OFC is abbreviated from the term Oxygen-Free Copper and is associated with top quality speaker wires because of their excellent conductivity and ductility. Oxygen-Free Copper (OFC) cables are highly conductive pure copper which 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 a number of stages until it reaches 99% purity. Then your copper is placed in anodes to be 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 definition of IACS stands for International Annealed Copper Standard. Copper has been selected as the benchmark standard when comparing the electrical conductivity of metals, and is the measurement standard which has been adopted worldwide.
The pure copper will then 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 according to known standards respectively, like 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 higher-fidelity cables. For this reason many audiophiles select OFC speaker wires for preferred high fidelity cabling in audio systems.
There is another metal utilised for speaker wire alongside copper on the market. This can be silver which you’ll see occasionally manufactured with both silver and copper incorporated in twin-pairs of CopperColour Cable.
Silver provides the highest electrical conductivity and lowest resistance from the metallic family. Hence the electrical signals pass freely along the silver wires mostly unopposed, giving justification to some audiophiles believing that enhanced audio is achieved when you use silver speaker wires. Moreover silver wire will be designated for your negative polarity conductor as well as the copper intended for the positive polarity conductor. However nearly all OFC speaker cables on the market utilise copper for the negative and positive conductors.
The specific gauge (diameter) in the copper wires is typically described using the American Wire Gauge (AWG) measurement system. The AWG measurement product is widely used amongst OFC speaker cable sellers. Furthermore the OFC speaker wires are sold in numerous AWG sizes, like 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 his or her car audio systems.
In conclusion, pure copper OFC speaker wires are very good in transmitting beautiful audio sound in 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 very impressed.
Nearly all audio surround systems and home theatre manufacturers built their electronic music devices to be operated rich in quality speaker cables. Hence to obtain the most from your sound system make sure you install Line Magnetic 218ia.
