What You Need to Know When Buying a Coaxial Speaker Cable

Cable is something that can often be overlooked when buying an audio speaker. This is unfortunate because the cable you choose will affect the quality and sound of your speaker. In this article, we’ll give you everything you need to know about coaxial speaker cables so that you can choose the right cable for your speaker!

What is Coaxial Speaker Cable?

A coaxial speaker cable is a type of electrical cable that is used to connect speakers to amplifiers and other audio components. It consists of two conductors, one inner and one outer that are separated by an insulating material. The inner conductor is typically made of copper or aluminum, while the outer conductor can be made of various materials such as copper braid, aluminum foil, or plastic.

Coaxial speaker cables are designed to carry audio signals with minimal interference. They are often used in home theatre systems and car audio systems. When choosing a coaxial speaker cable, it is important to consider the gauge (thickness), length, and connectors.

Types of Speaker Cable

There are three main types of speaker cables:

  1. Coaxial: This type of speaker cable has two conductors, an inner wire, and an outer shield, which are surrounded by an insulating material. Coaxial cables are used for carrying audio signals from components to speakers.
  2. Optical: Optical cables use light to carry the audio signal from the source to the speakers. These types of cables are less common than coaxial cables and are typically used in high-end audio systems.
  3. Speaker Wire: Speaker wire is the most common type of speaker cable and is simply two insulated wires that carry the audio signal from the source to the speakers.

How to Tell Quality Cables from Cheap Ones

There are a few key things to look for when you’re trying to determine whether a coaxial cable is a high quality or not. First, check to see if the cable is made from the solid copper core material. This is important because it ensures that the signal will be transported clearly and without interference. Next, take a look at the dielectric insulation material; it should be made from high-quality foam that won’t deteriorate over time or with exposure to moisture. Finally, make sure that the shield surrounding the inner core is made from braided copper wire; this offers superior protection against electromagnetic interference.

Choosing the Right Length of Coaxial Speaker Cable

The length of the coaxial speaker cable you need depends on the specific application and where the speakers will be located. If you are just connecting two small speakers in a room, a short cable will suffice. But if you are running the cable across a large room or connecting multiple speakers, you’ll need a longer length of cable. The type of speaker also affects the required length of the coaxial speaker cable. For example, subwoofers generally require longer lengths of cable than standard speakers.

Coaxial speaker cables are typically sold in pre-cut lengths ranging from 1 to 100 feet. If you need a specific length that is not available, you can always cut and splice the cable to create your own custom length. Just be sure to use quality connectors and follow the manufacturer’s instructions for doing so. With a little bit of planning, you can easily choose the right length of coaxial speaker cable for your needs.


Coaxial speaker cables are a great option for anyone looking for high-quality audio. But before you buy, there are a few things you need to keep in mind. First, make sure you get the right gauge of cable for your needs. Second, pay attention to the length of the cable — too long and it will cause signal loss, too short and it won’t reach your speakers. Finally, be sure to get a good quality cable so that you can enjoy years of great sound.
