How to Install Coaxial Speaker Cable

When it comes to Coaxial Speaker Cables, there are several factors that need to be taken into consideration. The first step is to strip the jacket and insulation of the cable. Then, you will be able to see the core wire. You can then cut the ends of the cable or leave them intact to save time and effort.


Copper coaxial speaker cable is a very durable alternative to speaker wire. This cable is typically copper but may also be made from steel with copper wire coating. Before attempting to install this type of speaker cable, make sure you know its pros and cons. First, you need to measure how many feet the cable needs to reach the speakers. This measurement should be double-checked or triple-checked to eliminate any errors. After you have the correct length, strip the insulating layer from the coax cable. Be careful not to damage the cable.

The core of a copper coaxial speaker cable is made up of a copper conductor wrapped in a dielectric insulator. Copper is commonly used for the core wire, while copper-plated steel is another common material for the center conductor.

Plastic jacket

There are several methods for removing the plastic jacket of the coaxial speaker cable. The first is to remove the insulation on both ends of the cable. This will make the wire more rigid and reduce the amount of work required when installing it. Once the jacket is removed, you can attach the speaker cable to the positive connector on the amplifier or speaker. You must be careful when doing this as any exposed space may affect the signal.

There are several types of coaxial speaker cables. The most common is the flexible coaxial cable. This type has a polymer strand inside the cable. The polymer strand creates an air space between the conductor and the jacket. Because the air has a lower dielectric constant, the inner conductor can be a little larger than the outer conductor at the same cutoff frequency, which minimizes ohmic loss. In addition, some coaxial speaker cables are silver-plated for a smoother surface. While the smooth surface of the inner conductor is more convenient, it also stretches the current path and concentrates the current at its peak, increasing ohmic loss.

Four layers of shielding

The four layers of shielding on the coaxial speaker cable are a key factor in the quality of your audio experience. Each of these shields protects the signal from external radio waves, which are produced by many electronic devices. The shield is composed of a metal outer layer and an insulator, which separates it from the core wire.

In some types of coaxial speaker cables, there are two layers of aluminum foil or braided copper wire. The thickness of these layers affects their flexibility. In addition to shielding, speaker wires are often covered with plastic jackets. Polyvinyl chloride is well-known for its resistance and toughness.

Dielectric insulators

The coaxial speaker cable is made of two main parts: the center conductor and the dielectric insulator. The center conductor is covered with a metal braid, which insulates against noise and other interference, and a dielectric insulator surrounds it. Dielectrics can be made of different materials, but they are typically made of solid plastic or foam.

A good dielectric resists the flow of electrons through the material. This property enables the cable to maintain a low capacitance. Dielectric absorption can result in coloration in audio signals, which results in the loss of fine detail at low levels.

Low impedance

Low-impedance coaxial speaker cable is available in different lengths. In order to find the right length for your system, you must measure the distance from the receiver to the speaker. It is recommended to measure twice or three times to avoid errors. You should also add a few feet to the length to ensure that the speaker wire is long enough. Once you have the proper length, strip the insulation on the coax cable. Be careful not to damage the cable during the process.

The length of the cable will influence the impedance of the signal. A long cable will have a high impedance while a short one will have a low impedance. Short coax is not recommended because it can cause your system to have poor sound quality.

Resistance to interference

Coaxial speaker cables offer better sound quality than their parallel counterparts. The coaxial construction allows the transmission of high-frequency signals and provides excellent shielding against electromagnetic interference. These speaker cables are also bulkier and are not as flexible as thin speaker wires. Furthermore, these cables contain multiple components, such as wires, which can cause them to have more capacitance than thin speaker wires. This increased capacitance can cause instability in some systems. Nevertheless, the risk of electromagnetic interference is very low.

The resistance to interference of coaxial speaker cables depends on their length and impedance. The cable’s impedance should be at least 50 ohms. These cables are typically used in industrial and commercial applications. However, for broadcast television, 75 ohms is commonly used.
