OFC is abbreviated from the term Oxygen-Free Copper and is associated with top 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 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 numerous stages until it reaches 99% purity. Then this copper is placed in anodes to get refined electrolytically to some grade of at the very least 99.95% pure copper. On finishing of the aforementioned processes the copper wires can then be classified as oxygen-free copper.
The definition of IACS is short for International Annealed Copper Standard. Copper has been selected because the benchmark standard when comparing the electrical conductivity of metals, and is the measurement standard that has been adopted worldwide.
The pure copper is then 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 based on known standards respectively, such as 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. This is why many audiophiles select OFC speaker wires for his or her preferred high fidelity cabling in audio systems.
There exists another metal utilised for speaker wire alongside copper on the market. This can be silver which you’ll see occasionally manufactured with both silver and copper incorporated in twin-pairs of Audiophile Cables.
Silver has got the highest electrical conductivity and lowest resistance from the metallic family. Hence the electrical signals pass freely over the silver wires mostly unopposed, giving justification to a few audiophiles believing that enhanced audio is achieved when utilizing silver speaker wires. Moreover silver wire will be designated for your negative polarity conductor and the copper meant for the positive polarity conductor. However the majority of OFC speaker cables on the market utilise copper for both the negative and positive conductors.
The actual gauge (diameter) of the copper wires is normally described using the American Wire Gauge (AWG) measurement system. The AWG measurement system is commonly used amongst OFC speaker cable sellers. Furthermore the OFC speaker wires can be bought in several AWG sizes, such as 22AWG, 18AWG, 16AWG, 13AWG, 11AWG, 9AWG etc.
Manufacturers like SoundLink manufacturer numerous the AWG sizes mentioned previously. SoundLink construct the OFC speaker cables with clear see-through jackets, as well as, in round wire shape along with a flat wire contour around neatly fit under carpet. The flat-designed OFC speaker cable can then be laid inside automobiles for their car audio systems.
In summary, pure copper OFC speaker wires are extremely good in transmitting beautiful audio sound for 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 blown away.
Nearly all audio surround systems and home theatre manufacturers built their electronic music devices to be operated with high quality speaker cables. Hence to get the most from your sound system make certain you install Line Magnetic 219ia.
