Get the most out of your home audio system with high quality oxygen-free pure bare copper speaker wire from Tech Choice. This speaker wire features two conductors made of high purity (greater than 99.95% pure) oxygen-free bare copper. Pure Bare Copper is a superior conductor to the copper clad aluminum (CCA) conductors used in most other inexpensive speaker wire. CCA is only about 68% as conductive as pure bare copper.
- Cable Type: Loudspeaker cable
- 20 feet of 16AWG CCA would be 0.2362 ohms, well over the 0.2-ohm limit
- A 16 AWG 2-conductor CCA speaker wire has a total resistance of 1.181 ohms per 100 feet
- 20 feet of 16 AWG Pure Bare Copper would be 0.1606 ohms, well under the 0.2-ohm limit
