What Are OFC Speaker Cables and Why Do Some OFC Wires Have Silver and Copper?

OFC is abbreviated from the time period Oxygen-No cost Copper and is associated with large excellent speaker wires because of their fantastic conductivity and ductility.

Oxygen-Cost-free Copper (OFC) cables are hugely conductive pure copper that is melted underneath non oxidizing disorders to take away oxygen and unalloyed copper to grow to be pure copper to a grade of at minimum 99.95% cu and incorporate no extra than .03% O2. The OFC capability for electrical conductivity must exceed IACS 100% substance ranking system.

The melting of copper is executed in many phases until eventually it reaches 99% purity. Then the copper is put in anodes to be refined electrolytically to a grade of at the very least 99.95% pure copper. On completion of the aforementioned procedures the copper wires can then be labeled as oxygen-totally free copper.

The definition of IACS stands for Global Annealed Copper Common. Copper has been chosen as the benchmark standard when evaluating the electrical conductivity of metals, and is the measurement common that has been adopted worldwide.

The pure copper is then applied to manufacture speaker cables, such as OFC 99.95% and OFC 99.99% grades. For occasion, the speaker cable manufacturers will supply pure copper according to acknowledged standards respectively, this sort of as C10100 and C10200 standards.

High-fidelity speaker cables are incredibly well-known with audiophile lovers considering the fact that the precision of audio signals, are reproduced immensely very well with large-fidelity cables. This is why quite a few audiophiles find OFC speaker wires for their most popular substantial fidelity cabling in audio methods.

There is one more metal utilised for speaker wire alongside copper on the market place. This is silver which you can see often produced with both silver and copper integrated in twin-pairs of OFC speaker sales opportunities.

Silver has the highest electrical conductivity and lowest resistance of the metallic loved ones. As a result the electrical indicators move freely together the silver wires largely unopposed, giving justification to some audiophiles believing that improved audio is realized when employing silver speaker wires. In addition silver wire will be designated for the damaging polarity conductor and the copper supposed for the positive polarity conductor. However the the vast majority of OFC speaker cables on the market place utilise copper for both equally the detrimental and good conductors.

The true gauge (diameter) of the copper wires is normally referred to working with the American Wire Gauge (AWG) measurement technique. The AWG measurement procedure is commonly used among OFC speaker cable sellers. Moreover the OFC speaker wires are bought in numerous AWG sizes, such as 22AWG, 18AWG, 16AWG, 13AWG, 11AWG, 9AWG and so forth.

Producers like SoundLink producer a wide wide range of the AWG sizes talked about formerly. SoundLink assemble the OFC speaker cables with obvious see-by way of jackets, as properly as, in round wire condition and a flat wire form to neatly in shape beneath carpet. The flat-intended OFC speaker cable can then be laid inside automobiles for their motor vehicle audio techniques.

In summary, pure copper OFC speaker wires are pretty superior in transmitting lovely audio audio to your ears. If you have a awesome household theatre technique with digital Dolby Digital and large top quality speakers then install OFC speaker cables and you are going to be stunned.
