As an audio engineer or musician, selecting the cables for your audio production setup is essential for achieving high-quality sound. Various types of cables are available, each with unique features and benefits. We will examine coaxial speaker cable, XLR cables, RCA cables, and copper wire in audio production.
Coaxial Speaker Cable
A coaxial speaker cable is a wire that transmits audio signals from an amplifier to a speaker. It comprises a central conductor, typically made of copper or copper-clad aluminum, surrounded by a layer of insulation. An outer conductor is often made of copper or aluminum, braided or woven, then covers the insulation. This outer conductor serves as a shield, protecting the inner conductor from interference from external sources, like electrical wiring or other electronic devices.
One of the critical features of coaxial speaker cable is that they maintain the audio signal’s integrity as it travels from the amplifier to the speaker. We achieve this through the outer conductor, which helps to reduce the amount of interference that can affect the signal. We often consider coaxial cables the best option for long runs or environments with high electromagnetic interference.
Benefits of coaxial speaker cable
There are several benefits to using coaxial speaker cable in your audio system. These include:
Improved signal integrity: As mentioned, the outer conductor of a coaxial speaker cable helps reduce interference and maintain the audio signal’s integrity. This can cause a cleaner, more detailed sound with less distortion.
Enhanced durability: Coaxial cables are more durable than other speaker cables, as they withstand the rigors of long-term use. The outer conductor provides additional protection against physical damage, while the insulated center conductor helps to prevent corrosion and deterioration.
Easy installation: Coaxial cables are relatively easy to install, as they typically feature a single-wire design with a standard connector at each end. This makes them a convenient choice for both professional and DIY installations.
Versatility: Coaxial cables are available in various lengths and gauges, making them suitable for various audio setups. They can connect speakers to amplifiers and for other applications, such as connecting a TV to a sound system.
How to Choose a Coaxial Speaker Cable
When selecting a coaxial speaker cable, there are a few key factors to consider. These include:
- Length: The cable length will depend on the distance between your amplifier and speakers. Choosing a long enough cable to reach your speakers without excess slack is essential, as this can cause problems with signal quality.
- Gauge: The thickness of the conductor, referred to as the cable’s gauge, determines its ability to carry current. A lower gauge (thicker conductor) can handle more current and work well for longer runs or high-powered systems. However, it’s important to consider the cable’s resistance to ensure signal quality.
- Connectors: Coaxial speaker cable, such as RCA or banana plugs, typically feature standard connectors at each end. It is crucial to choose connectors that are compatible with your amplifier and speakers.
- Shielding: As mentioned, the outer conductor of a coaxial cable serves as a shield to protect the inner conductor from interference. The level of shielding can vary between different cables, with some offering more protection than others. If you are using the cables in an environment with a high level of electromagnetic interference, it may be worth investing in a cable with a higher level of shielding.
- Price: As with any product, coaxial speaker cable can vary significantly. While investing in high-quality cables, it is essential to balance this against your budget and the needs of your audio system. Sometimes, it may be worth spending extra for a cable with better performance or durability, while in other cases, a more affordable option may be sufficient.

XLR Cables
XLR cables, also known as balanced cables, are commonly used in professional audio systems to transmit balanced audio signals. They comprise three conductors–a positive, a negative, and a ground–surrounded by a shielded jacket. The three conductors are twisted together precisely, which helps to reduce interference and improve signal integrity. XLR cables are often used to connect microphones to mixing consoles, recorders, and amplifiers.
One of the primary advantages of XLR cables is their ability to transmit high-quality audio signals over long distances. They are also resistant to noise and interference, thanks to their balanced design and shielded jacket. In addition, XLR cables are easy to connect and disconnect, making them ideal for live audio production.
While XLR cables have some disadvantages, such as a higher cost and less flexibility than other cables, they are relatively durable and resistant to damage, thanks to their thick insulation and sturdy connectors. They are also relatively resistant to EMI (electromagnetic interference) and RFI (radio frequency interference) because of the balanced nature of the signal they transmit.
RCA Cables
RCA cables, also called phono cables or unbalanced cables, are commonly used to transmit audio signals between devices like a turntable and an amplifier. They are named after the RCA connector, a two-pin connector used to connect the cable to audio equipment.
One of the primary advantages of RCA cables is their simplicity and ease of use. They are easy to connect and disconnect from audio equipment and are relatively lightweight and flexible, making them easy to work in various settings.
Although RCA cables are a widely compatible and affordable audio transmission option, they have some drawbacks. These cables are less durable than other types and can become worn or damaged. They also have a lower bandwidth, which means they may not transmit high-frequency signals with the same accuracy as other types of cables, and this can lead to the audio signal’s loss of detail and clarity.
Coaxial Speaker Cable or… Copper Wire
Besides its conductivity and resistance to corrosion, copper wire has several other properties that make it a valuable material for audio production. It has a low resistance to the flow of electrical current, which means it can transmit audio signals with minimal loss. Copper wire is also relatively flexible, making it easy to work with and install in various audio production setups. Copper wire is also widely available and relatively inexpensive, making it a popular choice among audio engineers and musicians.
Copper wire is a popular choice in audio production because of its versatility and ability to withstand various environmental conditions. We can use it for various purposes, such as connecting speakers, microphones, and instruments. Copper wire is also resistant to temperature fluctuations and moisture, making it suitable for various settings.
On the downside, copper wire is not as resistant to interference as other cables and can suffer from signal loss over longer distances. Copper wire is also not as durable as other cables and can be easily damaged if not handled with care.
What It Boils Down To
Each type of cable has unique properties and benefits. Coaxial speaker cable reduce EMI and RFI interference, and XLR cables are excellent for transmitting balanced audio signals. RCA cables offer a user-friendly and straightforward option, and copper wire is budget-friendly and known for its high conductivity. The ideal cable for a specific project will depend on the project’s requirements, available budget, and resources.
