No matter if you have a basic system, an all-in-one unit, a home theatre like Pioneer AVH-2550NEX review or hi-fi cost no object, you got to have speaker cables. These cables have a great impact on the audio of your sound speakers depending on the installation. If you’re interested, scroll down below to learn more about this.
The speaker cables are the electrical cables or wires used to link the loudspeaker system to the amplifier. Like any other cables, it has capacitance, inductance, and resistance as its three primary electrical components. The most significant among them is resistance. Low-resistance cable enables more power coming from the source down to the speaker coil, this means that having more power equals more sound. When the resistance is bigger than 5% of the speaker’s impedance, that’s the point where resistance begins to affect the speaker’s performance.
Resistance is influenced by two vital elements; the cross-section area and length of the wire. Shorter wires contain lesser resistance. When setting up for your speakers, it’s best to lessen the wire lengths as possible. But see to it that you can still position properly your speakers. It is also crucial that both the speaker’s wire lengths are identical to assure that both will possess a similar impedance rating. The cross-sectional area of the wire is implying about the gauge or thickness of the cable. The lesser the gauge or thicker the wire is, the lesser its resistance.
Speaker Cable Materials
There are several metal choices you can use as the conductor of your speaker cable.
- Copper is the most widely used among all the materials. It is also the cheapest but provides a high level of conductivity. One downside of it is it will oxidize, producing a thin layer of copper oxide which may cover the wire’s surface. If this occurs, this will become a high-resistance blockade between the amplifier or speaker and cable where the connection materializes. Typically, you can use screw pillars to break the layer of oxide. However, eventually, its effect will transpire which is increases the wire’s level of resistance.
- Silver offers just a bit lower resistance than copper. Though it also oxidizes, it is much pricier than the copper.
- Gold is the most expensive of them all since it doesn’t oxidize and gives the lowest resistance. But because of its price, it is seldom used as speaker wire.
In general, the purer the metal used in the wire, the higher the price will be. Several various levels of purity are offered for cables and whether if this conveys a substantial benefit to the sound or not will depend on your liking that is for you to determine with yourself.
Ultimately, the most significant thing about speaker cable is that the wire gauge should be appropriate for the length of your wire and the impedance of your speakers. Everything outside this is it’s for you to check out. All of us have different sound preferences, so test some out, listen for yourself for you to find out what’s best for you.
