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 Vacuum Tube which is melted under non oxidizing conditions to get rid of oxygen and unalloyed copper to become pure copper to a grade of at least 99.95% cu and contain no more than .03% O2. The OFC 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 put 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 may then be considered oxygen-free copper.
The concept of IACS means International Annealed Copper Standard. Copper has become selected because the benchmark standard when comparing the electrical conductivity of metals, and is also the measurement standard that has been adopted worldwide.
The pure copper will be utilized to manufacture speaker cables, like OFC 99.95% and OFC 99.99% grades. For example, the speaker cable manufacturers will source pure copper in accordance with known standards respectively, including C10100 and C10200 standards.
High-fidelity speaker cables are very popular with 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 exists another metal utilised for speaker wire alongside RCA Cable. This really is silver which you’ll see occasionally manufactured with both silver and copper incorporated in twin-pairs of OFC speaker leads.
Silver has got the highest electrical conductivity and lowest resistance in the metallic family. Hence the electrical signals pass freely across the silver wires mostly unopposed, giving justification to a few audiophiles believing that enhanced audio is achieved when using silver speaker wires. Moreover silver wire will be designated for that negative polarity conductor and also the copper meant for the positive polarity conductor. However the vast majority of OFC speaker cables on the market utilise copper for the negative and positive conductors.
The actual 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 fxxwky OFC speaker wires are offered in various AWG sizes, including 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, in addition to, 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 their car audio systems.
In summary, pure copper OFC speaker wires are extremely good in transmitting beautiful audio sound for your ears. If you have a nice home theatre system with MUZISHARE then install OFC speaker cables and you’ll be amazed.
Nearly all audio surround systems and home theatre manufacturers built their electronic music devices to be operated with higher quality speaker cables. Hence to have the best from your sound system make sure you install OFC Speaker Wire.
