What Is Coaxial Speaker Cable and What Do You Need to Consider?

interviews

Speakers are a vital component in any audio system. They are the reason you have music or sound to listen to. If you have high-quality speakers in your home theater, but you’re listening on tinny computer speakers, it won’t be as enjoyable. It’s crucial that the speakers and your receiver – which amplifies the signal from the amp – are well-matched.

What is Coaxial Speaker Cable?

coaxial speaker cable is an electrical cable used to connect speakers to amplifiers or other audio equipment. “Coaxial” refers to the cable having two conductors insulated from each other and arranged in a cylindrical shape. The inner conductor is typically made of copper, while the outer conductor is made of aluminum.

Coaxial speaker cables are available in various sizes and lengths, so choosing the right size for your needs is essential. The most common sizes are 12 gauge and 14 gauge. 12-gauge cable is thicker and can carry more current, making it ideal for use with high-powered amplifiers. 14-gauge cable is thinner and is better suited for use with lower-powered amplifiers.

When choosing a coaxial speaker cable, you must consider the impedance. This is measured in ohms and indicates how much resistance the cable has to the electrical current. A higher impedance means less current will flow through the cable, which can cause problems with sound quality. For most applications, a coaxial speaker cable with an impedance of 16 ohms or less is considered low impedance and will work well.

For a high-quality coaxial speaker cable, look for one made from oxygen-free copper (OFC). This type of copper has been treated to remove impurities, resulting in a cleaner signal path and improved sound quality.

What Types of Coaxial Speaker Cables Are There?

There are three main coaxial speaker cables: unshielded, shielded, and twisted. Unshielded coaxial cable is the most common cable used in audio applications. It comprises two conductors – an inner conductor and an outer conductor – that are wound around each other.

The inner conductor is typically made of copper or aluminum, while the outer conductor is typically made of copper braid or aluminum foil. Shielded coaxial cable is similar to unshielded coaxial cable but has an additional shielding layer that helps reduce interference from electromagnetic fields.

The twisted pair coaxial cable comprises two insulated conductors twisted around each other. This type of cable is often used in applications where there is a need for high levels of immunity to electromagnetic interference.

How Long Should the Speakers Be?

When it comes to speaker cable length, there are a few things you need to take into account. The first is the size of your room. The larger the room, the longer the cable you will need. The second is the wattage of your amplifier. The higher the wattage, the longer the cable you will need. The third is the impedance of your speakers. The higher the impedance, the longer the cable you will need.

Assuming you have a standard-sized room and are using a standard amplifier with standard speakers, here are some general guidelines for speaker cable length:

• For 4-ohm speakers, 12-gauge wire is sufficient for up to 50 feet, and 14-gauge wire is sufficient for up to 100 feet.

• For 8-ohm speakers, 16-gauge wire is sufficient for up to 50 feet, and 18-gauge wire is sufficient for up to 100 feet.

• For 16-ohm speakers, a 20-gauge wire is sufficient for up to 50 feet, and a 22-gauge wire is sufficient for up to 100 feet.

Why Is Flexibility Important in a Coaxial Speaker Cable?

To understand why flexibility is essential in a coaxial speaker cable, it is first necessary to understand what coaxial cable is. Coaxial cable, or “coax” as it is commonly referred to, is a type of electrical cable that consists of two conductors separated by an insulating layer. The inner conductor is typically made of copper, while the outer conductor is made of aluminum.

Coaxial cable is used in various applications where electrical signals must be transmitted over long distances with minimal interference. One such application is audio systems, where coaxial cables connect speakers to amplifiers.

The flexibility of a coaxial speaker cable is essential because it allows the cable to be routed in tight spaces and around obstacles. This can be critical in-car audio systems, where space is often at a premium. Additionally, flexible coaxial cables are less likely to suffer from kinking or pinching, which can damage the inner conductor and cause signal loss.

What is the Difference Between Shielded and Unshielded Coaxial Speaker Cables?

Coaxial speaker cables are made of two insulated conductors twisted around each other. The inner conductor is usually made of copper, and the outer conductor is usually made of aluminum. The aluminum outer conductor acts as a shield against electromagnetic interference (EMI). The shielded cable is then wrapped in an overall protective jacket.

Unshielded coaxial speaker cables do not have an aluminum outer conductor, so they are not as effective at shielding against EMI. However, they are less expensive and easier to work with than shielded cables.

When choosing a coaxial speaker cable, you need to consider the run length, the type of equipment you are using, and the level of EMI protection you need.

Conclusion

Overall, a coaxial speaker cable is an excellent option for anyone looking to improve their audio setup. It’s essential to consider the gauge and quality of the cable when making your purchase, as well as how long of a run you’ll need. With a little bit of research, you should be able to find the perfect coaxial speaker cable for your needs.
