Coaxial Speaker Cable: The Ultimate Buying Guide

Technology is evolving, and we’re doing our best to keep our audiences and clients informed of the changes.

The coaxial cables we’re about to discuss are commonly used in our businesses, workplaces, and homes for the efficient working of various audio and video components.

Coaxial cables are used in business areas such as the telecommunications and internet industries and personal use.

You must know how to choose the proper coaxial cable for your office or home before making a snap judgment.

Stay with us, and let’s dig into the exciting world of coaxial cables.

What are coaxial speaker cables?

A coaxial speaker cable, to put it simply, is an electrical cable that sends RF signals from devices at the source to devices at the receiving end.

These cables are progressively being adopted in many professional home audio systems to guarantee consistent sound quality.

The radiofrequency spectrum of coaxials ranges from 20 kHz to 300 GHz.

For starters, the main distinction between coaxial and RCA audio cables is that, unlike RCAs, coaxial transmit digital signals.

As a result, they provide greater bandwidth that deals with a more stable connection.

Compared to regular audio cables, the external cable has better levels of durability and strength.

These cables can be used with any subwoofers/speakers with a length of 75 cm to 6 meters.

Some coaxial speaker cables are made specifically for use with subwoofers. So they provide a secure connection as well as high-quality audio.

Most microphones, especially professional ones, use mic cables with 3-pin XLR connections.

Because of its low signal-to-noise ratio, XLR cables are preferred as microphone cables.

What materials are used in coaxial speaker cables?

Each component of a coaxial cable determines the materials utilized in its construction.

First, the rod in the center is mostly made of copper-plated steel.

However, stranded copper will be used instead if that material isn’t accessible for manufacturing.

Solid plastic, foam plastic, or air with spacers are the most often used materials for dielectric insulators.

A braided copper wire is typically used for the shielding component of the cable.

A silver-plated braid is used instead in higher-quality and other versions of a coaxial cable.

Some even employ two shields simultaneously, which is achieved by mixing aluminum foil with braided copper wire.

Even coaxial cable designs go through two shielding layers, like aluminum foil and braided copper wire.

Shielding improves RF signal transfer performance while also reducing signal loss.

The main drawback is that the cable thickens and becomes less flexible, which may be an issue for some.

The outer layer of coaxial cable, known as the “jacket,” is often made of PVC (Polyvinyl Chloride), which is fire-resistant in most circumstances.

Even some are resistant to oxidation, UV light, and water.

What is the purpose of coaxial cable?

Coaxial cables are used in radiocommunication, telecommunication, and wireless systems for various applications.

They’re utilized for things like TV antennas, HD and cable television, ethernet internet, audio, and video transmission, etc.

For different applications, different cable types and connectors are employed.

High-speed cable internet, cable TV, and satellite TV use the most common cable types (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 used for radio applications.

The Benefits and Drawbacks of Using a Coaxial Cable

Coaxial cables are widely used nowadays for radio transmissions, telecommunications, WiFi systems, cable TV, and cable modems, among other things.

Even though it is an old piece of technology, it is still used in many industries worldwide for daily labor and operations.

The fundamental reason for this is that the benefits of using a coaxial cable far outweigh the downsides.


A coaxial cable’s first key advantage is less vulnerable to electromagnetic and radio-frequency interference.

Furthermore, the line supports applications with frequencies up to 50 MHz and higher.

Another advantage of coaxial cable over other cables, such as twisted-pair cables, is that it has both fast transfer rates and bandwidth transmission.

Finally, coaxial cables are pretty inexpensive in today’s market, and their simple architecture makes installation a breeze.

Because it is affordable, you can expand it, and it is noted for its durability, which is among the best of all cables.


The primary disadvantage of a coaxial cable is that a single cable failure can bring a network to a halt.

Instead of ruining the network and its components, this is easily fixable by just introducing a new cable.

Another disadvantage of utilizing a coaxial cable is that it must be grounded, which means that it must carry a live electric current to function.

Finally, as previously said, the last disadvantage of this type of cable is that it can be heavy and rigid, making installation more difficult.

Types of Coaxial Cables

Coaxial Digital Cable

The shape of this sort of coaxial cable is similar to that of an RCA cable. However, it transmits digital impulses rather than analog signals.

The bandwidth of digital coaxial cables is typically higher, and these cables are also thicker.

Because the design of a regular coaxial cable and a digital coaxial cable is nearly identical, you can request digital coaxial cables before purchasing.

Digital Audio Coaxial Cable

This cable connects two audio devices. These cables connect an external speaker or amplifier to your PC or laptop.

Both ends of these have an RC jack. Some manufacturers color-mark the stops for the user’s convenience.

Coaxial Cable 75 Ohm

This type of cable impedance is 75 ohms, as the name implies. Heavy industry and commercial uses use these cables.

These cables can efficiently transmit data without sacrificing quality or strength.

It is a multipurpose cable that easily handles video, audio, and speech signals.

Coaxial Cable, White

These wires are the industry-grade standardized for internet, satellite, and cable TV services.

These cables preserve the general decoration of your room or office intact since the white color easily blends in with the room’s interior.

Coaxial Cable for Television

These cables connect the devices to the VCRs, TVs, and satellite dishes.

They come in two versions: one with a male connector and the other with a male-to-female connector.

The wires are plated with gold or silver to boost the transmission quality.

Wrap Up

In a nutshell, coaxial speaker cables allow for the lossless transfer of digital audio signals. However, this isn’t the only benefit.

They also deliver superb audio output and can power even the most advanced audio and video devices.

Speaking of the current year, coaxial cables are now the most common transmission cables used in homes and businesses.

Whether you need transmission cables for an internet connection, Cable TV, CCTV cameras, or any other device, coaxial will hook you up.
