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.\u003cbr\u003e\u003cbr\u003e12AWG 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.\u003cbr\u003e\u003cbr\u003eStandards: C(ETL)US Listed (Intertek) · CMR\/CL3R · FT4\u003cbr\u003e\u003cbr\u003e• Wire Gauge: 12AWG · Conductors: 2 (Red\/Black)\u003cbr\u003e• Conductor: Oxygen-Free Bare Copper (OFC) · Strands: 65 · Diameter: 0.01 in.\u003cbr\u003e• Conductor Resistance: 5.8 Ω\/1000ft\u003cbr\u003e• Insulation: PVC · Jacket: PVC CMR\/CL3R\/FT4 · Color: White\u003cbr\u003e• OD: 0.315 in. · Weight: 35 lbs · Rip Cord: Nylon\u003cbr\u003e• Packaging: 500ft Reelex II · Length: 500ft\u003c\/p\u003e","brand":"Big-A-Cables","offers":[{"title":"Riser","offer_id":46113072054506,"sku":"4048-Big","price":341.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0676\/6388\/8618\/files\/388598.jpg?v=1781902707","url":"https:\/\/bigacables.com\/products\/speaker-wire-12awg-2-conductor-ofc-stranded-cmr-500ft-white","provider":"Big-A-Cables","version":"1.0","type":"link"}
