The speaker cable is used to connect the power amplifier and the speaker, and the current signal flowing in it is much larger than the aforementioned video cable and audio cable because of the large signal amplitude. This kind of wire often does not have a shielding layer. For this kind of wire, the key is to reduce its resistance, because the output impedance of modern power amplifiers is very low. Therefore, the requirements for speaker cables have also increased, such as the use of large cross-sectional area or multi-stranded wire.

What is the speaker wire harness
The wire used in audio equipment to connect between the power amplifier and the speakers. Since the speaker cable transmits a power signal, there should not be too much signal loss on it. This objectively requires the speaker wire to have extremely excellent electrical conductivity, and excellent electrical conductivity requires the wire to have extremely transmission capabilities. The main technical indicators currently used to measure these two points are the N value and the number of wire strands. The N value is a parameter that reflects the purity of the metal used in the production of the speaker wire. Generally, OFC oxygen-free copper and tinned copper +/- are easy to distinguish. Mainly used in various types of speakers, PA projects, home theater connections, public space broadcasting systems.

Sound wire function
Connect each part of the audio to transmit audio and video signals. This is the role of the audio cable. Many people think that the audio cable is just an accessory in the audio, there is no need to be so particular, just find a few pieces. Of course, this sound can also produce sound and picture, but in fact the effect has been compromised. Because whether it’s the audio signal transmission process from the disc player to the power amplifier to the speaker, Or from the disc player to a TV, projector to the transmission of the video signal, it has been subjected to poor transmission performance wire itself and external electromagnetic interference. These effects weaken and pollute these effects, so that the audio cannot emit high-fidelity sound. TVs and projectors cannot reproduce the realism. Therefore, friends who are using and going to use audio systems must know more about audio cables, make reasonable choices, and use them correctly, so as to ensure the best performance of audio.

The speaker cable is used to connect the power amplifier and the speaker, and the current signal flowing in it is much larger than the video cable and audio cable mentioned above. Because of the large signal amplitude, such lines often have no shielding layer. For this kind of wire, the key is to reduce its resistance. Because the output impedance of modern power amplifiers is very low, the requirements for speaker cables are increased, such as using large cross-sectional area or multi-stranded wire. The wires range from pure copper to silver wires, and one of the more expensive speaker cables is dedicated to oxygen-free copper speaker cables. Its main feature is good electrical conductivity and low resistivity. Use it to increase the timbre when replaying the sound. According to the classification of home speakers, it is divided into home theater speakers (usually 6) and HIFI music speakers (two), which are generally called fever boxes.

HIFI speakers are used to restore the recording sound field with high fidelity, so there must be sufficient protection for the lossless transmission of audio signals. Generally, transmission lines have different impedances to signals of different frequencies. This characteristic is manifested as poor sound quality in sound restoration. For this reason, people have produced a high-end speaker cable called smart signal cable, which is characterized by dividing the signal into two channels according to the frequency. A certain thickness of the outer line passes the signal above 5KHZ, and the signal below 5KHZ is transmitted through the inner layer of the line, which greatly improves the frequency characteristics of the transmission line and makes the replay sound effect good. But the price is also very expensive.

There are many kinds of wire rods on the market, and the prices vary greatly. Among them, the brand uses high-quality oxygen-free copper. Special attention is paid to the fact that there are many counterfeit wires in the market, so you must pay attention to it when purchasing. We can make the difference from the structure, material and appearance of the wire: Fever grade wires are made of high-purity ES-OCC (Oxygen Single Crystal Copper) or OFEC (Oxygen-Free Electrolytic Copper) to make conductor copper wires, which are flexible, tensile and flexural. The counterfeit wires are made of ordinary copper thin wires as conductor materials. In addition, the authenticity of the wire can be accurately judged from the appearance of the wire. Generally, the wires of authentic brands have trademarks, the typefaces of the models are printed very clearly, and it is difficult to rub off, the appearance of the craftsmanship is exquisite and standardized.
