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 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 no more than .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 be refined electrolytically to a grade of at the very 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 is short for International Annealed Copper Standard. Copper has become selected because the benchmark standard when comparing the electrical conductivity of metals, and is the measurement standard that has been adopted worldwide.
The pure copper will then be employed to manufacture speaker cables, like OFC 99.95% and OFC 99.99% grades. As an example, the speaker cable manufacturers will source pure copper based on known standards respectively, including C10100 and C10200 standards.
High-fidelity speaker cables are incredibly favored by audiophile enthusiasts since 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 is certainly another metal utilised for speaker wire alongside copper on the market. This really is silver which you’ll see occasionally manufactured with both silver and copper incorporated in twin-pairs of Speaker Cable.
Silver has got the highest electrical conductivity and lowest resistance of the metallic family. Hence the electrical signals pass freely over the silver wires mostly unopposed, giving justification for some audiophiles believing that enhanced audio is achieved when using silver speaker wires. Moreover silver wire will be designated for your negative polarity conductor and the copper meant 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 typically described using the American Wire Gauge (AWG) measurement system. The AWG measurement system is popular amongst OFC speaker cable sellers. Furthermore the 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, as well as, 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 car audio systems.
In conclusion, pure copper OFC speaker wires are extremely 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 blown away.
The vast majority of audio surround systems and home theatre manufacturers built their electronic music devices to become operated rich in quality speaker cables. Hence to obtain the best from your sound system make sure you install Line Magnetic 219ia.
