OFC is abbreviated from the term Oxygen-Free Copper and is associated with top 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 a maximum of .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 this copper is put in anodes to get refined electrolytically to a grade of at least 99.95% pure copper. On completion of the previously mentioned processes the copper wires can then be considered oxygen-free copper.
The definition of IACS means International Annealed Copper Standard. Copper has been selected as 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 used to manufacture speaker cables, such as OFC 99.95% and OFC 99.99% grades. For instance, the speaker cable manufacturers will source pure copper based on known standards respectively, such as C10100 and C10200 standards.
High-fidelity speaker cables are very well-liked by audiophile enthusiasts because the accuracy of audio signals, are reproduced immensely well rich in-fidelity cables. For this reason many audiophiles select OFC speaker wires for his or her preferred high fidelity cabling in audio systems.
There exists 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 XLR Cable.
Silver has the highest electrical conductivity and lowest resistance in 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 utilizing silver speaker wires. Moreover silver wire will likely be designated for the negative polarity conductor as well as 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 actual gauge (diameter) of the copper wires is usually known as utilizing 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 several AWG sizes, such as 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 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 very good in transmitting beautiful audio sound for your ears. In case you have a great home theatre system with digital Dolby Digital and 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 high quality speaker cables. Hence to have the most out of your sound system make sure you install Line Magnetic 219ia.
