  • Electrical Outlet Plug TypeOthers
  • Pure copper delivers clearer sound
  • 95% oxygen-free copper reduces signal loss
  • 18AWG gauge handles longer runs efficiently
  • Lower resistance than copper-clad alternatives
  • 50ft spool suits multi-room installations

High-Purity Speaker Wire

This 18AWG oxygen-free copper speaker wire from Monoprice delivers clean signal transfer for home audio systems. The 50-foot length suits typical room layouts for stereo or surround installations. Pure bare copper conductors exceed 99.95 percent purity for low resistance.

Best for Standard Runs

Ideal for connecting bookshelf or floor-standing speakers to an amplifier at moderate distances. Builders needing longer continuous lengths or lower gauge for high-current applications should evaluate other options. The two-conductor design supports single-cable runs per speaker.

18AWG Conductor Gauge

The 18AWG thickness determines the safe run length before resistance affects speaker impedance. At this gauge, pure copper keeps total loop resistance well below the five-percent threshold for typical 8-ohm loads. Verify your distance and speaker impedance match this specification.

Questions about this item

Will this 18AWG oxygen-free copper wire work with my existing 8-ohm speakers without adding audible resistance?

Yes, the 99.95% pure copper conductors keep resistance low enough that total cable resistance stays well below 5% of speaker impedance, preserving the amplifier load curve.

How can I verify the wire is performing correctly after I connect it?

Measure continuity across each conductor with a multimeter; you should see near-zero resistance per 50-foot run, confirming the pure copper path is intact.

Does the 50-foot spool include connectors or banana plugs, or must I buy them separately?

The spool supplies only the bare two-conductor wire; terminations such as banana plugs, spade lugs or pin connectors are sold separately.
