How To Choose The Right Coaxial Speaker Cable For Your System

Mar 17, 2023 | 0 comments

In this article, we’ll examine the coaxial speaker cable, one of the best speaker connection alternatives now available, which has a history dating back to the 1850s. Numerous high-end applications where quality counts and technology are important have been introduced, replaced, or still utilise them. Let’s first examine how this technology functions before examining how coaxial speaker cables can provide great audio quality.

How to choose the right Coaxial Speaker Cable for Your System

If you want to get right down to it, a coaxial cable is just an insulated, shielded electric conducting cable. These cables transmit radio frequencies ranging from 20 kHz to 300 GHz in both analog and digital electric signal transmission.

These cables, which are frequently referred to as simply “coax,” are available in a wide range of types and connectors. Unknowingly, you have undoubtedly utilised a variety of coaxial cables. Coaxial cables are frequently referred to by the type of connection they use, such as “RCA” or “XLR.” The cable itself between the connectors is the “coaxial” component. In this instance, “RCA” is not the same as “XLR,” but both terms make use of a coaxial cable.

What purpose does a coaxical cable serve?

A transmitter and a receiver are physically connected by coaxial wires to transmit radio waves. Telecom businesses employed a coaxial cable to carry telegraphs over large distances, which is an example of a coaxial cable early adopter.

Technology such as HAM radio, video equipment, cable television, and audio systems allowed coaxial wires to enter the house. Coaxial cables were frequently used by TVs before HDMI to receive audio and video signals from equipment such as VCRs, DVD players, cable boxes, and gaming consoles using composite and component connections.

Your service provider uses a coaxial cable to transmit your cable TV and internet. The uses of coaxial cable that are exclusive to audio are numerous:

  • Stereos in homes (including connecting to speakers).
  • Recording audio with a microphone.
  • Connecting amplifiers to electric musical instruments.

How is a coaxial cable made?

Even though there are several varieties of coaxial cables with distinctive design modifications for certain functions, all coaxial cables contain the same four primary parts. These elements are, in order, from outside to inside:

A shield made of plastic

The exterior of the cable does not carry information; rather, it protects the inside components of the cable, which are responsible for signal transmission and interference protection.

A shield made of copper and metal.

This component protects the transmission from radio wave interference, as its name suggests. You probably have dozens, if not hundreds, of nearby devices that are emitting radio signals unless you live in a remote area. The gadget you’re using is sending and receiving radio waves unless you’re reading this on printed paper.

The dielectric insulator inside

The entire point is that this portion of the cable does nothing. The metallic shield is kept apart from the core wire by the insulator.

Centered core

The actual work is done by this component, which also serves as the cable’s electrical grounding. While often constructed of copper, these components can also be built of steel with a copper wire covering.

Benefits and drawbacks of coaxial cables

An honest sales pitch should always contain a list of the advantages and disadvantages of any technology.

Coaxial Cable Benefits

  • minimal signal loss
  • high calibre over short distances
  • cables that last
  • the price is low

Coaxial Cable Cons:

  • large cables
  • loss of signal over a large distance
  • loss of signal at the link

Coaxial speaker cable utilization

How to choose the right Coaxial Speaker Cable for Your System

It’s time to focus on what makes coaxial cables a superior option for speaker cables now that we’ve established what they are, what they’re used for, and what benefits they provide. A reliable choice for transmitting high-quality audio signals from an amplifier or receiver to speakers is a coax speaker wire.

Many audio systems link to an externally powered subwoofer via RCA coaxial cables. You are already aware of the procedure required to assemble coaxial speaker cables if you are able to connect your own connectors to a speaker cable. By manually cutting off the connectors, removing the shielding, and wrapping the braiding into a single thread between the two, you can accomplish this task.

Coaxial speaker cables: advantages and drawbacks

Coaxial cables are a great choice since they transmit high-frequency signals with less interference from your receiver/amplifier to your speakers. The benefits of using a coaxial speaker cable include high-speed data transfer and professional-level audio quality.

Advantages of coaxial speaker cable:

  • With the lengths required for residential audio systems, signal degradation is not a problem.
  • Cables are remarkably resilient.
  • Excellent shielding against signal interference or noise
  • Simple to install

Disadvantages of Coaxial Speaker Cable:

  • You might be able to get by with “out-of-the-box” speaker cable options now available.
  • With very lengthy cables, signal loss is a problem.
  • Cables are large, making them more difficult to conceal.
  • less flexible and heavier than alternative solutions

Types of cable

Coaxial speaker cables can be used with either flexible coaxial or semirigid coaxial cable constructions. Because flexible coaxial bends far more easily than rigid coaxial, as their names suggest, you can tell the two apart with ease. Semirigid coaxial, however, offers improved shielding for reduced interference.

Although flexible coax is more readily bendable to make the connection, semirigid coax is still the preferable option for the best audio quality. The Triax, dual coax, and twin axial cable types also function, but their extra characteristics might make things more difficult without offering useful solutions.


Speaker cables that use coaxial technology deliver a connection that is incredibly resilient while also producing a sound of a professional caliber. Coaxial speaker cables can be the solution for you if you’re having significant problems with signal noise or interference.
