Description

Wire your home theater, multi-room audio, or commercial background music system with this 12AWG 2-conductor OFC in-wall speaker wire. CMR and CL3R rated, it is approved for permanent in-wall and riser installations in residential and commercial buildings, with the lowest resistance per foot of any standard in-wall speaker wire gauge.

12AWG OFC is the go-to choice for high-power installations: 4-ohm speaker loads, amplifiers over 100 watts, and long in-wall runs from 50 to 200 feet where thinner 14AWG or 16AWG wire would add measurable resistance and audible power loss. 65 strands of oxygen-free bare copper per conductor keep the wire flexible for routing through walls, around corners, and into wall plates without kinking. OFC conductors resist oxidation at connection points — maintaining low resistance over the life of the installation. Color-coded insulation (Red = positive, Black = negative) makes polarity fast and mistake-free at every termination.
