What is the difference between Speaker Wire and Audio Cable?

Speaker Wire is mainly used to connect power amplifiers and main speakers and surround speakers in home theaters, that is, to connect power

 amplifiers and speakers. Compared with video cable and Audio Cable, its current signal is relatively large. Due to the large signal amplitude, 

Speaker Wire often has no shielding layer.

For this kind of wire, the key is to reduce its resistance, because the output resistance of modern power amplifiers is very low, so the requirements

 for the Speaker Wire will also increase, such as the use of large cross-sectional area or multi-stranded wire. What is the difference between 

Speaker Wire and Audio Cable?

 

1. The difference between wires

Speaker Wire passes the power signal directly. Because the current is large, the copper core of the wire is usually thick. In order to ensure high 

frequency passage and reduce resistance attenuation, most of them are silver-plated, gold-plated or oxygen-free copper wires. Speaker Wire is 

generally divided into copper-plated Speaker Wire and oxygen-free copper Speaker Wire.

Generally, oxygen-free copper is the positive electrode, and tin-plated copper is the negative electrode. The color of the double skin is red, both

 sides are brass-colored, and the oxygen-free copper core is marked with a red line on the positive side. Speaker Wire is composed of the 

corresponding number of copper cores. Generally, the more copper cores, the better the effect and the higher the price. However, if it is a 

household wire or ordinary speaker wire, 200 to 300 is actually enough. Up.

 

Audio Cable is a wire used to transmit electro-acoustic signals or data. It passes signals with low current and low power. It has high impedance 

and is easy to be interfered. Therefore, it is generally a shielded wire, and the wire diameter is generally relatively thin.

 

 

2. The difference between Speaker Wire and Audio Cable

 

Speaker Wire mainly transmits power signals, so Speaker Wire is required to have excellent electrical conductivity and high-quality transmission capabilities. 

At present, the oxygen-free copper speaker wire, also known as gold and silver wire, is more mainstream and has a lower resistance. Gold and silver

Speaker Wire usually has no shielding layer, because the current signal flowing in it is larger than the Audio Cable, and the signal amplitude is very large. 

The most important thing is to reduce the resistance of the line. The impedance of the power amplifier is very low when it is output.

 

Audio Cable passes low-power and small-current signals, and has high impedance, which is easy to be interfered. Therefore, it is generally a shielded wire and 

the wire is relatively thin. Audio Cable usually has a shielding layer, but Speaker Wire often does not have a shielding layer. The key is to reduce resistance. 

Connexions mainly promotes the oxygen-free copper Speaker Wire, which is mainly characterized by good electrical conductivity and low resistivity.

Audio Cable can be used to connect the cable between mobile phone, CD player, MP3 music output signal equipment and power amplifier. Speaker Cables are

 mainly used in various types of speakers, PA projects, home theater connections, and public space broadcasting systems.
