Coaxial speaker cable: All You Need To Know in Detail

The usage of coaxial speaker cables is increasing day by day. Almost every second home uses this gadget. However, coaxial speaker cables are used for various transmission purposes in which TV Antennas, cable boxes, videos, and audio signals are the most prominent in all. What kind of benefits people can take from these cables? What sort of essential components are used in the manufacturing process? Nevertheless, a person who is seeking hefty information regarding coaxial speaker cables. This article is far enough to resolve all complex queries efficiently.

Importance of coaxial speaker cable:

This electrical signal transmits RF signals from source devices to the input devices. RF denotes the radiofrequency range which spans from the top end of the audio spectrum to the bottom end of the infrared spectrum. Following specialties are given,

• 20kHz to 300kHz
• The term coaxial is the reflection regarding the construction of the cable. It indicates the connection of the axis between the woven shielding and the core of the cable.

Historical perspective:

When the invention of television came into being, the importance and demand for speaker cables increased. In 1858, the speaker cable was introduced. However, 22 years later, almost all kinds of advancements were accomplished. Therefore, its demand has been increasing for domestic purposes in this regard.

Structure of coaxial speaker cable:

Its structure is not complex therefore it is simply easy to manufacture a speaker cable. You will not face any kind of difficulty in this regard. It incorporates a cylindrical shape which makes it impressive and excellent on the market. In addition, the conditions of color and thickness can vary by keeping people’s choices in mind. There are four main components which are given,

1. Metallic Shield
2. Dielectric Insulator
3. Plastic Jacket
4. Core Conductor

Alignment of components:

As far as the core conductor is concerned, a dielectric insulator surrounds it. Such insulator contains solid plastic, foam plastic, and air with spacers. The other following components are given as,

• Copper is an essential material that is used for the core.
• Stranded copper and copper-plated steel are also prominent components in this regard.
• For shields, braided copper wire is mostly used.

Innovations by quality:

If you are seeking some specific shields which are hefty and useful according to quality. Then there are two critical shields which are given as,

• Combining one aluminum foil layer and one layer of braided copper wire.
• The combination of two layers of aluminum foil and two layers of braided copper wire.
• Performance increases with the increase of shielding layers
• Several shields increase cable thickness and make it less flexible. Therefore, it is not considered desirable in this regard.
• The installation of polyvinyl chloride is also used as a final layer. This jacket provides resistance to ultraviolet light and oxidation. Moreover, it is a material of fire resistant and water resistant as well.

Merits:

There are a lot of benefits in which essentials are given as,

• Coaxial speaker cables are easily affordable
• These cables are easy to install and expand
• They are highly durable devices
• Their heat transfer rate is very high which helps the device to cool down quickly.
• They have high brand-width transmission
• Ensures highly frequent applications without any difficulty
• They are more resistant to the RFI and EMI

De-Merits:

As far as the disadvantages of coaxial speaker cables are concerned the followings are given,

• When you add several shields then it is obvious that thickness will increase. Moreover, the material becomes stiffer and harder. The installation will be more complex therefore, you can take thickness as a disadvantage as well.
• You will have to ground a coaxial speaker cable.
• If faults come around somewhere in one cable. Then it can create damage to the entire network therefore, it is referred a great danger for your cable device.

What are the prominent factors in coaxial speaker cable?

Various parameters create high differences in quality. However, the few essentials are the most prominent in this regard.

• Thickness
• Construction
• Impedance also distinguishes one cable from the other regarding quality
• The type of dielectric material used in cable
• The types of connectors

The factor of Impedance:

Impedance makes a clear difference between two coaxial speaker cables. For example, a cable that contains 50Ω and one with 75Ω impedance. This feature makes users able to create differences in quality.

1. Cable with 50Ω Impedance:

In addition to all of that, 50Ω is used for radio transmitters and transmitter antennas. Such cables are also used for highly frequent digital transmissions and coaxial Ethernet networks. This is useful but quality changes according to the selection of increasing numbers of impedance.

2. Cable with 75Ω Impedance:

These cables are used for many domestic purposes nowadays. Almost everywhere people use the 75Ω impedance version. These cables make ensure the audio and video transmissions. However, they are also used in telecommunications.

The systems like RF video transmission and cable television have a total dependency on this impedance. There are various impedances but their usage is less common such as 93Ω, and 52Ω impedances, and vice versa.

3. Radio Guide coaxial cables:

The usage of this cable is common in the household sector. It was used to classify coaxial cables since World War 2. The two letters R and G are indicated by numbers and letters. Radio-guided coaxial cables make people able to distinguish based on some specific properties and specifications. The following characteristics are given,

• Outer diameter
• Core wire diameter
• Type of dielectric material and shielding
• Impedance
• Variety of connectors used based on RG Code

Categories of cables with numerous applications:

Type of Coaxial speaker cable	Diameter of core	Outer diameter	Impedance factor	Applications
RG-6/U	1.024mm	6.86mm	75 Ω	Satellite television, cable television, and cable modems
RG-6/UQ	1.024mm	7.57mm	75 Ω	Same as RG-6/U with greater shielding material
RG-7	1.3mm	8.13mm	75 Ω	Same as RG-6/U
RG-8/U	2.17mm	10.3mm	50 Ω	Amateur radio
RG-8/X	1.47mm	6.1mm	50 Ω	Same as RG-8/U

Types of connectors used in coaxial speaker cables:

There are numerous connectors used and N-type connectors, SMA-type connectors, RCA-type connectors, and BNC-type connectors are the most prominent.

1. N-type connector:

These connectors involve lower microwave frequencies which are almost 18GHz. However, broadcast equipment and communications are the best applications by far.

2. BNC connectors:

These connectors are designed for a frequency of 10GHz. It is considered stable upto the 4GHz while above can cause radiating of signals and heat losses.

1. F-type connectors:

It is designed for a frequency of 1 GHz. These connectors are applicable for antenna cables and television cables.

2. RCA connectors:

It handles the frequency up to 10MHz. These are highly applicable to videos and audio transmissions.

CONCLUSION:

It is conclud that coaxial speaker cables are use by the household sector all over the world. Moreover, It incorporates a lot of benefits and disadvantages in the forms of construction material, a factor of durability, and vice versa. In addition, If you want to know the difference between two coaxial power cables then impedance is essential to make it ensure. Moreover, there are numerous versions available on the market by quality. These particular features make the coaxial speaker cables impressive compared to the other devices.
