Outdoor/Direct Burial Speaker Cable, Black, Pure Copper, CMR/CL3R, 16/2 (16 AWG 2 Conductor), 65 Strand / 0.16mm, Pullbox, 500 foot

Each conductor (wire) is composed of 65 0.16mm strands made from pure copper which provides the optimal conductivity/low resistance to drive high quality audio to your speakers Our speaker wire is made from pure copper Some companies use the marketing term oxygen free copper which really means there is no iron oxide in the wire When oxides of iron are in the copper, the conductivity of the wire reduces due to the higher resistance of the iron oxide
