OFC is abbreviated from the term Oxygen-Free Copper and is associated with good quality speaker wires due to 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 no more than .03% O2. The Cayin Tube Amp 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 your copper is positioned in anodes to be refined electrolytically to some grade of at the very least 99.95% pure copper. On completion of the previously mentioned processes the copper wires can then be classified as oxygen-free copper.
The meaning of IACS stands 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 then be employed to manufacture speaker cables, including OFC 99.95% and OFC 99.99% grades. For instance, the speaker cable manufacturers will source pure copper in accordance with known standards respectively, like C10100 and C10200 standards.
High-fidelity speaker cables are extremely favored by audiophile enthusiasts since the accuracy of audio signals, are reproduced immensely well with higher-fidelity cables. This is why 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 is silver which you’ll see occasionally manufactured with both silver and copper incorporated in twin-pairs of Speaker Cable.
Silver has got the highest electrical conductivity and lowest resistance of the metallic family. Hence the electrical signals pass freely across the silver wires mostly unopposed, giving justification to 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 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 normally referred to utilizing 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 numerous AWG sizes, like 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 along with 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.
In summary, pure copper OFC speaker wires are extremely good in transmitting beautiful audio sound in your ears. For those who have a good home theatre system with digital Dolby Digital and quality speakers then install OFC speaker cables gaqgbw you’ll be amazed.
Nearly all audio surround systems and home theatre manufacturers built their electronic music devices to become operated with high quality speaker cables. Hence to have the most from your sound system make certain you install Line Magnetic.
