  • Product colorBlack
  • Overall length304.8
  • Key features4 conductors made of high purity (greater than 99.95 percent
  • High-purity oxygen-free copper (99.95% pure) reduces resistance for cleaner signal transfer
  • Four conductors allow bi-wiring or dual-zone runs from a single cable pull
  • CL2-rated PVC jacket meets in-wall fire safety codes for permanent installation
  • Colour-coded conductor jackets simplify polarity identification during setup
  • 1000 ft (304.8 m) reel provides ample length for whole-house audio projects

Application & Audience

Monoprice 141399 is a 1000ft spool of 14AWG speaker wire built for whole-home audio installs and professional low-voltage runs. The four-conductor design lets installers pull a single cable for stereo pairs or bi-wire configurations. CL2-rated jacket meets in-wall fire codes for residential and light-commercial projects.

Build Integration

Four colour-coded PVC jackets simplify polarity identification at every termination point. Oxygen-free bare copper conductors keep resistance low so amplifier loading stays close to the speaker impedance curve. CL2-rated outer sheath allows direct routing through stud bays without conduit in most jurisdictions.

Sustained Performance

Conductors exceed 99.95 percent purity, delivering conductivity far above the 68 percent typical of copper-clad aluminium alternatives. Lower resistance prevents audible losses on long runs where total cable resistance must remain a small fraction of speaker impedance. Pure bare copper maintains consistent electrical behaviour during extended high-power playback.

Questions about this item

How does the 14 AWG pure copper construction limit resistance on long runs?

The four 14 AWG conductors use 99.95 percent pure oxygen-free copper, keeping total wire resistance well below the five-percent-of-speaker-impedance threshold that causes audible loss on 1000 ft pulls.

Does the CL2-rated PVC jacket handle heat from all-day amplifier loads?

The CL2-rated black PVC jacket is rated for in-wall installation and resists the modest heat produced by typical speaker-level currents running continuously.

What amplifier terminals accept the bare 4-conductor ends?

Any binding-post, spring-clip or banana-plug terminal that takes bare 14 AWG wire will connect directly to the color-coded PVC-jacketed conductors.
