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 not more than .03% O2. The Cayin Tube Amp ability for electrical conductivity must exceed IACS 100% material rating system.
The melting of copper is carried out in several stages until it reaches 99% purity. Then the copper is placed in anodes to get refined electrolytically to some grade of at the very least 99.95% pure copper. On completion of the aforementioned processes the copper wires can then be classified as oxygen-free copper.
The concept of IACS stands for International Annealed Copper Standard. Copper has been selected since the benchmark standard when comparing the electrical conductivity of metals, and it is the measurement standard which has been adopted worldwide.
The pure copper will then be employed to manufacture speaker cables, including OFC 99.95% and OFC 99.99% grades. As an 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 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 is silver which you’ll see occasionally manufactured with both silver and copper incorporated in twin-pairs of CopperColour Cable.
Silver provides the highest electrical conductivity and lowest resistance of the metallic family. Hence the electrical signals pass freely along 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 likely be designated for the negative polarity conductor and the copper intended for the positive polarity conductor. However the vast majority of OFC speaker cables on the market utilise copper for both the negative and positive conductors.
The specific gauge (diameter) in the copper wires is normally known as utilizing the American Wire Gauge (AWG) measurement system. The AWG measurement method is widely 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 and 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.
In summary, pure copper OFC speaker wires are very 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 amazed.
The vast majority of audio surround systems and home theatre manufacturers built their electronic music devices to become operated with higher quality speaker cables. Hence to obtain the most out of your sound system make certain you install Line Magnetic 518ia.
