How to Choose the Right Coaxial Speaker Cable


In this article, you will learn about coaxial speaker cable, which is the type of speaker wire that connects your audio equipment to an amplifier or receiver. You’ll also find out what other types of speaker wire are available and how they compare to coaxial cable.

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 equipment. It is made up of two conductors, an inner conductor and an outer conductor, that are wrapped around each other in a spiral. The inner conductor is typically made of copper or aluminum, while the outer conductor is usually made of copper.

Coaxial speaker cable is often used in home theater systems and car audio systems. It provides a good connection between the speakers and the amplifier and is less likely to pick up interference than other types of cables.

Types of Speaker Cables

There are three main types of speaker cables:

1. Coaxial: This type of speaker cable has two inner conductors (positive and negative) surrounded by an insulating material and an outer conductor (ground). Coaxial cable is typically used for home theater systems and car audio systems.

2. Twisted Pair: This type of speaker cable has two inner conductors (positive and negative) that are twisted around each other. Twisted pair cable is typically used for computer speakers and some home theater systems.

3. Optical: This type of speaker cable has one inner conductor (positive or negative) surrounded by an insulating material and an outer conductor (ground). The optical cable is typically used for high-end home theater systems and some car audio systems.

Coaxial vs. Speaker Wire

There are a few different types of speaker wire out there, but the two most popular are coaxial and speaker wire. So, which one is right for you?

Coaxial cable is made up of two insulated wires that are twisted around each other. This type of cable is typically used for audio applications because it can carry a signal with very little interference.

Speaker wire, on the other hand, is made up of multiple strands of uninsulated wire that are bundled together. This type of wire is less expensive than coaxial cable and it’s easier to work with. However, speaker wire is more susceptible to interference than coaxial cable.

Tips for Choosing the Right Wire for Your Needs

There are a few things to consider when choosing the right wire for your needs. What is the gauge of the wire? The lower the number, the thicker the wire. Also, what is the insulation material? Some options include PVC, polyethylene, or Teflon. Lastly, how long do you need the cable to be?

The most important factor in choosing a speaker cable is probably gauge (diameter). Most people choose 12-gauge for their main speakers, but 14-gauge is also popular and will save you some money. For runs longer than about 30 feet, you might want to consider using a 10-gauge cable instead.

The next consideration is conductor material. Copper is by far the most common choice because it’s an excellent conductor and relatively inexpensive. Silver-plated copper is also available and provides slightly better performance, but it costs quite a bit more. Oxygen-free copper (OFC) is another option that provides even better performance than regular copper but can be very expensive.

Finally, you need to decide on insulation material. The most common choices are PVC (polyvinyl chloride), polyethylene, and Teflon. Each has its own advantages and disadvantages. PVC is inexpensive and easy to work with but it’s not as durable as the other options. Polyethylene is more durable than PVC but it can be difficult to work with. Teflon is very durable and


With so many different coaxial speaker cable options on the market, it can be tricky to know which one is right for your needs. However, by following the tips in this article, you should be able to narrow down your choices and find the perfect cable for your system. Don’t forget to take into account the type of connectors you need, the gauge of the wire, and the length of the run when making your decision. With a little bit of research, you’ll be sure to find the perfect coaxial speaker cable for your setup.
