These days, coaxial speaker cables are widely used because of the excellent sound they produce and how easy they are to use. These cables always ensure that digital audio signals are transmitted correctly. On both ends of a coaxial speaker line, a male RCA connector is frequently present. They are able to deliver lossless audio output and are immune to interference.
Additionally, they could supply power to a wide range of devices, including game consoles, HDTVs, Blu-ray or DVD players, DVRs, cable or satellite boxes, and so forth. We will go over coaxial cables in detail in this overview of coaxial speaker cables.
We’ll examine a standard coaxial cable’s physical and electrical characteristics. After that, we’ll examine various coaxial cable types. We’ll look at the benefits and drawbacks of using coaxial speaker cables for digital audio transmission rather than HDMI or optical cables in terms of sound.
What Is Coaxial Speaker Cable?
The term “coaxial” refers to the design of the cable. The name comes from the fact that the core and coating of the cable are aligned on the same axis and are coated with an interwoven layer of copper.
From an input source (a computer or another audio output) to an output source, coaxial speaker cables use RF signals to transmit audio signals (to the speakers).
At the speaker end, these cables deliver crystal-clear sound. The audio signals they transmit span the entire audible audio spectrum and the lower infrared spectrum, from 20 kHz to 300 GHz.
What Are The Uses Of Coaxial Speaker Cable?
This cable is used for high-speed data buses, telephone transmission, networking cables, cable television hookups, and a variety of receivers. Radio communication systems, telecommunication systems, and wireless systems all use coaxial cables.
We use them for TV antennas, HD TV, cable TV, cable internet, audio and video transmission, and a variety of other applications. These Various cable types and connections are used for various purposes. 50-ohm coax cables (such as RG-8 and RG-58) are used for radio applications.
Cable TV, high-speed cable internet, and satellite TV use the most common cable types, such as RG-6, RG-7, RG-11, and RG-60, as well as connector types such as the F-type connector.
Types of coaxial speaker cable
The input impedance, structure, and RG standards of coaxial speaker cables are used to classify them.
Based on impedance
50 coaxial speaker cables
Radio communications are the primary application for these low impedance cables.
75 coaxial speaker cables
The 75 cable is a common and well-known coaxial cable. Cable TV is often delivered through a 75-foot coaxial cable. The 75 coaxial cable is used in RF video and audio transfer, in addition to cable TV.
Based on Design and Properties
Flexible coaxial cable
It is a common type of coax with a braided outer conductor made of fine wires. This braiding makes the cable more flexible, but it lacks full insulation. As a result, signals can seep through the braid’s small holes.
Semirigid coaxial cable
If shielding and signal leakage are more essential to you than flexibility, semirigid coaxial cable is a great option. This type of coaxial wire is stiff and strong, similar to pipes, as the name implies.
A secondary conductor is provided via an exterior metallic covering. Furthermore, the metal layers contribute to maintaining a constant impedance along the length of the cable.
However, due to the hard structure of the cable, it will not be extremely flexible.
Dual Coaxial Cable
Two different coax cables are enclosed in a common outer insulating jacket in this variant. As a result, this type can handle faster data transfers with greater bandwidth.
Twinaxial Cable
Coupled insulated conductors are wrapped in a shared external conductor in each dual axial cable. These conductors in the center must be either parallel or bent.
This kind is widely used for multiple high-speed data transfers for large computer systems.
Triaxial Cable
Triaxial cable, often known as “Triax cable,” is made up of two external conductors separated by a dielectric layer. One conductor serves as a signal ground, while the other serves as an earth ground. As a result, this type offers greater signal strength and shielding.
Based on the RG Standard
Another type of coax cable is RG (Radio Guide). Despite the fact that the RG standard code is no longer in use, the wires are still widely used.
This code indicates the wire’s diameter, outer diameter, dielectric type, impedance, and shielding.
The code will tell you what style of connection will work best with each RG-6 cable type. There are six types of RG-59 coax cables: 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
BNCs, SMAs, MCXs, 7/16 DINs, QMAs, N-Types, SMBs, TNCs, RCAs, and F-types are the most commonly used connectors for coax cables.
F-type
A typical type of coaxial cable connector is the F-Type Connector.
If you have cable TV, you most likely connect the cable to your set-top box or receiver using this type of connector. The combination of RG-6 coaxial cable and an F-Type connection is fairly common in the cable television industry.
As a result, they are widely available and inexpensive. Coaxial cables with F-Type connections can normally sustain frequencies of up to 1 GHz. F-Type connections are offered in impedances of 50 and 75.
N-type
It is one of the earliest microwave RF connections capable of operating at frequencies up to 11 GHz, with some variations reaching up to 18 GHz.
Because of their strong and weather-proof structure, N-Type connections are used in a range of low-frequency microwave applications.
N-type connections with coaxial cables are used as input by spectrum analyzers, antennas, and other devices.
SMA Connector
SMAs are typically employed in radio frequency (RF) applications. They were, however, originally designed for frequencies ranging from 0 to 12 Hz.
SMAs can now operate at frequencies of up to 24 GHz. SMAs are used in mobile phone transmitters, portable transmitters, WiFi transmitters, and microwave equipment.
SMB Connector
If you require a significantly smaller connector than the SMA connector, the SMB connector is a viable option.
BNC Connector
Bayonet Neil-Concelman connectors are abbreviated as BNC connections. These cables can be found in RF and video applications such as televisions, testing tools, radio frequency equipment, and radios.
Aside from its convenience, our resident audiophiles appreciate this coax cable connection’s steady, wide-range frequencies of 10 GHz to 4 GHz. Anything above that, however, may result in radiation and hearing loss.
TNC Connector
Threaded Neil-Concelman (TNC) options are identical to BNC but are threaded. However, when working with microwave frequencies, our crew prefers TNC connectors over BNC.
It only exists in a 50-Ohm configuration, unlike other coaxial cable connections; however, it can resist activity up to 11 GHz.
These high frequencies are mostly due to its screw connection and quality threaded construction, which BNC does not have.
RCA Connector
Another popular option to investigate is RCA connectors. These cables can withstand frequencies as high as 10 MHz.
Although RCA is the industry’s oldest connection method, it is still commonly used. If you intend to use coaxial wire in your home entertainment system, RCA connections in a subwoofer will suffice.
MCX Connector
Individual scenarios necessitate various connector-required equipment. Tiny coaxial connections may come in handy in the event of one that may handle applications with limited size or area.
It is effective with antennas and PCBs. The electrical capability of this connector is up to 6 GHz.
These coax cable connectors can be found in telecommunications, wireless connectivity, and GPS applications. There are also 50-Ohm and 70-Ohm versions available.
QMA Connector
The QMA Connector is a fast-connecting replacement for the SMA Connector.
QMA connectors can withstand frequencies as high as 6 GHz.
The QMA Connector is used in mobile phone base station antennas as well as defense and military RF communication systems.
7/16 DIN Connector
Another threaded RF connector is the 7/16 DIN connector. This connector is used for high-power RF connections in cell phone antenna networks.
A cross-section of all these separate cylindrical layers reveals the same axis.

How to Use Coaxial Cable for Speakers and Subwoofers
A coaxial speaker cable is a durable option for delivering high-quality audio signals from an amplifier or receiver to speakers. Many audio systems use RCA coaxial wires to connect to an externally powered subwoofer.
If you know how to connect your own connectors to a speaker wire, you’re already familiar with the procedure for manufacturing coaxial speaker cables.
By severing the connections, removing the shielding, and wrapping the braiding into a single thread between the two, you can do it by hand. A coaxial cable for a subwoofer can be used to connect a subwoofer to an audio receiver over long distances.
The standard impedance of all television cables, including digital coaxial lines, is 75 ohms. As a result, they can be used interchangeably. Other audio cables with RCA connections, such as the subwoofer cable, may not have a 75-ohm impedance.
Cimple Co. Cable
This cable is 25 feet long and very affordable. If you wish to convert your coax wire into a speaker cable, you’ll need at least this length to keep your system from blowing up.
As a result, if you need a longer cable, the Cimple Coax Cable is a good choice.
Phat Satellite Cable
Another option is to use the Phat Satellite coaxial cable, which has a length of 100 feet. It has the ability to overcome link resistance and function successfully with larger speakers and subwoofers.
Advantages of Using Coaxial Cable
Coaxial speaker cables are less prone to noise and interference than twisted pair connections.
Users enjoy dealing with various types of coaxial cables over short distances because they give consistent performance and higher sound quality than ordinary speaker wire.
The shorter length may be a disadvantage, but the thicker conductor and lower induction rate compensate. The lower cost of coax cables is the cherry on top.
This connection is great for audiophiles on a restricted budget because it is reasonably priced without sacrificing visual or aural quality.
Disadvantages of Using Coaxial Speaker Cable
The use of this method of audio signal transport may result in undesirable electrical noise.
Because there is just one cable, any flaw causes everything to cease working; thus, keep the cable intact.
While these cables are known for considerably increasing audio connection quality, they do not support popular sound systems like DTS-HD Master Audio.
You may notice that its speed fluctuates from time to time if you use it regularly and intensively.
Conclusion
Coaxial speaker cable provides professional-quality sound through a strong connection. Coaxial speaker cables may be the answer if you’re experiencing substantial signal noise or interference.
