Speaker Wire

Wed Dec 12, 2018


In day-to-day life, it’s easy to overlook the obscure things that make a huge difference in items we use such as the aglet on a shoelace or the ferrule on a pencil. This also occurs in the electrical industry. It goes without saying that when it comes to anything electrical, there’s a lot that goes on behind the scenes. Many different materials have to come together for it to work. When one aspect of it is missing, no matter how big or small, it can cause the entire electrical product to malfunction or not work, completely. Because of this, knowing what goes into making your electrical product can help prevent that from happening. One such item that does an important job without being well-known is the speaker wire. Speaker wire is something that many should be familiar with if you work with music or have knowledge of electrical engineering.


What is Speaker Wire

Speaker wire consists of two or more electrical conductors individually insulated by plastic or rubber. It's what makes the electrical connection between loudspeakers and audio amplifiers. It has three main properties which include capacitance, inductance, and resistance, with resistance being the most important. Wires that have low resistance gives the power source the ability to penetrate the speaker coil further. This means there will be more power and more sound through your sound source.

Another important aspect to speaker wires is the wire gauge. The wire gauge signifies the thickness of the wires. Thicker wires present less resistance to the flow of currents, which means they’re better for use in high power applications and long wire runs. Wire thickness is identified by AWG, or American Wire Gauge, where the lower the number means the thicker the wire. For example, a speaker wire with an AWG of 12 will be thicker than a speaker wire with an AWG of 18. Even though speaker wires with higher AWG may seem less enticing than those with lower AWG, they’re still viable options because they’re easy to work with and cost-effective.

RPP offers Speaker Wire that is made up of high strand count, insulated, oxygen-free copper wire conductors with an easy strip PVC jacket. It’s available in various conductor counts and AWG based upon your needs.


When is Speaker Wire used

As mentioned before, speaker wire is used between loudspeakers and audio amplifiers. It can increase the sound quality because of a greater signal flow. Because it has high power and low impedance, it can carry strong, amplified signals. This makes it great for applications in which power is necessary. If the speaker you’re using has low impedance (4 ohm to 6 ohm), a speaker wire with an AWG of 12 or 14 is your best bet. Speakers with a higher impedance (8 ohm to 16 ohm) will work fine with a speaker wire of any AWG.


How is speaker wire used

Speaker wire can be run inside walls and ceilings. Speaker wire with an AWG of 12 or 14 may be best suited for this application because of the length of the run. But for speaker wire that will be run normal distances, any gauge will work for any standard speaker installations.
