Every thing You Want To Know About Speaker Wire

Despite the fact that the market is flooded with Sound Bars and Wi-fi Audio system, there are nonetheless a number of audiophiles and residential theatre lovers who like conventional audio system that it’s essential wire. You’re spending tons of or 1000’s of {dollars} on residence theatre and audio tools. However one space the place even professionals get confused is the Speaker Wire. Some search for the most cost effective possibility accessible whereas some go for the costliest and top-of-the-line one. There are a whole lot of debates surrounding the Speaker Wire.

On this information, allow us to perceive the significance of Speaker Wire. We’ll see the necessary traits that it’s essential search for in a Speaker Wire. There are a number of extra issues we’re gonna cowl right here. So, if you’re a newbie, then we hope this text will clear a few of your doubts.

What Is Speaker Wire?

A Speaker Wire or Speaker Cable is {an electrical} conductor that’s accountable for making {an electrical} connection between the ability amplifier and the speaker.

In its easiest type, the core of a Speaker Wire is made up of both stable or stranded copper. A protecting PVC Sheathing then surrounds the core to stop interference and exterior noise.

Because the speaker wire is just like a daily electrical wire, does this imply we are able to use any copper wire because the speaker wire? No. Don’t do that. You might blow up your audio system.

Despite the fact that the aim of speaker wires is to hold electrical alerts from a supply equivalent to an amplifier to the speaker, this doesn’t imply you may rip your spare extension wire and use it as a speaker cable.

There are specific bodily and electrical traits of the Speaker Wire that differentiates it from a daily electrical wire.

Traits Of Speaker Wire

The primary goal of the speaker wire or speaker cable is to hold low-voltage electrical present from the ability amplifier to the speaker. The speaker upon receiving this present will oscillate the coil forwards and backwards in a magnetic subject.

As one finish of the coil connects to the speaker cone, it additionally oscillates with the coil and thus creates sound waves. That is an oversimplification of the working of a speaker however you get the concept.

The takeaway right here is that it’s the accountability of the Speaker Wire to hold the electrical present to the speaker with very minimal delay and in addition the full-frequency audio alerts and energy.

So, what’s the necessary attribute of the speaker wire that makes this attainable? There are a number of essential parameters and traits of a speaker wire however the one which wants the utmost consideration is its Resistance.

Resistance Of Speaker Wire

The Electrical Resistance of a wire or any electrical element is its capacity to dam or prohibit the circulate of electrical present.

If the wire has increased resistance, it’s going to block the present circulate from the ability amplifier to the speaker. So, as an alternative of delivering full energy to the speaker, the wire wastes a whole lot of energy as warmth and the speaker underperforms (generally it doesn’t even carry out).

So, this implies we want a decrease resistance wire. However how low is sweet? What determines the resistance of a speaker wire?

There are a number of components that decide a wire’s resistance. However the three necessary ones are:

  • Conductivity
  • Size of the Wire
  • The thickness of the Wire

The conductivity of a fabric is its capacity to conduct electrical present. Everyone knows that copper is an effective conductor of electrical energy. Therefore, we use copper as the principle conductor for all our electrical wiring.

Even most speaker wires use copper on the core. One other widespread however not preferable possibility is copper-clad aluminum. Copper has considerably much less resistance than aluminum. However as aluminum is rather a lot cheaper than copper, some speaker wire producers use it as a substitute.

We suggest pure copper wires.

Coming to the opposite issue that has an impression on the resistance of the wire is its size. Shorter wires have decrease resistance than longer wires. It’s because the electrical present has to journey extra distance, which can lead to a lack of sign and energy.

So, hold the size of the wire as quick as attainable.

Subsequent, we have now the thickness of the wire. After we say thickness, we truly imply the cross-sectional space of the wire. Because the cross-sectional space of the wire will increase i.e., its thickness will increase, electrons have extra space to circulate and consequently, the resistance is much less.

This implies, utilizing a thicker wire.

Wire Gauge

However how thick is sweet sufficient? We measure the wire’s thickness utilizing its gauge as specified by the American Wire Gauge or AWG.

We already made an elaborate information on AWG and Wire Gauge Chart. Do test it out for an in-depth understanding of wire gauges.

However on a short observe, the bigger the “gauge” variety of a wire, the thinner the wire is. We all know that is complicated. For example, the diameter of a 12 AWG Wire is 2.05 mm whereas it’s only 1.63 mm in the event you take the 14 AWG Wire.

From the above dialogue, it’s clear {that a} shorter, thicker, and copper wire is the very best speaker wire mixture. The next is a small suggestion from our finish for the gauge and size of copper speaker wire you can think about relying on the impedance of your speaker.

  • 4 Ω Audio system: 20 AWG for 10 ft, 18 AWG for 15 ft, 16 AWG for 20 ft, 14 AWG for 40 ft, 12 AWG for 60 ft, and 10 AWG for 100 ft.
  • 6 Ω Audio system: 20 AWG for 15 ft, 18 AWG for 20 ft, 16 AWG for 35 ft, 14 AWG for 60 ft, 12 AWG for 90 ft, and 10 AWG for 150 ft.
  • 8 Ω Audio system: 20 AWG for 20 ft, 18 AWG for 30 ft, 16 AWG for 45 ft, 14 AWG for 80 ft, 12 AWG for 120 ft, and 10 AWG for 200 ft.

If you’d like the very best expertise, then we suggest not going over 50% of this size for respectable sound output.

Frequent Core (Conductor) Materials In Speaker Wire

We already touched on this subject within the earlier part. However allow us to perceive somewhat bit extra. The 2 widespread conductors utilized in speaker wires or speaker cables are Copper and Copper-clad Aluminum.


100% Pure Copper Wire is the very best speaker wire. Interval. It has been an business secure for a number of a long time.

Copper has a comparatively low resistance and is a superb conductor of electrical energy. Additionally, copper wires can be found on all gauges.

You possibly can go for a stable copper wire or wire with a number of strands. A number of sorts of analysis present that it doesn’t make a major distinction.

One drawback with pure copper wire is the prospect of oxidation. Whereas the remainder of the wire is insulated with plastic or PVC materials, it’s close to the termination that causes the oxidation drawback.

Oxidized Copper will lose its conductivity and in addition its resistance will increase. Cashing on this, some producers are producing “Oxygen-free” Copper Wire.

These fancy wires price considerably greater than common copper wires, however the efficiency enchancment may be very marginal.

Copper-clad Aluminum

The second hottest speaker wire materials is copper-clad aluminum (CCA). In its primary type, the core of the wire is Aluminum. However the floor of the wire has a skinny layer of copper.

Worth is the principle benefit of this materials as the price of aluminum may be very much less while you evaluate it with pure copper.

So, many speaker wire or speaker cable producers promote CCA Wires as a budget-friendly different to copper wires.

Observe that the conductivity of aluminum and even copper-clad aluminum continues to be lower than that of copper. Additionally, the resistance is barely greater than copper in the event you take the identical size and gauge wires.


There’s a third wire that has a distinct segment market within the audiophile neighborhood. It’s the Silver Wire.

Silver is a superb conductor of electrical energy, even higher than copper. The resistance of silver is lower than that of copper. This implies you will get away with increased gauge wire (keep in mind, the upper the gauge, the thinner the wire) than their copper counterparts.

However the price of silver wire may be very excessive. Even then, some high-end audiophiles with fancy cash to spend use silver wires.

How To Terminate Speaker Wires?

Speaker Wire Termination means utilizing an acceptable connector to attach the wire to the gadget, be it the ability amplifier or the speaker itself.

The kind of termination is determined by the terminals accessible in your speaker in addition to the amplifier.

One of many easiest methods to terminate the speaker wire is through the use of solely the naked wire with none connector. That is attainable in case your tools has spring-loaded terminals.

Alternatively, you need to use flex pin plugs as an alternative of naked wires if you’re anxious about exposing the steel a part of the wire and threat oxidation. Take into account concerning the gauge of the wire earlier than buying the flex pin plugs.

The most well-liked solution to join a speaker wire between amplifiers and audio system is through the use of Banana Plugs. With these plugs, you may merely and rapidly join or disconnect the wire from the terminals.

In case your gadgets have binding put up fashion terminals, then one other helpful connector is Spade Plugs.

No matter the kind of connector you utilize, be sure it’s gold-plated. Gold doesn’t oxidize simply. Therefore, we see a whole lot of connectors with gold plating.

Issues To Contemplate When Shopping for Speaker Wire

We’ll attempt to summarize the subject by itemizing some important issues that it’s essential think about whereas searching for speaker wires.

Conductor Materials

After we converse of the core conductor supplies utilized in various kinds of speaker wires, then we have now pure copper, aluminum, copper-clad aluminum, oxygen-free copper, and silver.

Silver Wires are ridiculously costly whereas copper-clad aluminum wires are very low-cost. We predict the oxygen-free copper wire is only a advertising and marketing gimmick for copper wire with higher insulation.

Pure copper with sufficient plastic or PVC Insulation is our advice. Don’t even think about aluminum wires.

Size Of The Wire

Place your audio system in your required place. Measure the precise distance between the amplifier and the speaker. Then use the wire that matches that size exactly.

Okay. Don’t make the size so tight that the wire is suspended within the air. Hold a small quantity of room so that you can transfer or reposition your tools. However undoubtedly don’t go extra than what’s obligatory.

Wire Gauge

The gauge of the wire determines how skinny or thick the wire is. There are two extra issues that it’s essential think about earlier than figuring out the gauge of the speaker wire. They’re the size of the wire and in addition the speaker impedance.

As a rule of thumb, here’s a small listing of various AWG speaker wires which are made up of pure copper comparable to completely different lengths between the amplifier and the speaker and in addition completely different speaker impedances.

  • 8 Ω Audio system: 20 AWG for 20 ft, 18 AWG for 30 ft, 16 AWG for 45 ft, 14 AWG for 80 ft, 12 AWG for 120 ft, and 10 AWG for 200 ft.
  • 6 Ω Audio system: 20 AWG for 15 ft, 18 AWG for 20 ft, 16 AWG for 35 ft, 14 AWG for 60 ft, 12 AWG for 90 ft, and 10 AWG for 150 ft.
  • 4 Ω Audio system: 20 AWG for 10 ft, 18 AWG for 15 ft, 16 AWG for 20 ft, 14 AWG for 40 ft, 12 AWG for 60 ft, and 10 AWG for 100 ft.


Lastly, we have now the wire termination. Naked Wire, Flex Pin Plugs, Banana Plugs, Spade Plugs, and RCA Connectors are some widespread methods to attach the speaker wire to amplifiers and audio system.


There’s a steady debate across the subject of Speaker Wires. Some purchase an inexpensive wire to attach the audio system to amplifiers. However some audiophiles do a whole lot of analysis, and search for the best-performing speaker wires, even when they’re costly.

In a easy sense, a speaker wire is only a wire that carries {the electrical} alerts (audio and energy) from the ability amplifier to the speaker.

This doesn’t imply we are able to go simply use any electrical wire. In case you are considering of doing this, please don’t. You may trigger hurt to your audio system.

Despite the fact that a speaker wire is only a “wire”, there are specific issues that it’s essential search for earlier than shopping for one.

On this newbie’s information, we seemed on the fundamentals of speaker wires. We noticed some necessary traits of a typical speaker wire that it’s essential think about.

After that, we noticed the significance of wire resistance and the way completely different parameters equivalent to core materials, size of the wire, and in addition thickness of the wire have an effect on it.

We additionally noticed alternative ways to terminate speaker wires. Lastly, as a abstract, we listed out a few issues that any person who’s organising a house theatre or audio system should think about whereas buying a speaker wire.

We hope that this information might clear a few of your doubts concerning speaker wires or speaker cables. There are nonetheless much more issues surrounding speaker wires equivalent to wiring, the process to terminate utilizing completely different connectors, and lots of extra.

In case you are , we are able to cowl all these subjects. So, do tell us within the feedback part for any further info.
