What Is A Coaxial Speaker Cable? 

Coaxial Speaker Cable

Coaxial speaker cables are signal transmission wires that can pass radio frequency signals between different electronic equipment with their coaxial cable speaker connector. These cables are generally used as transmission lines because they transfer signals at less loss. 

Standard electrical cables were the only choice of buyers. However, a Coaxial speaker cable is a favorite of customers today as it can convey a frequency range of 20kHz to 300GHz. Users can also use Coaxial cables to connect satellite dishes, television sets, and radio antennas to their respective receivers. Users started to use this type of cable in 1858. 

Components Of A Coaxial Speaker Cable

Coaxial speaker cable is built up of four different layers and therefore is highly reliable and durable. The speaker cable has a center conductor (a copper wire) that carries data and video. A non-conductive coating ( dielectric plastic insulator, which is a foam-like substance) is also there that protects its inner conductor.

The inner conductor remains safe within a cylindrical structure with additional shielding. This shielding is usually a braided mesh from copper then helps to shield the cable from electromagnetic interference (EMI)

There is also an outer coat made of plastic coating to reduce the possibility of injury to the signal transmitting components during setting or from environment-related pressures.

The second type depends on RG (Radio Guide standard).

 RG standard helps to categorize a coaxial speaker cable. All Cable types have R and G letter marks with a number informing users about the outer diameter, core wire diameter, Impedance, Shielding, and Dielectric type of the cables. Check some examples below.

RG-6 cables 

RG-6 cables

RG-6 cable can work with the GHz level signals more efficiently. It can run longer distances without audio or video signal loss and have thick dielectric insulation plus a gigantic conductor to provide a better quality signal. 

RG-59 cable

RG-59 cable has a thinner center conductor than the RG-6 and is the best choice for short runs and low-frequency transmissions. It is most in domestic settings and great for CCTV systems.

RG-11 cable

RG-11 cable is the best coaxial cable for HDTV. It offers a higher gauge, which provides more space for signals to move. Thus, the RG-11 cable is an expert at transferring strong HD signals at high speed. It also offers a lower attenuation level than RG-6 or RG-59 cable, making it adept at carrying data at longer distances.

Types of Coaxial speaker cable based on construction 

Following are the seven different types of coaxial speaker cables.

Coaxial speaker cable based on construction

Hardline Coaxial Cable

Hardline coaxial cables are types of cables best for supreme and promising signal transmissions. This cable uses compressed nitrogen as a restriction agent to prevent arcing and moisture intrusion. Besides, manufacturers use materials, including copper, steel, silver, or aluminum, to make the center conductor of Hardline coaxial cable. Moreover, this type of cable is larger in diameter than other forms of coaxial cables.

Flexible Coaxial Cable

Flexible coaxial speaker cable, just as its name suggests, can move as desired to fit the network and functionality of the electronic devices. It is the most common type of coaxial cable, commonly used in home video equipment and television connections. The flexible coaxial wire has a metallic central conductor enclosed by an adjustable polymer, functioning as the insulator. It also has an outer coat, acting as a defense against environmental stresses. 

 The best thing is, when it is necessary to enhance flexibility, users can switch the metallic core conductor with a stranded structure from a durable wire. They can also change the insulator with a polyethylene non conducting foam for more flexibility.

Semi-rigid Coaxial Cable

 After the initial forming operation, one cannot flex a Semi-rigid coaxial cable. However, with the help of special tools, users can bend them with their hands. It is crucial to remember that the outer non-ferrous copper layer of this cable is electrically stable. Therefore, can enjoy the dependable electrical performance and optimum phase stability with Semi-rigid coaxial cable.

Formable Coaxial Cable

Formable coaxial cable, typically known as the conformable coaxial cable, is the best substitute for the semi-rigid coaxial cable. This cable type has a flexible metal sheath in place of a copper covering outside. Therefore, one can reshape them by hand without any tools to meet the suitable cable configurations. They also offer electrical performance like other coaxial cables up to 18 GHz, and are best to use in satellites, antennas, etc.

Rigid Coaxial Cable

Rigid-line coaxial cables have mounted twin copper tubes, working as unbendable pipes. The outer surface of these cables is generally aluminum or copper. Further, these wires are best suited for indoor use between various high-power radio frequency (RF) transmitters. Moreover, these cables are  costly to construct and users must keep them dry to avoid unnecessary leakage between the two copper tubes. One of the top reasons to use these cable types is their capacity to reduce radiation losses.

Twinaxial Cable

Twinaxial cables have two insulated copper conductors in their core rather than one. These Twinax cables are adept for use in low-frequency digital and video applications. Some perks of using twin axial cable include lessening low-frequency magnetic noise, decreased cable loss, and a cost-effective alternative to conventional fiber cables.

Triaxial Cable

Triaxial cable or Triax wire has Copper Zirconium alloy inner covering and comes with an extra copper plait. This braid works as a defense against any outside current or noises. Therefore, this cable provides interference rejection and bandwidth increase. Besides, these cables are popular as they offer high frequency, are best-suited  for a wide range of signals, and have top insulation resistance to reduce signals too!

Can you use a Coaxial cable as a speaker cable? 

Yes! You can use a coaxial cable as a speaker cable. However, it would be best to replace the connectors to use the coaxial cable as a speaker wire. It would help if you replaced the standard F-connectors with RCA connectors first to make them work suitably with your speakers. 

Besides, here are some tips you must keep in mind to choose a digital coaxial cable if you want to use it in your home studio.

  • Think about applications ( why do you need a coaxial cable?) — Thinking about how you will use your coaxial cable is crucial before you buy one. Remember, each type of cable is well-suited for specific applications. Therefore, decide if your application will require short-range, long-range transmission, high or low frequencies before purchasing a coaxial cable.
  • Impedance ( Are you looking for 50 Ohm or cables with 75 Ohm?)— Impedance is nothing but an electrical circuit’s resistance to alternating currents expressed in ohms. So, you must buy a coaxial cable with an impedance that matches all components of a coaxial cable system to get rid of echoes, ghosting television images, and signal attenuation.
  • Environment ( Resistance to environmental factors) — If you want to install the coaxial cable underground, consider installing it with waterproof pipes to protect it from corrosive vapors or moisture. Thankfully, some manufacturers use hardened polyethylene cables with steel and silver coatings to make coaxial cables that are super resistant to environmental stresses. 
  • Working voltage and power rating is also a vital factor — The voltage of a coaxial cable travels through the center conductor. Check the maximum or “peak” voltage capacity of the coaxial cable and make sure it is not too high as a safety precaution.
  • Signal loss at different frequencies — Some coaxial cables are susceptible to signal loss at very high frequencies (VHF). So check if the manufacturers provide a foil or braided shield for VHF and UHF interference protection before buying a coaxial cable.
  • Pick the right Connector Type- There are different coaxial cable speaker connectors you can use with the coaxial cable mentioned above. While F-type connectors usually are best for connecting TVs, other connectors are also best for other devices. So make sure to check the connections that your device can accept before buying a coaxial connector.
  • HDTV Support- If you want to use a coaxial cable for your HDTV, you must get a top-quality coaxial cable. Best coaxial speaker cables are not affected by interference and signal loss.
