OFC is abbreviated from the term Oxygen-Free Copper and is associated with top quality speaker wires due to their excellent conductivity and ductility. Oxygen-Free Copper (OFC) cables are highly conductive pure copper which is melted under non oxidizing conditions to remove oxygen and unalloyed copper to get pure copper to a grade of at least 99.95% cu and contain a maximum of .03% O2. The Cayin Audio ability for electrical conductivity must exceed IACS 100% material rating system.
The melting of copper is performed in several stages until it reaches 99% purity. Then the copper is positioned in anodes to get refined electrolytically to a grade of a minimum of 99.95% pure copper. On finishing of the aforementioned processes the copper wires can then be considered oxygen-free copper.
The concept of IACS means International Annealed Copper Standard. Copper has been selected since the benchmark standard when you compare the electrical conductivity of metals, and is also the measurement standard that has been adopted worldwide.
The pure copper will then be used to manufacture speaker cables, such as OFC 99.95% and OFC 99.99% grades. For example, the speaker cable manufacturers will source pure copper in accordance with known standards respectively, like C10100 and C10200 standards.
High-fidelity speaker cables are very popular with audiophile enthusiasts since the accuracy of audio signals, are reproduced immensely well rich in-fidelity cables. This is the reason many audiophiles select OFC speaker wires for preferred high fidelity cabling in audio systems.
There exists another metal utilised for speaker wire alongside copper on the market. This is silver which you’ll see occasionally manufactured with both silver and copper incorporated in twin-pairs of Audiophile Cables.
Silver provides the highest electrical conductivity and lowest resistance from the metallic family. Hence the electrical signals pass freely along the silver wires mostly unopposed, giving justification for some audiophiles believing that enhanced audio is achieved when using silver speaker wires. Moreover silver wire will be designated for that negative polarity conductor and the copper meant for the positive polarity conductor. However the vast majority of OFC speaker cables on the market utilise copper for the negative and positive conductors.
The actual gauge (diameter) in the copper wires is usually known as utilizing the American Wire Gauge (AWG) measurement system. The AWG measurement product is commonly used amongst OFC speaker cable sellers. Furthermore the OFC speaker wires are offered in various AWG sizes, such as 22AWG, 18AWG, 16AWG, 13AWG, 11AWG, 9AWG etc.
Manufacturers like SoundLink manufacturer a multitude of the AWG sizes mentioned previously. SoundLink construct the OFC speaker cables with clear see-through jackets, as well as, in round wire shape and a flat wire shape to neatly fit under carpet. The flat-designed OFC speaker cable can then be laid inside automobiles for car audio systems.
To conclude, pure copper OFC speaker wires are incredibly good in transmitting beautiful audio sound for your ears. If you have a good home theatre system with digital Dolby Digital and quality speakers then install OFC speaker cables gaqgbw you’ll be very impressed.
Nearly all audio surround systems and home theatre manufacturers built their electronic music devices to get operated with high quality speaker cables. Hence to get the most out of your sound system ensure you install Line Magnetic.
