Coaxial Speaker cables power various appliances like cable/satellite boxes, game consoles, Blu-Ray/DVD players, HDTVs, DVRs, subwoofer speakers, and many more.

It’s hard to decide the best coaxial cable for you, but luckily that’s where I can help. Based on my research, I have build a list of coaxial cables.

This guide will give you an in-depth analysis of coaxial speaker cables. I will discuss the types, components, materials, pros and cons, usage, and more. Let’s read on to discover!

What is Coaxial Speaker Cable?


The term ‘coaxial’ denotes the construction of the cable. The core (inner conductor) and the copper shielding (copper wires woven around the core) are co-axial.

The cable was first invented in 1858. And, it got patent in 1880. Coaxial cables have been a staple of every home. In addition to televisions, it has been a standard cable since the beginning of the 20th century.

An RF signal transmits through these cables, connecting a destination device to an input device.  

These cables send low infrared frequency waves to higher-end audible frequencies, which range from 300GHz to 20kHz. 

In other words, a coaxial speaker cable is an electrical wire that transmits radio signals from a source to a destination. These cables are becoming popular in professional home audio setups. They deliver consistent sound quality. 

They are identical to RCA audio cables aside from the fact that they transmit digital signals. A reliable connection establishes due to the higher bandwidth offered by these cables. 

Some coaxial speaker cables are used with subwoofers only. These cables can be used with subwoofers and loudspeakers up to 75 cm or 6 meters long. They offer secure connections and high-quality sound due to their construction. 

Mic cables comprises of three-pin XLR connectors. XLR cables are popular microphone cables because they have a low signal-to-noise ratio. 

XLR cables transmit signals from source devices to destination devices (20 kHz to 300 GHz). These cables are widespread, and most speakers now use them. They are popular because they deliver high-quality audio without noise.

What Is a Digital Coaxial Cable?


Digital coaxial cables can transmit any electrical or digital signal. These cables transfer video and audio signals. Although digital signals are transmitted across them via electrical pulses, they are not digital internally. 

The structure of digital coaxial cables is the same as that of regular coaxial cables. A metal shield covers a wire at the center, surrounded by insulation-like material, and a plastic sheath. 

In addition, they are resistant to interference and have a high impedance to electrical currents. Because they can handle a wide range of electrical frequencies, digital coaxial cables are particularly suitable for high-end applications. 

What Does It Look Like?


The coaxial cable is cylindrical. Its thickness and colour vary, and its shape might be complex. Every coaxial cable has 4 key elements. Here are they:

  • Core conductor 
  • Dielectric insulator 
  • Metallic shield 
  • Plastic jacket 

The core conductor is usually copper-plated steel or stranded copper. A dielectric insulator is positioned around the core. It is generally made of solid plastic, foam plastic, or air with spacers. 

Braided copper wires are used for the shield. Although some high-quality cables employ a silver-plated braid. Because shielding is vital to preventing losses. Shielding is enhanced with two layers of aluminium foil and two layers of braided copper wire. 

Pros and Cons of Coaxial Speaker Cable

Coaxial speaker cables are widely used in radio communications, telecommunications, wi-fi systems, cable TV, and cable modems.

Coaxial cables are specially designed and built to provide many advantages. They are less susceptible to electromagnetic and radio-frequency interference due to their excellent shielding and outer jacketing. 

Additionally, coax cables are suitable for high-frequency applications (50 MHz and higher). Furthermore, coaxial cables are cheaper, simpler to install and expand, and more durable than twisted-pair cables. 

Coaxial cable, while inexpensive, simple to install, and long-lasting, also has some drawbacks. A network’s failure/breakdown is likely if a single cable carries all network traffic.

  • It lasts for a long time
  • Lower signal loss
  • Excellent professional sound quality
  • Outstanding performance in short-distance transmission
  • Suitable for wide bandwidth signal transmission
  • Reduced sensitivity to interference or noise (RFI or EMI)
  • High tensile strength to work nicely in different environments
  • Installation is easy and expands due to flexibility
  • Available at a lower price
  • Huge construction
  • Loss of some signal across long-distance transmission
  • Signal leakage occurs at the connection
  • Fluctuation of speed during heavy use
  • Costly installation for longer distances
  • It takes time to run
  • Higher capacitance results in instability, while using long cables

Can Coaxial Cable Be Used for Subwoofer?

Use a coaxial cable if a subwoofer needs to be linked to a receiver over a long distance.

Coaxial cables and video cables, have an impedance of 75 ohms. Because they are fully compatible, digital coaxial cables are available. 

Some other cables which use RCA connectors to transmit audio, including a subwoofer cable, may not have a 75 ohms resistance.

What Are Different Types of Coaxial Cables on the Market?


Coaxial cables are categorised by thickness, material, function, connector design, and current resistance. They are frequently sorted based on Impedance, with 75Ω and 50Ω impedance coaxial cables being the most popular. 

There’s a range of impedance ratings available aside from these two values. 75Ω coaxial cable is typically used for RF transmissions in homes, although 50Ω is also used. 

Here’s a list of different types of coaxial cables on the market:

According to Construction

  1. Flexible coaxial cable – They have a braided outer conductor that makes them easy to work. These cables have the least amount of protection.
  1. Semi-rigid coaxial cable – This is a rather sturdy cable with an exterior conductor made of metal. These are less elastic than flexible cables but have more substantial shielding.
  1. Triaxial Coaxial cable – A dielectric sheet on these cables separates two external conductors. One of the conductors acts as an earth ground, whereas the other is a signal foundation. Noise resistance and insulation are improved when these elements work together.
  1. Dual Coaxial cable – Two cables covered by a single exterior jacket
  1. Twinaxial cable – Consists of two insulators with the same exterior conductor, which are excellent for high-speed signal transfers.

On the Basis of Impedance

  1. 50 Ohms Impedance – 50-Ohm cables are frequently used for radio communications. It has 50 Ohm’s compatibility with various antenna types and radio transmitters. These cables are also utilised for high-speed digital communications and coaxial Ethernet networks.
  1. 75 Ohms Impedance – 75-Ohm cables are generally found in houses. They are used for audio/video transmission and telecommunications, RF video transmission and cable TV systems. 

According to Radio Guide (RG) Standard

Radio Guide or RG standard is used for the classification of coaxial cables. Cable types are called by the letters R and G, followed by a number and another. The RG standard describes the following about coaxial cables:

  • Outer diameter
  • Core wire diameter
  • Impedance
  • Shielding
  • Dielectric type and diameter

Types of Connectors Used for Coaxial Cables?

Coaxial cable connectors maintain proper shielding on connecting cables by utilising unique connectors. You will find superior connectors are reliable and durable for connecting cables to other devices. The following are different types of connectors for coaxial cables:



BNC stands for Bayonet Neil-Concelman. They are used for connecting/disconnecting TVs, radios, RF equipment, test instruments, etc. These RF connectors are available in small to medium sizes. 



TNC stands for Threaded Neil-Concelman. These connectors indicate threaded versions of a BNC connector. They work at better microwave frequencies than BNC connectors.



SMB stands for Subminiature version B. These connectors are concise versions of SMA connectors. They deliver excellent electrical performance from DC to 4 GHz.



In terms of internal construction, QMA connectors are similar to SMB connectors. But, QMA connectors provide faster locking and disconnection convenience.

7/16 DIN


7/16 DIN stands for Deutsches Institut für Normung connectors. These are threaded RF connectors used for signal transmission that needs high wattage. In addition, they are used in defense applications, cellular networks, and antenna systems combined with multiple transmitters.



RCA stands for Radio Corporation of America. These connectors are known as cinch connectors. They work with red, white, and yellow cables that plug into the rear of TVs.



MCX stands for Micro coaxial connectors. They come in small forms factors. In addition, they are ideal for applications with limited size, space, or weight.

FAQs about Coaxial Speaker Cable

1. Coaxial, Optical, or HDMI – Which is the Best for Audio?

Let’s discover how each of them is different:


Coaxial digital connections are utilised for audio transmission. The circular-shaped RCA connector is used as a connector. Compared to optical connections, coaxial connections sound better because they offer a wider bandwidth than optical connections.

The electrical signal travels through a coaxial connection up to 192 kHz, whereas the optical connection is limited to 96 kHz. 

On the other hand, a coaxial connection supports superior audio up to 192 kHz, whereas the optical connection usually supports only 96 kHz. In addition, electrical noise produce in your equipment when using a coaxial digital connection.


Optical fibers transmit data via light in optical digital connections. Unlike coaxial digital connections, optical connections do not allow noise to pass from a source to DAC circuitry. Glass, silica, and plastic can help in making these cables. 

Because optical connections can restrict noise, they might utilise in connecting to the DAC of an AV receiver or soundbar. Additionally, an optical digital connection supports up to two channels of uncompressed PCM audio. 


HDMI connections have far better bandwidth than coaxial or optical digital links. Therefore, audiovisual receivers, sound bars, Blu-ray players, and TVs connects through HDMI interfaces. 

You will see HDMI inputs and outputs as firm fixtures on AV receivers, soundbars, Blu-ray players, and TVs. It allows for smooth playback of lossless audio formats like DTS-HD Master Audio and Dolby TrueHD. Concerning the newest and existing video formats, HDMI supports them both.

Both digital optical and coaxial digital audio cables are identical in one respect. They may send an audio signal from a DVD player to an A/V receiver or digital recording device via a fibre optic cable or a coaxial digital speaker cable. 

The digital optical connection sends a digital audio bitstream using light pulses. In contrast to the standard RCA cable, a digital coaxial cable differs substantially due to its capability to support a wider frequency bandwidth for the digital audio bitstream. 

3. How Do I Connect Speaker Wire to Coaxial Cable?

Follow the below steps to connect a speaker wire to a coaxial cable:

  • Take a sharp utility knife to cut any existing connectors.
  • Measure how much wire length you require, and then cut the cable accordingly.
  • Cut off 1.5 inches of external insulation from both ends of the cable.
  • Unbraid the speaker wire shielding, which is present around the core wire on both ends.
  • Wind the braiding into a firm single thread of wire.
  • Take off the semi-transparent insulation around the core wire on either end using a wire stripper.
  • Finally, connect the uncovered core wire to the red connector over the speaker and rear of the audio receiver. Now connect the braided strand to the end of the receiver and black connector over the speaker.

4. Is Coaxial the Same as RCA?

Coaxial audio cables and RCA cables are of similar size and shape. They both have a 75-ohm impedance and bandwidths identical to each other. Coaxial cables are thicker than RCA cables. They both have the same shielding to prevent interference. Coaxial cables can transport digital signals, whereas RCA cables cannot. 

5. Is Coaxial Speaker Cable Worth It?

Is it worth spending more for a coaxial audio cable over an ordinary speaker wire? Using a coaxial audio cable for your speaker system will give you a few minor advantages, but the higher price tag is not worth those advantages. 

Even if you think the subtle distinctions are worth the price, most people will find little to justify the cost of coax cables over traditional speaker wires. Instead, they should stick with conventional wires.

6. Can I Make a Coaxial Speaker Cable on My Own?

There are several DIY coaxial speaker cable tutorials. Some are very straightforward to follow, while others are brief and confusing. The tutorial on making John Risch’s cross-connected coax speaker cable is the best I’ve seen. 

As you already know, I don’t think creating this intricate cable is worth all the trouble, but you can try it and see if you like it. 



In conclusion, a Coaxial speaker cable is excellent for digital audio transmission because it maintains signal integrity while delivering superior audio. 

Moreover, they work well with the most advanced audio and visual equipment. This cable is ideal for a wide range of audio-visual equipment. You do not lose data with superior audio quality and no signal interference.
