OFC is abbreviated from the term Oxygen-Free Copper and is associated with high quality speaker wires because of their excellent conductivity and ductility. Oxygen-Free Copper (OFC) cables are highly conductive pure copper that is melted under non oxidizing conditions to remove oxygen and unalloyed copper to become pure copper to a grade of at least 99.95% cu and contain no more than .03% O2. The Cayin A100t ability for electrical conductivity must exceed IACS 100% material rating system.
The melting of copper is carried out in numerous stages until it reaches 99% purity. Then your copper is put in anodes to become refined electrolytically to a grade of at the very least 99.95% pure copper. On finishing of the previously mentioned processes the copper wires can then be classified as oxygen-free copper.
The definition of IACS is short for International Annealed Copper Standard. Copper continues to be selected as the benchmark standard when comparing the electrical conductivity of metals, and it is the measurement standard that has been adopted worldwide.
The pure copper will be used to manufacture speaker cables, including OFC 99.95% and OFC 99.99% grades. For example, the speaker cable manufacturers will source pure copper based on known standards respectively, including C10100 and C10200 standards.
High-fidelity speaker cables are extremely popular with audiophile enthusiasts since the accuracy of audio signals, are reproduced immensely well rich in-fidelity cables. For this reason many audiophiles select OFC speaker wires for his or her preferred high fidelity cabling in audio systems.
There is another metal utilised for speaker wire alongside copper on the market. This really is silver which you’ll see occasionally manufactured with both silver and copper incorporated in twin-pairs of CopperColour Cable.
Silver has the highest electrical conductivity and lowest resistance in the metallic family. Hence the electrical signals pass freely along the silver wires mostly unopposed, giving justification to a few 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 designed for the positive polarity conductor. However nearly all OFC speaker cables on the market utilise copper for both the negative and positive conductors.
The specific gauge (diameter) of the copper wires is normally described making use of the American Wire Gauge (AWG) measurement system. The AWG measurement system is commonly used amongst OFC speaker cable sellers. Furthermore the OFC speaker wires are offered in various AWG sizes, including 22AWG, 18AWG, 16AWG, 13AWG, 11AWG, 9AWG etc.
Manufacturers like SoundLink manufacturer a wide variety of the AWG sizes mentioned previously. SoundLink construct the OFC speaker cables with clear see-through jackets, as well as, in round wire shape as well as a flat wire shape to neatly fit under carpet. The flat-designed OFC speaker cable can then be laid inside automobiles for his or her car audio systems.
In summary, pure copper OFC speaker wires are very good in transmitting beautiful audio sound in your ears. If you have a nice home theatre system with digital Dolby Digital and high quality speakers then install OFC speaker cables gaqgbw you’ll be amazed.
The majority of audio surround systems and home theatre manufacturers built their electronic music devices to become operated rich in quality speaker cables. Hence to get the most from your sound system make sure you install Line Magnetic 218ia.
