Monoprice Choice Series 12AWG Oxygen-Free Pure Bare Copper Speaker Wire 100ft

Description

Even speakers rated for a nominal 8-ohms, may dip to as low as 4-ohms at some frequencies, which further reduces the total cable resistance allowed in the wire. 20 feet of 16AWG Pure Bare Copper would be 0.1606 ohms, well under the 0.2-ohm limit. Assuming 4 ohms is the lowest impedance of your speakers, a speaker wire run can be no more 0.2-ohms total. For example, a 16AWG 2-conductor Pure Bare Copper speaker wire has a total resistance of 0.803 ohms per 100 feet (both directions must be considered). By comparison, a 16AWG 2-conductor CCA speaker wire has a total resistance of 1.181 ohms per 100 feet. CCA is only about 68% as conductive as pure bare copper. For example, a 16AWG 2-conductor Pure Bare Copper speaker wire has a total resistance of 0.803 ohms per 100 feet (both directions must be considered). Pure Bare Copper is a conductor to the copper clad aluminum (CCA) conductors used in most other inexpensive speaker wire. This additional resistance is added to the impedance of your speakers and can negatively effect the sound. Using Pure Bare Copper speaker wire ensures that the total load put on the amplifier remains as close as possible to the impedance curve of your speakers. By comparison, a 16AWG 2-conductor CCA speaker wire has a total resistance of 1.181 ohms per 100 feet. For the wire to have no audible effect, the total wire resistance should be no more than 5% of the lowest impedance of your speakers.

Key Features

• This speaker wire features two conductors made of high purity (greater than 99.95% pure), oxygen-free bare copper.
• Pure Bare Copper is a conductor to the copper clad aluminum (CCA) conductors used in most other inexpensive speaker wire.
• 20 feet of 16AWG Pure Bare Copper would be 0.1606 ohms, well under the 0.2-ohm limit.
• On the other hand, 20 feet of 16AWG CCA would be 0.2362 ohms, well OVER the 0.2-ohm limit.
• By comparison, a 16AWG 2-conductor CCA speaker wire has a total resistance of 1.181 ohms per 100 feet.
• For example, a 16AWG 2-conductor Pure Bare Copper speaker wire has a total resistance of 0.803 ohms per 100 feet (both directions must be considered).
