Are Your Speakers Popping? Here’s How to Fix the Crackle

23/11/2023

Speaker crackle and popping is a common issue in audio, affecting live venues and studios alike. Finding the root of an audio problem can be tough, requiring a mix of knowledge, experience, and trial and error. This guide is here to help you identify what might be causing that awful noise every time you turn your speakers on.

In a hurry?

For those seeking a quick fix, here are some easy steps to finding the cause of the crackle. Follow each step until you identify the problem:

  • Check that all cables are plugged into your speakers properly – both power and audio cables
  • Check the condition of the cables to see if they’re worn out
  • Swap cables for spare ones
  • Check the connections inside the speaker to make sure no key components are loose or damaged
  • Check the connection on the audio source, whether it’s a mixer, audio interface, or AV amplifier
  • Switch your devices off to safely and carefully clean the connectors with microfibre cloths, solvent, and/or cotton swabs. If you see visible rust, try a deoxidiser

Why do speakers pop?

Speakers almost always pop due to some kind of issue with the connection between the source and the speaker. Usually, this is something simple, like a not-fully plugged-in cable, a damaged cable, or a lot of dust or rust inside the connectors. Whatever the reason, the problem is probably that your amplifier and speaker are not connected properly.

A cable could have been knocked out of place during a performance, while cleaning, or by a pet, for example. Sometimes the cables get twisted or trapped under things and get crushed, damaged, or just pulled loose and out of place. Alternatively, the output connectors on the amplifier or the input connectors on the speaker could be loose, damaged, or dirty.

If your amplifier-speaker connection isn’t the issue, it may be that there are damaged components inside your speaker. Live PA speakers, in particular, that see a lot of use will simply degrade over time with the frequency and intensity of use. Components get knocked out of place, solder becomes loose, and the thin wiring that runs to the speaker drivers can easily become slackened or damaged.

As with any electronics, they’ll just occasionally need maintenance or replacement.

Fundamentally, speakers receive voltages that are then converted into movement by the drivers. If that voltage is interrupted and suddenly drops to zero, the sudden stop in movement of the speaker drivers will cause a pop sound. If it happens multiple times in quick succession, it’ll sound more like crackling.

How to fix any popping and crackling in your speakers

Firstly, unplug the cables and reconnect them to see if that fixes anything, or if you have any backup cables, try them and see if the issue persists.

It’s also worth periodically switching them off and thoroughly cleaning them with cotton swabs, microfibre cloths, and a cleaning solution to remove dust. If they’re particularly old, they may have started to rust and require a deoxidiser instead of a standard solvent.

However, although it’s usually a faulty connection between the amplifier and speaker that causes the crackle, sometimes this isn’t the case! So, if all else fails, it may be worth checking inside the speakers for loose, damaged components, or loose internal wiring.

Digital pops and clicks

Digital pops and clicks tend to sound a little different but have the same overall cause. This is essentially caused by a sudden discontinuation of the voltage that makes up the audio signal, which means that a digital-to-analogue converter is the source of the faulty connection.

Amplifiers, audio interfaces, digital mixers, or digital stageboxes could all be at fault here, as they all have built-in converters. The answer will depend on what your audio system consists of and is used for.

To correct these sounds, it’s worth checking the cables or input and output connectors between your converters and speakers. Whatever your signal chain is, look at these areas, clean connectors, swap cables, and check the inside of your speakers.

Whilst the digital pops and clicks can sound different, the causes and fixes are pretty much the same, although what might be causing the issues might be slightly different, or more hidden within your audio path.

Crackle on vinyl

There are two main issues that can cause vinyl crackling. Due to the nature of the format, some crackling and low-level noise is pretty much expected with vinyl. However, it can get overbearing and worse with time, due to a buildup of either static electricity or dust on your vinyls.

This crackling comes from an interruption in the connection between the turntable’s needle and the grooves in the record. Things like dust, dirt, debris, and static will make it harder for the needle to read the vinyl by sticking to the grooves either by tangible causes or static, which sends an additional voltage through the needle.

It’s worth cleaning your records with a microfibre cloth and dedicated cleaning or anti-static solutions to correct this. If this doesn’t work, check your turntable’s needle or cartridge. It’s worth gently cleaning the needle or swapping cartridges, but you need to be delicate with this, as you don’t want to snap the needle.

FAQs

How do I get rid of the speaker popping sound?

To get rid of that pesky speaker popping sound, check connections outside of the speaker, like cables, and make sure they’re in place properly. If that doesn’t solve the problem, check and clean the connectors on the speaker and your output device to avoid the buildup of dust and rust. Then, check connections inside the speaker for solder breakdown and loose components, if you’re familiar with the workings of the speaker or know somebody who is, you can get it repaired.


Can popping damage active speakers?

If your speakers don’t have protection circuitry, popping can damage your speakers. Since it stops or creates sudden movement in the driver, this can create wear and tear.


Why is my speaker buzzing and crackling?

There are a few causes behind speaker buzzing and crackling, but it’s mostly about the connection between your output device and speaker. Cables, amplifier issues, loose connections, damaged internal components, or excessively loud volumes can all cause this. Make sure all of your connections are secure and properly plugged in!
