Coaxial speaker cable - Full guide

Coaxial speaker cable

Today we will go through the guide on everything you need to know about the most common cable in the professional audio industry: the coaxial speaker cable.

The first coaxial cable was created and patented by Oliver Heaviside in 1880
The many uses of this type of cable kept it relevant even after more advanced methods were developed, as the master in the field of transmitting signals from radio to television and small and large amplification systems before we review how you will use the coaxial cable.
Let’s thoroughly explain the technology behind it.

What is a coaxial cable?


A coaxial cable is connected to Wired networks or electrical devices that transmit high-frequency signals, such as a radio, TV or even a speaker to an amplifier(coaxial speaker cable).
The cable consists of two conductors, an inner conductor and an outer conductor, that are twisted together. The inner conductor is typically made of copper, and the outer conductor is typically made of aluminium. The cable is covered with an insulating material such as PVC. Professionals recommend  to use a tough cable. Because it conducts signals better

We will use a speaker as an example to demonstrate the connections.

The inner conductor is connected to the speaker’s positive terminal, and the outer conductor is connected to the negative terminal. The twisting of the two conductors prevents interference from other electrical devices.

There are 3 common types of coaxial cables.
Each type is more or less suitable for different uses
The main changes between the types of cables are the latency of the signal transmission
and the possible signal transmission distance

Coaxial cables types


1. The most common coaxial speaker cable is the RG-6 cable. 

This cable is made of copper and has a diameter of 6mm. The RG-6 cable is typically used for long runs, from a receiver to a speaker in another room.

2. The next most common type of coaxial speaker cable is the RG-59 cable. 

This cable is made of copper and has a diameter of 5mm. The RG-59 cable is typically used for shorter runs, from an amplifier to a speaker in the same room.

3. The last type of coaxial speaker cable is the RG-11 cable. 

This cable is made of copper and has a diameter of 11mm. The RG-11 cable is typically used for long runs, from a receiver to a speaker in another building.

Impedance in coaxial cables


The duration of the impedance in different types of cables determines the typical use for which they are suitable and the maximum signal transmission distance
For example, cables with 50 ohms can transmit communication up to a distance of 185 meters
In analog equipment, even if the impedance is more or less, the equipment can tolerate it, and there will be reasonable signal transmission
But unlike digital equipment, it is very important to know exactly the appropriate impedance for the type of use. Otherwise, it simply won’t work
and worse, could damage the equipment
In our case of a coaxial speaker cable, the exact impedance you will need to accurately transmit signals to the speaker is 75 ohms.

The benefits of using a coaxial speaker cable


Using a coaxial speaker cable has many benefits over a traditional speaker cable.
1. Coaxial speaker cables transmit signals at the highest speed and quality

2. are made with a copper core and an outer layer of insulation. The copper core helps to conduct the electrical signal from the amplifier to the speaker, while the outer layer of insulation protects the inner core from interference. This design helps to reduce the amount of electromagnetic interference the speaker cable can produce.

3. They are also more durable than traditional speaker cables. The copper core and outer layer of insulation help to protect the inner core from damage. This means coaxial speaker cables can withstand more wear and tear than traditional speaker cables.

Possible disadvantages of coaxial cable

The disadvantages of coaxial cables are usually not related to coaxial speaker cable
Here are the cons:

  • May cause signal disruption over long distances
  • Heavy and large cables without the possibility of hiding

Tips for Choosing the Right Coaxial Speaker Cable


After you have understood for professional use with audio, it is recommended to use only a coaxial cable to solve signal problems and hear the best quality sound
Here are 5 professional tips that will help you make the right choice:

1. Consider the gauge of the cable.

One of the most important things to consider when choosing coaxial speaker cables is the gauge, or thickness, of the cable. The thicker the gauge, the better the quality of the sound. However, thicker cables are also more expensive. So, it’s important to find a balance that fits your budget.

2. Look for a cable with OFC copper conductors.

Oxygen-free copper (OFC) is the best type of conductor for speaker cables. It provides superior sound quality and is less likely to degrade over time.

3. Choose a cable with a low capacitance rating.

Capacitance is the measure of a cable’s ability to store electrical energy. The lower the capacitance, the better the sound quality.

4. Make sure the cable is shielded.

A shielded cable is wrapped in a material that protects it from electromagnetic interference (EMI). This interference can distort the sound. So, it’s important to ensure that your cable is shielded.

5. Consider the length of the cable.

The length of the cable you need will depend on the distance between your speakers and your audio receiver. So, be sure to measure the distance before you purchase your cables.

How to install a coaxial cable for a speaker


If you’re looking to install a coaxial cable for your speaker system, there are step-by-step tutorial. This part will cover what you need to know for installation, including what cable to use and how to connect it.

When it comes to speaker wire, there are two main types – stranded and solid. The stranded wire comprises multiple small strands of wire, while the solid wire is a single piece. Stranded wire is more flexible, making it easier to work with and more expensive. Solid wire is less expensive, but it’s also more difficult to work with.

Which type of wire should you use for your speaker system? It depends on your budget and your level of expertise. Solid wire is the way to go if you’re working with a tight budget. Stranded wire is better if you have a little more to spend.

Once you’ve decided on the type of wire you will use, it’s time to connect it to your speakers. You’ll need to strip the insulation off the wire’s end if you’re using solid wire. To do this, use a wire stripper or a sharp knife. Be careful not to damage the wire itself.

Once the insulation is removed, twist the wire around the speaker’s binding post. Using stranded wire, you can twist the wire around the binding post. If the binding post is threaded, you can screw the wire on.

Tighten the binding post until the wire is secure. Then, repeat the process for the other speaker.
And that’s it. The coaxial speaker cable has been successfully installed. Enjoy the high-quality sound and, this time, without problems!

Troubleshoot a coaxial speaker cable


If you’re having problems with your coaxial speaker cable, there are a few things you can do to troubleshoot the issue. First, check to ensure the cable is properly connected to the speaker and the receiver. Next, check the cables’ connections at the ends to ensure they’re tight and secure. Finally, check the cable itself for any damage or kinks.

If you still can’t get the cable to work correctly, there may be a problem with the cable itself. In this case, you’ll need to replace the cable.
