coaxial speaker cables

A coaxial speaker cable is a type of electrical cable that is used to connect speakers to amplifiers and other audio equipment. It is composed of two or more insulated wires that are twisted together, with one of the wires typically being a ground wire. Coaxial speaker cables are often used in home theater systems and car audio systems.

If you are looking to upgrade the audio in your home theater or stereo system, you may be wondering what kind of speaker cable to use. Coaxial cable is a popular option, but there are a few things to consider before making your purchase. In this article, we will go over some tips for choosing the right coaxial speaker cable.

what is a coaxial speaker cable?

A coaxial speaker cable is an electrical cable with two conductors, usually of different diameters, that are twisted together around a common axis. The inner conductor is typically made of copper or copper-clad aluminum, while the outer conductor is typically made of oxygen-free copper or silver-plated copper. The dielectric (insulating) material between the two conductors can be made of various materials, including air, polyethylene, polypropylene, Teflon, or PVC.

Coaxial cables are used in a variety of applications, including computer networking, audio/visual equipment, and radio and television broadcasting. They are also commonly used to connect loudspeakers to amplifiers in home theater systems.

The difference between a coaxial cable and other types of cables.

There are many types of cables that are used for various purposes, but one of the most common is the coaxial cable. This type of cable is often used for audio and video applications. There are several benefits to using a coaxial cable over other types of cables.

One advantage of a coaxial cable is that it can carry a signal with less interference than other types of cables. This is because the signal travels through the center of the cable, surrounded by an insulating material. This reduces the amount of electrical noise that can affect the signal.

Digital coax cable

Digital coax cables are coaxial cables that are specifically designed to carry digital signals. This cable has a greater bandwidth than conventional coaxial cables, which makes it more capable of taking in data. This makes it ideal to use in high-definition audio and video applications. Digital coax cable can be used to connect devices like televisions, DVD players, satellite receivers and other home theater systems. A computer can also be connected to a television or monitor.

Coaxial vs. RCA Cables

The most commonly used cables to connect audio equipment are RCA cables. Although coaxial cables are not as common as RCA cables, they have advantages.

Coaxial cables are made up of a single conductor, which is protected by a shield. This shield reduces interference and noise. The coaxial cables are also more tightly wound than RCA cables. This helps maintain signal quality.

The Components of a Coaxial Cable

Coaxial cables are made up of two conductors made from metallic metals and are insulated from one another. The signal is carried by the inner conductor, while the shield acts as the shield. The shield prevents interference from other movements and protects the inner conductor against damage. The dielectric insulation layer on a coaxial cable helps to keep the conductors separate and separated.

Core conductor

A coaxial cable is an electric cable that has an inner conductor and is surrounded by a tubular insulation, usually plastic, and then shielded by braided wire. This protects the inner conductor against interference. Coaxial cable connects televisions to each other or other electronic devices. It can also transmit RF signals between devices. The coaxial cable’s core is a hollow cylindrical center with a diameter approximately 0.5 inches (1.3cm).

Jacket made of plastic

Most people associate coaxial cable with standard TV cables, which are found in homes all over the country. Although the coaxial speaker cable looks very similar to these cables, it is specifically designed for use with speakers and not televisions. A coaxial speaker cable is made up of a copper wire that runs through its center and is surrounded by a protective plastic jacket. The jacket protects the wire from moisture and keeps it out.

The installation process of a coaxial speaker cable

Whether you’re a music enthusiast or just want to improve the sound quality of your TV, installing a coaxial speaker cable is a great way to do it. Although it may seem like a daunting task, the installation process is actually quite simple and only takes a few minutes. Here’s what you need to know about installing a coaxial speaker cable.

The first thing you need to do is find the right spot for your speakers. You want to place them so that they’re facing the room and not too close to any walls. Once you’ve found the perfect spot, it’s time to connect the cables.

Start by connecting one end of the cable to the “OUT” port on your receiver or amplifier.

The difference between shielded and unshielded coaxial speaker cables

There are two types of coaxial speaker cables- shielded and unshielded. The main difference between the two is that shielded cables have an extra layer of insulation around the inner conductor, while unshielded cables do not.

Shielded cables are typically used in applications where there is a lot of electromagnetic interference (EMI), such as in industrial environments. The extra layer of shielding helps to reduce the amount of EMI that can get into the signal and cause problems.

How to select the right gauge for your coaxial speaker cable

When it comes to choosing the right gauge for your coaxial speaker cable, there are a few things to keep in mind. The first is the length of the run. The longer the run, the thicker the cable you’ll need to prevent signal loss. The second is the amperage rating of your amplifier. The higher the amperage, the thicker the cable you’ll need to prevent fire hazards. And lastly, you’ll want to consider what type of connectors you’re using. If you’re using banana plugs, for example, you’ll need a thicker cable than if you’re using bare wire.

How to Connect Your Speakers Using Coax

If you are using an amplifier, you will need to connect the positive and negative terminals of the amplifier to the positive and negative terminals of the speaker. You will then need to connect the ground wire of the amplifier to the ground wire of the speaker.

If you are using a speaker cable, you will need to connect the positive and negative terminals of the cable to the positive and negative terminals of the speaker. You will then need to connect the ground wire of the cable to the ground wire of the speaker.

Why Doesn’t Coax Work Well for Premium Speakers?

Coaxial speaker cable is not the best choice for connecting premium speakers to an amplifier. The main reason is that the impedance of the cable is too low. This results in a loss of high frequencies, which makes the sound quality less than ideal.

How to Choose the Right Coaxial Speaker Cable?

Choosing the right coaxial speaker cable is essential for achieving high-quality audio performance in your home theater or audio setup. Coaxial speaker cables are designed to transmit audio signals from your amplifier or receiver to your speakers. Here are comprehensive details on how to choose the right coaxial speaker cable:

Cable Gauge:

The gauge of the cable refers to its thickness and is measured in American Wire Gauge (AWG). In general, lower AWG numbers indicate thicker cables. Thicker cables have lower resistance and can transmit signals over longer distances without significant signal loss.

For most home audio setups, 16 AWG or 14 AWG cables are sufficient. However, if you’re running long cable runs, consider using 12 AWG cables to minimize signal loss.

Cable Length:

Measure the distance between your amplifier or receiver and your speakers to determine the cable length you need.

It’s a good practice to buy slightly longer cables than you need to account for any unexpected changes in your setup.

Cable Material:

Copper is the most common material for coaxial speaker cables due to its excellent conductivity. Oxygen-free copper (OFC) is preferred for its high purity and reduced signal loss.

Some cables use silver-plated conductors, which can offer even better conductivity but are often more expensive.

Insulation and Shielding:

Look for cables with high-quality insulation and shielding to protect against interference and signal degradation.

Foil and braided shielding are commonly used to block electromagnetic interference (EMI) and radio frequency interference (RFI).

Connector Types:

Coaxial speaker cables usually have two types of connectors: RCA and 1/4-inch or 1/8-inch TS/TRS connectors.

Ensure that the connectors match the input and output jacks on your amplifier/receiver and speakers. Consider the type of connectors you need when purchasing the cable.

Bi-Wire or Single Wire:

Some speakers support bi-wiring, which involves separate connections for the woofer and tweeter components. If your speakers support bi-wiring, you may need specialized cables with two sets of conductors.

Brand and Quality:

Choose reputable brands and models known for their quality and durability. Reading reviews and seeking recommendations from experts can be helpful.


Set a budget for your speaker cable. While high-end cables can provide excellent performance, there are reasonably priced options that can also deliver good results.

Personal Listening Preferences:

Consider your listening preferences and the quality of your audio equipment. If you have a high-end audio system and are an audiophile, investing in higher-quality cables may be more important.

Audition and Testing:

If possible, audition different cables with your system to determine which one sounds best to you. The difference in audio quality between cables can be subtle, so trust your ears.
