Subwoofer Making Noise When Turned On? Your subwoofer making noise when turned on, this phenomenon means your subwoofer is HUM. In this blog post, Hooke Audio will explain the reason why your Subwoofer Hum and how to fix it.

Common Reasons For A Subwoofer Making Noise When Turned On

Common Reasons For A Subwoofer Making Noise When Turned On

A subwoofer plugged into your stereo system rattling sound system or humming noise is not a tolerable experience. So what are the reasons?

Subwoofer hum can be caused by several things. It may just be a hum loop if you’re lucky. It’s normal to hear noises from ground loops and other factors. You can easily fix it.

The noise (or sound) is not too loud and doesn’t rise if you raise the volume.

It should happen if it does. If the sub isn’t functioning properly, you may need to check the power supply.

However, if there is a technical problem then you need to follow these steps. If the problem is due to the cable or power supply start by trying to plug the subwoofer into a different power socket.

It is possible to hear the noise, but it all depends on how loud you make it.

This could be due to a problem with the mains cable, or the subwoofer wire. This is because electromagnetic interference signals are responsible for the humming loop. Your subwoofer’s ability to produce a pitch that is higher or lower depending on how loud or power strip it is can be affected by electromagnetic interference signals.

Although the noise is audible, it doesn’t depend on volume.

This is due to humming ground loops. It’s for the resistors that connect the subwoofer power supply and the source unit to the sub. Finally, a loud noise is produced.

Causes of Subwoofer Hum

Subwoofer buzz or hum is a low-level sound system that can be heard when a powered or passive subwoofer hum turns on. It doesn’t matter if it is playing or not. The 60-hertz hum can be caused by being plugged into an AC power outlet.

Sometimes the hum can be easily detected. Other times, you will need to pay attention and really listen. You can fix the problem without having to filter out the humming noise. This also reduces audio signals. It usually takes only a simple change to the way that the subwoofer hum connects with the power strip.

How To Fix Hum in Subwoofers

How To Fix Hum in Subwoofers

There are many ways to eliminate the annoying hum. Try the following suggestions if the first doesn’t work.

Modify the polarity in the subwoofer’s connection. This is the easiest fix, as it only involves reversing your power plug’s orientation.

Sometimes one prong may be wider than the other which can prevent the reversal. To reverse the polarity in such cases, an AC ground adapter is recommended. These adapters are usually of uniform size and can be found at your local home improvement store.

Reverse other plugs. If components are connected to the same source (e.g. surge protector or the same power strip), the problem may not be with the subwoofer. You could also be using another two-prong AC plug. You can try it by changing the orientation of each plug one at a time to see if that makes any difference.

Disconnect the cables. If you place audio or power cables in bundles, they can bleed into each other and cause noise. Place cables apart to ensure that the electric fields generated by moving current don’t interfere with one another. Upgrade the audio cables with better shielding if you are unable to separate them sufficiently.

Switch outlets. Sometimes, the subwoofer’s hum can be caused by a ground loop. This happens when the subwoofer is fighting for ground loop possession from another device.

You should move the subwoofer to another AC ground adapter (AC circuit) in the room if you have another piece of three-prong equipment that is sharing the same power strip, wall outlet, or surge protector. To reach a wall outlet, you may need to use an extension cord cable.

Install an audio isolation transformer. An audio isolation transformer is an option if the other ground loop methods have not worked. They are made for powered subwoofers and can be connected in line with audio cables. An audio isolation transformer immediately resolves the ground loop subwoofer hum.

Do Subwoofers Make Noise?

Subwoofers and noise are contentious topics that make for interesting conversation and large sums.

Subwoofers make noise and must be loud enough to produce enough sound waves to make an impact on your environment.

They can have a profound effect on how the listener perceives music, sound effects, and other sounds in your room.

I began looking for ways to improve the sound quality of my subwoofer and make it louder in the room a few years back.

First, I was struck by the noise that the subwoofer produced when it was turned on full blast in my room.

It was quite surprising to me that the subwoofer’s bottom end made more noise than the top.

Why is the bottom end making noise than its counterpart? Although there are many possible causes, one common factor is that of the air moving over the box.

You will see the top-end models of subwoofers with baffles around their motors and drivers. These allow sound waves to flow freely without being blocked.

It is important to understand how sound waves are created. A vibrating object produces sound waves.

This is why you should know some basics about electromagnetism.

You should be very familiar with electromagnetism. When you study the theory behind the Physics of Magnets, you’ll soon see that there is a relationship between electron movement in a material and electron motion in surrounding space.

You can change the number or charge of electrons in a material by changing the size of its magnetism.

You can apply electricity to material and create an electric field that makes it resonate. These resonances can produce vibrations that can be heard by the human ear. The electric field that is created by the energy flowing through a AC circuit creates the electric field.

Now that you know how a resonant circuit produces sound waves, it is possible to understand how a subwoofer operates.

Subwoofer circuits work by creating an electrical field that flows through subwoofer coils. This field is directed towards the driver, which is the subwoofer’s attachment.

The sound waves traveling through the driver create energy, which is picked up inside the box.

The cone now moves back and forth creating vibrations that vibrate the speaker. These vibrations are then converted into sound waves that the speaker sends out. This is all to say that subwoofers make noise, and there’s a reason.

Why Does My Subwoofer Make A Static Noise?

Why Does My Subwoofer Make A Static Noise

Static electricity is also known as noise. It can be annoying for any music system or speaker system.

This noise can cause serious problems for your subwoofer and cause it to sound terrible.

Worse, you might spend a lot on a subwoofer and later find out that the person who sold it was wrong and you need to get a larger one.

Static noise is produced when an object is placed under the motor of the subwoofer. You need to understand why noise can occur in different amounts.

Let’s look at some causes and factors. Then, you’ll need to figure out how to fix the problem.

The subwoofer’s motor is a solid object so there is no static.

You will need to dispose of all the parts that make up the motor.

The main reason is that the stuff can be exposed to excessive heat, and even melt at high temperatures.

Exposure would look something like a power surge and constant motion with standing water.

You can use the red light in a car to determine if you’re unsure how to identify solid objects.

You can be sure that your subwoofer’s safety is assured if the red area is located on the motor or device driving it. Why is my subwoofer making static noise?

Bad or defective subwoofers can cause static. Poor or unrepairable joints between the subwoofer and motor can often cause static.

Most often, the subwoofer can be replaced with a new one.

Sometimes, however, both will need to be replaced together. Or, you can replace the subwoofer motor with a new one.

Make sure you install the new subwoofer woofer when replacing it with a replacement.

To test if the new subwoofer works well, you should also try it. Try the subwoofer that worked well before to see if it helps.

If static noise persists, the subwoofer can be used as normal, but you will need to modify the way it is connected to the amplifier.

Try changing the connections from the subwoofer and amplifier to see if that solves your problem.

If the problem persists, the subwoofer woofer may be damaged and must be replaced.

Be sure to research to find the best information for your problem.

This is the best way to do it yourself. It would be too dangerous for a technician to come to your home theater.

How Can I Tell If My Subwoofer Has A Problem?

How Can I Tell If My Subwoofer Has A Problem

Most people want to know how to tell if a subwoofer is defective. The answer is the exact same. Look for more bass, and the problem is in your amplifier.

A subwoofer can be built in a small space and still deliver great music.

The amplifier subwoofer woofers are usually located in the front.

The stereo system was designed to extract all of the music from the car. This means that the stereo can handle music with very low frequencies.

You will enjoy lower frequencies if you have a small enclosure installed in your car.

Make sure you choose a subwoofer with an enclosed enclosure when choosing one. This will ensure that the amplifier won’t produce low-frequency music.

The location should have an airflow rate that is less than the vehicle’s normal.

You should, however, make sure that the subwoofer woofer has a filter.

This is crucial because some people use direct impingement in their vehicles that removes all air and causes distortion in music.
