Why Does My Subwoofer Smell Burnt?
Your subwoofer tends to have a burnt smell mainly because of the voice coil on the subwoofer. This voice coil is an element that receives sound signals from the amp, after which the process of converting these signals begins within the unit.
These voice coils tend to be stuck to the subwoofers using copious amounts of adhesive or glue, which is why too much heat due to overuse can cause the adhesives to burn, leading to this kind of smell.
It is, therefore, important to ensure that you use the subwoofer up to its given capacity and not beyond it. In many subwoofers, this kind of phenomenon usually takes place for a limited period of time, after which the smell stops, but it can also go on for longer with some.
What Causes Overheating?
Overheating is the main cause that leads to your subwoofer smelling burnt. What, then, causes overheating? Let’s take a look at some reasons behind a subwoofer overheating so that you can keep those in check whenever you use the subwoofer.
Overpowering the Subwoofer
Overpowering the subwoofer is associated with the amp that you use in your sound system. It is important for the amp and the subwoofer to be compatible so that they can both function effectively. You should maintain this by keeping the right crossover frequency across all the units.
In case your amp has too much power, then this can cause it to send an extremely strong signal or current to the subwoofer which can then cause it to overheat in the process of trying to manage the current on its own and converting it into waves.
This overheating can then cause the glue on the voice coil to start burning.
If you keep listening to your music at high volumes, then this can lead to overheating as well. The subwoofer is meant to enhance low frequencies of sounds from your music but loud volumes can end up sending too much power to it.
Once again, this will end up putting too much pressure on the subwoofer as it will have to work harder to handle the sounds. This can then cause the coil to heat up more than usual, causing the adhesive to start burning and leading to an unpleasant burning smell.
Warped audio can also cause the subwoofer to overheat beyond measure. Whenever you play a song, sound or audio from another source that does not blend in well with the rest of the audio, then this can cause the sound that your subwoofer receives to be warped.
It can then lead to overheating since the distorted audio will create issues for the subwoofer in terms of converting the sound signals.
Do New Subwoofers Smell?
New subwoofers tend to smell a bit burnt because it can take time for the unit to get used to working within your requirements. This can thus cause the glue on the voice coil to burn easily whenever the unit heats up due to usage.
This is a pretty normal occurrence that you do not need to worry about too much since the smell should ideally dissipate once the glue burns off.
Do Subwoofers Smell While Loosening Up?
Your subwoofers might take some time to loosen up from the tightness once you start using the unit. This mainly involves the suspension of the subwoofer becoming unrestricted so that it can start working properly by enhancing the bass and low frequencies.
This process does not usually involve any kind of burning smell because the elements that are loosening up are not connected to the glue of the voice coil. If this happens, then there might be an issue with the unit itself or you might be using the subwoofer incorrectly.
Should I Be Concerned If My Subwoofer Smells Burnt?
If your subwoofer smells burnt due to the voice coil, then you do not need to be too concerned since the smell should fade away and clear up once all the extra adhesive on the coil burns up.
On the other hand, if the smell continues to last for a few days, then you might have a problem in terms of your unit itself or an individual element of the unit. Make sure you figure out what the issue is and get the unit or component repaired or replaced.

Is the burning smell coming from a subwoofer normal?
It’s normal from a new subwoofer to have a slight burning smell when you first turn it on. This is because the glue needs time to burn off though so this should go away in a few days or so if you’ve been using it for a while. It’s not like the glue is over heating and burning all at once, it takes a little bit of time so don’t worry about too much.
Why does my subwoofer smell like burnt rubber when it plays?
If you notice that your subwoofer smells like burnt rubber when you are playing it then this is because your voice coils are getting hot and causing this burning rubber smell to come into the air.
Is it normal for a new subwoofer to smell?
Yes, it’s normal for a new subwoofer to smell when you first turn it on. This is because the glue needs time to burn off though so this should go away in a few days or so if you’ve been using it for a while.
Why do my subs smell like burning?
You may be wondering why your subwoofers smell like burning. It could be because of a number of reasons, such as excess glue or burnt voice coils. Make sure you figure out what is causing this and try to fix it as soon as possible. To understand the issues, please re-read this article.
What does burning voice coil smell like?
Burning voice coil smells like burning rubber or tire, and it is very pungent. If you smell this, your voice coil is probably burning and you will need to check it out.

The burning smell is usually mild and is often compared to a bandaid smell. Sometimes, however, it could even be a stronger and more prominent burning smell that is similar to smoke or a grill. You might need to be more cautious of the latter.
Is It Possible to Fix a Burnt Subwoofer?
A fully burnt subwoofer might mean that the voice coil or the cone itself is damaged. You can try to fix the cone, but you might need to replace the voice coil or even the entire unit. I wrote an article that explains how to fix a burnt subwoofer.
Can Subwoofers Catch Fire?
While rare, a subwoofer can catch fire if you keep using it in an unsuitable way, such as by overpowering it, using warped audio or loud volumes.
Can excess glue on the voice coil be the reason for subwoofer smell?
Yes, excess glue on the voice coil can be the reason for the subwoofer smell. When when you are using the voice coils and they overheat, it burns the excess glue on it.
Does a new subwoofer always smells burnt?
There are a few of hem that do. Typically there’s burn off smell with a new subwoofer (new subs) during the break in period.
Where does the burnt smell originate from?
There are multiple reasons such as: excess glue burning, voice coil glue, burning electronics, voice coil heats, enhanced bass causes voice coil overheats; glue begins to burn around the speaker basket it happened with a brand new subwoofer. Luckily there are plenty of homemade youtube videos to help you. Either way excess glue and voice coil overheats are the main causes. Also you shouldn’t forget that the glue to attach voice coils can be a cause as well. All in all the voice coil issue and excess glue has to be checked out first.
Why does my subwoofer smell like glue?
There are multiple reasons, such as excess glue burning, voice coil glue, burning electronics, enhanced bass causing voice coil overheating; glue begins to burn around the speaker basket it happened with a brand new subwoofer. Glue is used in almost all speakers and they smell because of that.
Why is my subwoofer getting hot?
There are many reasons, but the most common would be voice coil. It’s important to check it out, because if you continue using the system, you run a chance of burning your subwoofer out.
What does a blown sub smell like?
A blown subwoofer smells like every other type of burnt electronics, which means it can be pretty smoky depending on what is burning. It can also smell like a hot rubber melting.
Can a subwoofer catch fire?
It’s possible, but it doesn’t happen often. The main causes of subwoofer fire would be either the amplifier or the speaker alone, and that this is why you don’t want to mistake any other smells for this.
