The 4 Fundamental Terms You Need To Know When Shopping For Coaxial Speaker Cable

With the number of coaxial speaker cable options available to buy, it can be a little overwhelming. To make things easier for you, this article breaks down the four terms you’ll need when shopping for coaxial speaker cable: impedance, gauge, power handling and jacketing.

What is Coaxial Speaker Cable?

Coaxial speaker cable is a type of electrical cable that is designed to carry audio signals. It consists of two or more conductors (the inner and outer conductor) that are surrounded by an insulating material. The inner conductor is typically made of copper, while the outer conductor can be made of aluminium or copper. Coaxial speaker cable is often used in home theatre systems and other audio applications where long runs of cable are needed.

What are the Benefits of Using Coaxial Speaker Cable?

If you’re looking to improve the audio quality of your home theatre system, you may be wondering if upgrading to coaxial speaker cable is worth the investment. In short, the answer is yes! Here are some of the benefits of using coaxial speaker cable:

1. Coaxial cable offers superior sound quality.

2. Coaxial cable is less likely to pick up interference from other electronic devices.

3. Coaxial cable is easier to install than other types of speaker wire.

4. Coaxial cable is more durable than other types of speaker wire, so it will last longer.

5. Coaxial cable is available in a variety of sizes and lengths to fit any need.

How to Select the Correct Coaxial Speaker Cable Size

There are a few things to consider when selecting the correct size coaxial speaker cable for your application. The first is the gauge of the wire. The vast majority of coaxial cables for home audio use are either 16 or 18 gauge. The next is the capacitance rating of the cable. This is generally expressed in picofarads per foot (pF/ft). The lower the capacitance, the better.

Another factor to consider is the impedance of the cable. Most coaxial cables for home audio use have an impedance of 75 ohms. However, some high-end cables have an impedance of 50 ohms. The last thing to consider is the length of the run. The shorter the run, the less resistance there will be and thus, less signal loss.

In general, most people will be fine with a 16 gauge cable for runs up to 50 feet and an 18 gauge cable for runs up to 100 feet. If you have a longer run or want to be sure you have no signal loss, then you can step up to a higher quality 14 gauge or 12 gauge cable.

How to Connect Coaxial Speaker Cable

Coaxial speaker cable is one of the most popular types of speaker wire, and for good reason. It’s relatively inexpensive, easy to find, and it works well with most home theatre systems.

If you’re looking to connect your coaxial speaker wire to your home theatre receiver, there are a few things you’ll need to do first. Here’s a step-by-step guide on how to connect coaxial speaker cable:

1. Begin by stripping the outer jacket off of the speaker wire. You’ll want to strip about 1/2″ of insulation off, exposing the inner conductor wire.

2. Next, twist the inner conductor wires together so they’re tight and secure.

3. Once the inner conductor wires are twisted together, screw on a coaxial connector (also called an F-connector). Make sure the connector is screwed on tight so there’s no risk of it coming loose.

4. Now take the other end of the coaxial cable and repeat steps 1-3. When you’re finished, you should have two connected ends of coaxial cable, ready to be plugged into your receiver.

5. Finally, plug each end of the coaxial cable into the appropriate input/output ports on your receiver. In most cases, the input will be labelled “TV” or “ANT.” The output will usually be labelled “OUT.”

And that’s all there is to it! Connecting coax


If you’re in the market for some coaxial speaker cable, then it’s important to know a few key terms before you make your purchase. We hope that this article has helped to clear up any confusion and that you now feel confident when shopping for coaxial speaker cable. Thanks for reading and happy shopping!
