SKU CH-18GG-R7YAK

12 AWG oxygen-free copper speaker wire on a 300 ft spool with CL2 rating and polarity stripe

  • Oxygen-free 99.95% pure copper conductors minimise resistance
  • 12AWG gauge handles longer runs with lower loss
  • 300 continuous feet on a spool suits whole-home installs
  • CL2-rated jacket meets in-wall fire-safety codes
  • Blue polarity stripe on clear PVC simplifies correct connections

Oxygen-Free 12AWG Speaker Wire

This 300-foot spool delivers 12AWG two-conductor cable built from 99.95 percent pure oxygen-free bare copper. It is designed for home audio installations where low resistance and accurate signal transfer matter. The CL2 rating allows in-wall routing for permanent setups. A blue polarity stripe on the clear PVC jacket simplifies correct connections.

Low Resistance and Heat Performance

Pure bare copper conductors keep total loop resistance near 0.803 ohms per 100 feet, far below the 68 percent conductivity of copper-clad alternatives. Lower resistance reduces power lost as heat and keeps the amplifier load close to the speaker impedance curve. The flexible jacket withstands normal installation pulls without stiffening or cracking over time.

Build Integration and Polarity Aid

The 300-foot continuous length covers multi-room runs without splices that add resistance. CL2 compliance meets common building codes for in-wall placement. The visible blue stripe on one conductor eliminates guesswork during termination at speakers and amplifiers. No special tools are required beyond standard wire strippers and connectors.
