Why People Use Coaxial Speaker Cable – A Complete Guide

These days, Coaxial Speaker Cable are relatively widespread and may be found in every home. They can be used as Coaxial Speaker Cables, TV antennas, modems, cable boxes, and for the transmission of audio and video signals. You’ve come to the correct site if you’re looking to learn more about coax cables.

This article will discuss several coaxial cable kinds, examine the physical and electrical properties of coaxial Speaker cables, and provide a list of possible applications. We’ll also discuss the possibility of employing coaxial speaker wires and weigh their advantages and disadvantages.

How Does It Appear?

Simple cylindrical shapes characterise coaxial wires. Every Coaxial Speaker Cable comprises four essential components, regardless of its thickness, colour, or complexity of structure. These four factors are:

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

The core is often made of copper. The usage of stranded copper and copper-plated steel is also typical. A dielectric insulator encircles the core conductor. The material for this insulator can be solid plastic, foam plastic, or air with spacers. Copper braided wire is typically used as the shield. Sometimes the braid is silver-plated.

Cables of higher grade could have two shields, one made of braided copper wire and the other of aluminium foil. Two layers of aluminium foil and two layers of braided copper wire can sometimes be used as four layers of shielding. Although enhanced shielding reduces losses and boosts performance, it also thickens and makes the cable less flexible, which is not always preferred.

The topmost layer of the jacket is often made of PVC (Polyvinyl Chloride). The jacket may also be built of a material that is water-resistant, oxidation- and ultraviolet-light-resistant, or fire-resistant, depending on its intended use.


  • Affordable
  • Simple to set up and grow
  • Durable
  • Its resistance to EMI and RFI enables high-frequency applications
  • Broadband transmission
  • High rates of transfer


  • The network is brought to a halt by a single cable failure
  • It must be grounded
  • It could be rigid and thick, which makes installation considerably more difficult

Which Connector Types Are Used with Coaxial Speaker Cable?

Different connections are needed for various cable types and purposes. Although various connections can be used with coax cables, the BNC, N-type, SMA, F-type, and RCA connectors are the most widely used.

BNC connectors

Applications involving RF and video employ BNC connectors. It was built to work with frequencies up to 10 GHz (stable up to 4 GHz – after that, it may radiate signal, and the losses increase).

N-type connectors

N-type connectors are made for use up to 18 GHz at lower microwave frequencies. It is employed in some RF applications (communications and broadcast equipment).

SMA connectors

For RF applications, SMA connections are frequently used connectors. The SMA connector was initially intended to function with frequencies between 0 Hz and 12 GHz. SMA connectors available today can handle frequencies of up to 24 GHz. Handheld radio antennas, mobile phone antennas, microwave systems, wi-fi antennas, etc., all employ SMA connectors.

F-type connectors

Due to their use in TV cables and antenna cables, F-type connectors are by far the most prevalent connector type for coaxial cables. Frequencies up to 1 GHz can be handled using F-type connectors.

RCA connectors

Coaxial Speaker Cable are frequently used with RCA connectors as well, typically for the transmission of audio and video. They are capable of operating at up to 10 MHz.

What Is the Purpose of Coaxial Speaker Cable?

Wi-fi, telecommunication, and radio communication systems all employ coaxial cables for various purposes. They are used for various things, including audio and video transmission, HD TV, cable TV, and the internet. For various applications, different cable types and connectors are employed.

Cable TV, high-speed cable internet, and satellite TV use the most popular cable types (such as RG-6, RG-7, RG-11, and RG-60) and connector types (F-type connectors). Fifty coax cables (such as RG-8 and RG-58) are utilised for radio applications.

Coaxial Digital Audio Cable: What Is It?

Transmission of audio signals is one of the common uses for coax cables. We employ the so-called coaxial digital audio wire for audio transmission. It has RCA connections and is the same standard 75-ohm coax cable that we previously discussed (it might also be AWG 18 like RG-6).

Although they are made to convey a digital signal, they have the same visual appearance as analogue RCA cables. Another distinction is that only one coax audio cable is required to send the whole signal. You need two analogue RCA cables (left and right).

Additionally, analogue RCA cables typically have a 50 impedance, whereas digital coax cables have a 75 impedance. Uncompressed 2ch PCM audio, DTS and Dolby Digital up to 5.1, and other audio formats are supported over coaxial audio cable.

Coaxial speaker cable: Is it Priceless?

So, is it worthwhile to utilise coax cable as speaker wire even though you can? Will a coaxial speaker cable rather than a standard speaker wire result in any auditory improvements? In our opinion, there isn’t much of a justifiable difference between the two to warrant the price difference and the effort. Thus, we don’t believe it is worthwhile.

But not everyone concurs with this assertion. Some said that switching from standard 14-gauge speaker wires to Mogami cables improved their stereo systems noticeably. Try them out and see whether they work for you; that’s the best tip we can give you. They aren’t outrageously costly, after all (15 feet of WBC coax speaker cable utilising Mogami coax speaker wire is about $115).

Can I Make My Own Coaxial Speaker Cable?

Numerous DIY instructions may be found online for creating coaxial speaker cables. Some are pretty simple to follow and extremely thorough. Others are brief and unclear. The lesson on creating John Risch’s cross-connected coax speaker wire was the most straightforward explanation we’ve found. As you are already aware, we don’t believe the effort involved in creating this unusual cable is worthwhile, but you are welcome to give it a shot and see if you enjoy the results.
