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 conducted in numerous stages until it reaches 99% purity. Then the copper is positioned in anodes to get refined electrolytically to a grade of at least 99.95% pure copper. On finishing of the previously mentioned processes the copper wires can then be classified as oxygen-free copper.
The concept of IACS stands for International Annealed Copper Standard. Copper has become selected because the benchmark standard when you compare the electrical conductivity of metals, and is also the measurement standard which has been adopted worldwide.
The pure copper is then utilized to manufacture speaker cables, like OFC 99.95% and OFC 99.99% grades. As an 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 incredibly popular with audiophile enthusiasts because the accuracy of audio signals, are reproduced immensely well with higher-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 can be silver which you’ll see occasionally manufactured with both silver and copper incorporated in twin-pairs of Speaker 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 you use silver speaker wires. Moreover silver wire will be designated for the negative polarity conductor and also the copper designed for the positive polarity conductor. However the majority of OFC speaker cables on the market utilise copper for the negative and positive conductors.
The particular gauge (diameter) in the copper wires is typically described using 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 numerous 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 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 their car audio systems.
In conclusion, pure copper OFC speaker wires are extremely good in transmitting beautiful audio sound for your ears. In case you have a great home theatre system with digital Dolby Digital and high quality speakers then install OFC speaker cables gaqgbw you’ll be very impressed.
The vast majority of audio surround systems and home theatre manufacturers built their electronic music devices to become operated rich in quality speaker cables. Hence to obtain the best from your sound system make certain you install Line Magnetic 518ia.
