OFC is abbreviated from the term Oxygen-Free Copper and is associated with good quality speaker wires because of the 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 become pure copper to a grade of at least 99.95% cu and contain not more than .03% O2. The Cayin A100t 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 positioned in anodes to be refined electrolytically to your grade of a minimum of 99.95% pure copper. On completion of the aforementioned processes the copper wires can then be classified as oxygen-free copper.
The definition of IACS means International Annealed Copper Standard. Copper has become selected since 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 will be utilized to manufacture speaker cables, such as OFC 99.95% and OFC 99.99% grades. As an example, the speaker cable manufacturers will source pure copper based on known standards respectively, like C10100 and C10200 standards.
High-fidelity speaker cables are extremely popular with audiophile enthusiasts since the accuracy of audio signals, are reproduced immensely well with high-fidelity cables. This is the reason many audiophiles select OFC speaker wires for 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 XLR Cable.
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 some audiophiles believing that enhanced audio is achieved when you use silver speaker wires. Moreover silver wire will likely be designated for your 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 particular gauge (diameter) from the copper wires is typically referred to using the American Wire Gauge (AWG) measurement system. The AWG measurement system is widely used amongst OFC speaker cable sellers. Furthermore the OFC speaker wires are offered in numerous AWG sizes, including 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 their car audio systems.
In summary, pure copper OFC speaker wires are incredibly good in transmitting beautiful audio sound to your ears. In case you have a nice 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 get operated with high quality speaker cables. Hence to obtain the best from your sound system make certain you install Line Magnetic.
