It is not uncommon for a subwoofer to make noise when it is turned on. In fact, this is usually just the sound of the subwoofer’s internal amplifier warming up. However, there are some cases where this noise can be indicative of a problem with the subwoofer. In this article, we will explore some of the possible causes of a noisy subwoofer and how to fix them.
What are the causes of the noises?
The most common causes of noise from a subwoofer are a loose connection, a damaged terminal, a problem with the subwoofer’s internal amplifier, a ground loop, or a defective voice coil. One of the ways to figure out what is wrong with a subwoofer might be determining the noise.
Can I say what the problem is if the subwoofer is humming/buzzing/etc?
If the subwoofer is making a rattling noise, it could be caused by a loose screw or bolt. Tightening the screws or bolts should stop the noise. If the rattling noise persists, it could be indicative of a more serious problem, such as a cracked speaker cone. In this case, the subwoofer will need a replacement.
If the subwoofer is making a popping or clicking noise, the reason could be a problem with the subwoofer’s crossover. The crossover is responsible for filtering out frequencies that the subwoofer cannot reproduce. This can be fixed by replacing the crossover or having it repaired by a qualified technician.
In some cases, a subwoofer may make a humming noise when it is turned on. This is usually caused by a problem with the AC power supply. If the subwoofer is plugged into a surge protector, try plugging it directly into the wall outlet. If this does not fix the problem, the subwoofer may need to be replaced.
If the subwoofer is making a buzzing noise, you will probably have to deal with a subwoofer’s voice coil. The voice coil is responsible for converting electrical energy into sound waves and can cause a buzzing noise if being damaged.
If the subwoofer is making a hissing noise, it could be caused by a problem with the subwoofer’s enclosure. If the enclosure is not sealed properly, air can leak out and cause the subwoofer to make a hissing noise. This can be fixed by sealing the enclosure or replacing it.
If the subwoofer is making a thumping noise, it could be a sign of a problem with the subwoofer’s suspension. The suspension is responsible for absorbing and dispersing the energy from the subwoofer’s bass output. You can replace the suspension by yourself or ask for professional help.
No matter what type of noise your subwoofer is making, you better have it checked out by a qualified technician. They will be able to diagnose the problem and recommend the best course of action, a replacement or a simple repair.
