Beginner’s Guide on Coaxial Speaker Cable

In making a secure connection for video and audio signals, every home theatre power manager requires an option like a coaxial speaker cable. This cable is popular for providing the best sound quality. But did you know that xial speaker cable has different benefits also? Here at Techies Hubs, we will cover everything about axial speaker cable.

Coaxial Speaker Cable

What is a Coaxial Speaker Cable?

The person who wants to use a oaxial speaker cable must be aware of its standard definition and function before using it. This coax cable is usually used to transfer smooth RF signals from source to destination device.

The distinct speaker wire now can take upper-frequency spectrum to lower frequency spectrum from range 20 kHz to 300 GHz with a speaker coaxial. If you examine it closely you will find that the axial speaker cable has an internal metal conveyor and woven copper protection that shares one hub. This remarkable wire construction comes with the name coaxial.

In the 20th century for every home sound system, coaxial cables have become the necessary part. This cable is used in 1858 first time and gets patented in 1880. This coaxial cable is popular for delivering high bandwidth digital signals. It is also durable if compared with standard audio cables.

Components of axial speaker cable

Every cable coaxial have 4 main components to function properly. These four components are as follows:

  • Core conductor
  • Dielectric insulator
  • Metallic shield (usually woven copper)
  • Plastic jacket

It looks like a simple cable in cylinder shape during its first appearance. But it is unique as its tip is a core copper conductor covered with a dielectric insulator. For shielding, braided copper wire is used commonly. Sometimes it can be a silver-plated braid also. There have two shields for higher quality cables- aluminum foil merged with a braided copper wire. You can also find coaxial wire with four layers of shielding as well- two layers of braided copper wire and two layers of aluminum foil.

Merits and Demerits of Coaxial Speaker Cables

Coaxial cables are most widely used in wi-fi systems, radio communications, cable TV, telecommunications, and cable modems. There are some reasons why coaxial cable is so popular.

The construction and design of the digital coaxial cable are very nice. Outer jackets with greater shielding make coax cables less susceptible to RF and electromagnetic interference. It enables high-frequency applications like (50 MHz and higher). xial speaker cable have higher transfer rates and bandwidth transmission if compared with twisted pair cables. Coax cable is expandable and has easy installation and comes at an affordable cost. The only disadvantage of using this cable is that the entire network will be down if this cable breaks or fails.

Types of oaxial Speaker Cables

We can separate coax cables depending on their thickness, impedance, construction, on their dielectric type, and the connector they use. Depending on impedance you can separate it with 50Ω or 75 Ω impedance. 50Ω cable is generally used with radio transmission applications because 50Ω is best for radio Transmitters and high-frequency digital transmission.

Here is a list of speaker cabel and their uses:

Cable Type

Core diameter

Outer diameter







Cable TV, satellite TV, cable modems





Same as RG-8/U





HQ HD video signal transmission over short distances





Same as RG-6/U but with better shielding





Same as RG-7 but with lower losses





High-speed cable internet, HD cable TV





Amateur radio





Amateur radio, radio communications, Ethernet





Same as RG-6/U


Generally, 75Ω is best for household items. Mostly they are used in telecommunication for audio/video transmission. TV cable also uses the 75Ω coax cable. Some cables also came with 93Ω and 52Ω, but they are very less in use.

The connector used with Coaxial Speaker Cable

Different cables require different connectors and some of them are SMA connectors, BNC, RCA connectors, N-type connectors, and F-type connectors.


SMA connectors: RF applications generally uses SMA connectors. Mainly it works with 0 Hz to 12 GHz frequency range but in today's it can work with up to 24GHZ frequency.SMA connectors are mainly used in mobile telephone antennas, wi-fi antenna systems, hand-held radio antennas, microwave systems, etc.

BNC connectors: BNC connectors are used for video applications and radio frequency. It works up to 10GHZ (increase losses after 4GHZ).

RCA connector: RCA connector is also used for video and audio transmission and can manage up to 10 MHZ frequencies.

N-Type connector: N-Type connector is used up to 18GHZ frequency. They are used for radio frequency applications like broadcasting and communication equipment.

F-type connectors: F-type connectors are commonly used axial speaker cable connectors and are mainly used with antenna cables and TV cables. It can manage up to 1 GHz frequency.

Final Words:

In this article, we have tried to cover everything about xial speaker cables like their types, connectors they use, advantages, disadvantages, and how they work for audio and video. You can easily find oaxial speaker cable in the market these days.
