Coaxial speaker cable are widely used these days due to the great quality of sound they produce and the simplicity they provide. These cables always guarantee correct digital audio signal transmission.

A male RCA connector is often found on both ends of a coaxial speaker line. They are immune to interference and are capable of delivering lossless audio output.

Furthermore, they may power a variety of equipment such as cable/satellite boxes, DVRs, HDTVs, Blu-Ray/DVD players, subwoofer speakers, game consoles, and so more.

In this overview of coaxial speaker cables, we will go through coaxial cables in depth. We’ll look at the physical and electrical properties of a standard coaxial cable.

Following that, we will look at several sorts of coaxial cables.

In terms of sound, we will examine the advantages and disadvantages of utilizing a coaxial speaker cable rather than HDMI or Optical Cables enabling digital audio transmission.

What Is Coaxial Speaker Cable?

The name “coaxial” refers to the cable’s structure. The cable’s core is coated with an interwoven layer of copper, and the core and coating are aligned on the same axis, thus the name.

Coaxial speaker cables use RF signals to carry audio signals from an input source (a computer or another audio output) to an output source (the speakers).

These cables produce clear sound at the speaker’s end. The audio signals they convey encompass the full audible audio range as well as the lower end of the infrared spectrum, ranging from 20KHz to 300 GHz.

What Are The Uses Of Coaxial Speaker Cable?

People use this cable for high-speed data buses and telephone transmission, as well as networking cables, cable television hookups, and numerous receivers.

Coaxial cables are utilized in radio communication systems, telecommunication systems, and wireless systems.

We use them for TV antennas, HD TV, cable TV, cable internet, audio and video transmission, and other similar purposes.

For various purposes, several cable types and connections are employed. For radio applications, 50 coax cables (such as RG-8 and RG-58) are utilized.

The most common cable types such as RG-6, RG-7, RG-11, and RG-60 along with connector types such as the F-type connector are used for cable TV, high-speed cable internet, and satellite TV.

Types Of Coaxial Speaker Cable

Coaxial speaker cables are classified according to their input impedance, structure, and RG Standards.

Based On Impedance

50Ξ© Coaxial Speaker Cables


These reduced impedance cables are primarily used for radio communications.

75𝛀 Coaxial Speaker Cables


The 75𝛀 cable is a well-known and widely used coaxial cable.

The cable you use for cable TV is usually a 75𝛀  coaxial cable.

In addition to cable TV, the 75𝛀  coaxial cable is employed in RF video and audio transport.

Based On Design & Properties

Flexible Coaxial Cable


It is a typical form of coax with a braided exterior conductor constructed of fine wires.

The cable becomes more flexible with this braiding, but it lacks full insulation.

As a result, signals can leak through the microscopic pores in its braid.

Semirigid Coaxial Cable


If shielding and limiting signal leakage are more important to you than flexibility, the semirigid coaxial cable is an excellent alternative.

As the name implies, this form of coaxial cable is stiff and sturdy, comparable to pipes.

An outer metallic coating serves as a secondary conductor. Furthermore, the metal layers aid in keeping a consistent impedance along the length of the cable.

However, due to the cable’s rigid structure, it will not be very flexible.

Dual Coaxial Cable


Two distinct coax wires are encased in a common exterior insulating jacket in this model.

As a result, this kind can manage quicker data transfer with increased bandwidth.

Twinaxial Cable


Each dual axial cable contains coupled insulated conductors encased in a shared exterior conductor.

These conductors in the middle must be parallel to each other or curved.

People commonly use this type in multiple high-speed data transfers for massive computer systems.

Triaxial Cable


Triaxial cable, often known as Triax cable, has two exterior conductors divided by a dielectric layer.

An outbound conductor functions as a signal ground, while the other functions as an earth ground.

As a result, this kind provides higher signal strength and shielding.

Based On RG Standard

RG (Radio Guide) is another form of coax cable. Although the RG standard code is no longer in use, the wires are still commonly utilized.

This code will tell you the diameter of the wire, its out diameter, dielectric type, impedance, and shielding.

Based on the code, you will know what sort of connection will work best with each RG cable type. RG coax cables are classified as RG-6/U, RG-6/UQ, RG-8/U, RG-8/X, RG-11/U, RG-58/U, RG-59/U, and RG-60/U.

Types Of Connectors

The most popular connectors for coax cables are BNCs, SMAs, MCXs, 7/16 DINs, QMAs, N-Types, SMBs, TNCs, RCAs, and F-types.



The F-Type Connector is a common type of Coaxial Cable Connector.

If you have cable TV, you most likely utilize this style of connector to connect the cable to your set-top box or receiver.

In the cable television industry, the combination of RG-6 Coaxial Cable with an F-Type Connector is fairly prevalent. As a result, they are widely available and reasonably priced.

In terms of results, Coaxial Cables with F-Type Connectors can typically withstand frequencies up to 1 GHz. F-Type Connectors are available in 50 and 75 impedances.



It is among the first Microwave RF Connectors that can operate at frequencies up to 11 GHz, with some variants capable of reaching up to 18 GHz.

We use N-Type connections in a variety of low-frequency microwave applications due to their tough and weather-proof construction.

Spectrum analyzers, antennas, and other devices employ N-Type connections with coaxial cables as input.

SMA Connector


SMAs are mostly used in RF applications. However, they were initially designed for frequencies spanning from 0 to 12 Hz.

Modern SMAs may operate at frequencies of up to 24 GHz.

They design SMAs for mobile phone transmitters, handheld transmitters, wifi transmitters, and microwave devices.

SMB Connector


The SMB Connector is a suitable alternative if you need a much smaller connector than the SMA Connector.

BNC Connector


BNC connections are an abbreviation for Bayonet Neil-Concelman connectors.

You can find these cables in RF and video applications such as televisions, testing tools, radio frequency equipment, and radios.

Aside from its ease, our resident audiophiles love this coax cable connection for its stable wide-range frequencies ranging from 10 GHz to 4GHz.

Anything beyond that, on the other hand, may result in radiation and loss.

TNC Connector


Threaded Neil-Concelman (TNC) choices are similar to BNC but exist in a threaded variant.

When working with microwave frequencies, however, our staff would prefer TNC connections over BNC.

Unlike other coaxial cable connections, it only exists in a 50-Ohm configuration, yet it can withstand activities up to 11GHz.

These high frequencies are mostly due to its screw connection and quality threaded construction, which BNC lacks.

RCA Connector


RCA connections are another popular choice to explore.

These cables can tolerate frequencies up to 10 MHz.

Although RCA is the industry’s oldest form of connection, it is still widely available.

If you plan to utilize the coaxial wire for home theater systems, RCA connections in a mounted subwoofer will suffice.

MCX Connector


Connector-required equipment is different for individual cases. So, in case of one that can accommodate applications with restricted size or space, tiny coaxial connections might come in handy.

It works well with antennas and PCBs. This connector’s electrical capability can handle up to 6GHz.

We can find these coax cable connectors in telecommunications, wireless connectivity, and GPS applications.

It’s also available in 50-Ohm and 70-Ohm versions.

QMA Connector


The QMA Connector is a quick-connecting alternative to the SMA Connector.

QMA connectors can tolerate frequencies up to 6 GHz.

They use the QMA Connector in mobile phone base station antennas, defense, and military RF communication systems.

7/16 DIN Connector


The 7/16 DIN Connector is another threaded RF Connector. This connector is used in cell phone antenna networks for high-power RF connections.

The axis of all these distinct cylindrical layers is the same if you take a cross-section of them.

How To Use Coaxial Cables For Speakers & Subwoofers

A coaxial speaker cable is a long-lasting choice for transmitting professional-level audio signals from an amplifier or receiver to speakers.

To connect to an externally powered subwoofer, many audio systems employ RCA coaxial wires. You’re already aware of the technique of assembling coaxial speaker cables if you know how to attach your own connectors to a speaker wire.

You may accomplish it by hand by cutting the connections, removing the shielding, and wrapping the braiding into a single thread between the two.

When connecting a subwoofer to an audio receiver across long distances, a coaxial cable for a subwoofer can be used.

All television cables, including digital coaxial cables, have a standard impedance of 75 ohms.

As a result, they are completely interchangeable. Other cables with RCA connections meant for audio transmissions, such as the subwoofer cable, may not have a 75-ohm impedance.

Another alternative is to use the Phat Satellite coax cable, which is 100 feet in length.

It is capable of overcoming link resistance and working effectively with bigger speakers and subwoofers.

Advantages of Using Coaxial Cables

Coax cables are less susceptible to noise and interference than standard twisted pair connections.

Generally, users have a lot of fun working with different types of coaxial cables over short distances since they provide consistent performance and better sound quality than standard speaker wire.

While the shorter length may be an issue, the thicker conductor and lower induction rate make up for it. The cheaper cost of coax cables is the icing on the cake. 

This connection is ideal for audiophiles on a tight budget since it is relatively inexpensive without losing visual or audio quality.

Disadvantages of Using Coaxial Cables

The use of this type of audio signal transfer may generate unpleasant electrical noise.

Because it’s only one cable, if there’s a flaw, everything stops operating, therefore maintain the cable intact.

While these cables are recognized for significantly improving audio connection quality, coaxial configurations do not enable popular sound systems like DTS-HD Master Audio.

If you use it frequently and extensively, you may notice that its speed fluctuates from time to time.

Last Words

Coaxial speaker cable deliver professional-quality sound through an extremely robust connection. If you’re having significant signal noise or interference, coaxial speaker cables may be the solution.
