OFC is abbreviated from the term Oxygen-Free Copper and is associated with good 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 a maximum of .03% O2. The Cayin A88t Mk2 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 your grade of a minimum of 99.95% pure copper. On finishing of the aforementioned processes the copper wires can then be classified as oxygen-free copper.
The concept of IACS is short for International Annealed Copper Standard. Copper has become selected since the benchmark standard when you compare the electrical conductivity of metals, and it is 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. As an example, the speaker cable manufacturers will source pure copper according to known standards respectively, such as C10100 and C10200 standards.
High-fidelity speaker cables are very popular with audiophile enthusiasts since the accuracy of audio signals, are reproduced immensely well with high-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 Speaker Cable.
Silver provides 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 a few audiophiles believing that enhanced audio is achieved when utilizing silver speaker wires. Moreover silver wire will likely be designated for the negative polarity conductor and the copper designed 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) of the copper wires is normally described 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 various 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 extremely good in transmitting beautiful audio sound for 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.
Nearly all audio surround systems and home theatre manufacturers built their electronic music devices to become operated with higher quality speaker cables. Hence to get the most from your sound system make certain you install Line Magnetic.
