen-free copper conductors and no pre-attached connectors.

How do you terminate this bare-copper speaker wire correctly?

Strip each conductor cleanly, twist the strands tightly, and secure them under the speaker or amplifier binding posts — loose strands cause shorts and the most common error is leaving stray whiskers.
