16AWG Oxygen-Free Copper Speaker Wire

This 16AWG speaker wire uses two conductors of 99.95 percent pure oxygen-free bare copper. It is built for home audio installations where low resistance matters. The CL2 rating makes it suitable for in-wall runs in residential buildings. It arrives in a 250-foot pull for multi-room projects.

CL2-Rated In-Wall Installation

The black PVC jacket carries a CL2 fire-safety rating, so the cable meets code for routing inside walls. Each conductor has colour-coded PVC insulation for quick polarity identification. The wire feeds speakers from an amplifier or receiver without needing conduit. No connectors are included; termination is left to the installer.

Sustained Signal Integrity

Pure bare copper keeps resistance far below the five-percent threshold that can alter speaker impedance curves. Unlike copper-clad aluminium at roughly 68 percent conductivity, this wire maintains consistent load on the amplifier during extended playback. The oxygen-free construction resists oxidation that would increase resistance over time.

  • 16 AWG gauge keeps cable loss below 5% of speaker impedance
  • CL2 rating approved for in-wall residential installation
  • Colour-coded PVC jackets simplify polarity identification
  • 250 ft spool supplies long runs without splices

Questions about this item

How does the 16AWG pure bare copper wire limit resistance under sustained high-power use?

The 99.95 percent pure oxygen-free copper keeps resistance far below the 5 percent threshold of speaker impedance, preventing the power loss and sound degradation that copper-clad aluminum adds at 68 percent conductivity.

Does the CL2-rated PVC jacket handle heat buildup during all-day playback?

The CL2 rating certifies the black PVC jacket for in-wall fire safety, meaning it meets building-code temperature limits for continuous operation inside residential walls.

What amplifier terminals are needed for the two color-coded conductors?

Each conductor uses standard bare-wire ends that connect to any binding post, spring clip or banana plug accepting 16AWG speaker cable.
