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 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 not more than .03% O2. The Cayin 300B 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 the copper is put in anodes to be refined electrolytically to some grade of a minimum of 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 is short for International Annealed Copper Standard. Copper has become selected as the benchmark standard when you compare the electrical conductivity of metals, and is the measurement standard which has been adopted worldwide.
The pure copper will then be used to manufacture speaker cables, like OFC 99.95% and OFC 99.99% grades. As an example, the speaker cable manufacturers will source pure copper according to known standards respectively, including C10100 and C10200 standards.
High-fidelity speaker cables are very favored by audiophile enthusiasts because the accuracy of audio signals, are reproduced immensely well with high-fidelity cables. This is why many audiophiles select OFC speaker wires for his or her preferred high fidelity cabling in audio systems.
There is certainly 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 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 to a few audiophiles believing that enhanced audio is achieved when utilizing silver speaker wires. Moreover silver wire is going to be designated for your negative polarity conductor and also the copper intended for the positive polarity conductor. However nearly all OFC speaker cables on the market utilise copper for both the negative and positive conductors.
The actual gauge (diameter) from the copper wires is normally referred to making use of the American Wire Gauge (AWG) measurement system. The AWG measurement method is commonly used amongst OFC speaker cable sellers. Furthermore the OFC speaker wires are sold in various AWG sizes, like 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 as well as a flat wire contour around 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 in your ears. In case 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.
The majority of audio surround systems and home theatre manufacturers built their electronic music devices to get operated rich in quality speaker cables. Hence to have the most out of your sound system ensure you install Line Magnetic 218ia.
