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 get pure copper to a grade of at least 99.95% cu and contain a maximum of .03% O2. The Cayin 300B ability for electrical conductivity must exceed IACS 100% material rating system.
The melting of copper is conducted in several stages until it reaches 99% purity. Then the copper is placed in anodes to become refined electrolytically to your grade of a minimum of 99.95% pure copper. On completing the aforementioned processes the copper wires can then be classified as oxygen-free copper.
The definition of IACS stands for International Annealed Copper Standard. Copper continues to be 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 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 incredibly favored by audiophile enthusiasts considering that the accuracy of audio signals, are reproduced immensely well rich in-fidelity cables. For this reason many audiophiles select OFC speaker wires for their 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 has the highest electrical conductivity and lowest resistance from the metallic family. Hence the electrical signals pass freely across the silver wires mostly unopposed, giving justification for some audiophiles believing that enhanced audio is achieved when using silver speaker wires. Moreover silver wire is going to be designated for that negative polarity conductor as well as the copper meant for the positive polarity conductor. However nearly all OFC speaker cables on the market utilise copper for the negative and positive conductors.
The particular gauge (diameter) of the copper wires is usually described making use of the American Wire Gauge (AWG) measurement system. The AWG measurement product is commonly 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 multitude of 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 extremely good in transmitting beautiful audio sound for your ears. If you have a good home theatre system with digital Dolby Digital and quality speakers then install OFC speaker cables gaqgbw you’ll be blown away.
The majority of audio surround systems and home theatre manufacturers built their electronic music devices to be operated rich in quality speaker cables. Hence to get the best from your sound system make sure you install Line Magnetic.
