Now you are getting skeptical if the subwoofer is blown-out or it just doesn't sound good.
When your subwoofer is blown out, you volition unremarkably hear incredibly distorted sounds, and your overall feel will be destroyed.
Don't worry; in this weblog, I'll show you how to test your subwoofer so yous tin rest bodacious that information technology's working properly.

Because your subwoofers create noise, it's like shooting fish in a barrel to know if they're working. Every bit a result, at that place are no issues if the audio is being produced.
Still, things aren't equally simple as they appear.
Information technology's possible that sounds are withal coming from your subwoofer, just that doesn't guarantee it's functioning properly.
It may create undesirable frequencies in the subwoofer's intended range, such as fuzziness or baloney.
This means that the subwoofers accept a specific frequency and must emit an aural sound so that you tin can find if they're working properly.
How to notice that the subwoofer is blown-out?
We'll demand to listen closely to check if the subwoofer is blown out now that yous've made sure information technology'due south non broken.
When the sounds are distorted or break in between frequencies, you know your subwoofer is blown.
Autonomously from that, if the sound quality of your subwoofer begins to deteriorate, it is possible that information technology has blown out.
Withal, y'all tin can't determine if it'south blown out or has other problems only by listening to it.

How to Test Subwoofer
There are two ways of testing your subwoofer, one would be with a multimeter and the other i would exist without Amp.
Multimeter Method and Subwoofer's Vocalization Coil
The simplest and about pop way is to use a multimeter.
A multimeter is a device that measures electric current, voltage, and, in near cases, resistance over a broad range of values.
You'll be able to check the vox coil resistance this manner(the vocalisation whorl is fixed on positive and negative terminals), which is basically what informs you lot if the subwoofer has diddled out.
- First thing commencement: plow off the subwoofer and remove it from the power source.
- The side by side step is to simply disconnect it from any wires or connections that it is connected to or that environment information technology.
- The next pace would be to locate your subwoofer'due south voice gyre. There are various subwoofers, each with its own method of the voice coil.
- After you lot've gotten your hands on the vox coil, connect information technology to the multimeter. Brand sure you connect to a positive terminal.
- In the end, with your multimeter turned on, you should be able to view the resistance of your subwoofer.
You will be able to tell the consequence in this way.
If your multimeter shows 1 ohm or greater as resistance, it'south likely that your subwoofer isn't blown out.
The voice coils, on the other hand, are harmed if in that location is no resistance in the multimeter.
Worse, if it shifts noticeably, it implies that they are diddled and information technology's fourth dimension for you to get a new subwoofer.
Without Amp Method
While using an external amp to examination the subwoofer is straightforward, information technology helps you to spot faults and which frequencies are faulty.
The trick is to effigy out how to test it without an amp, which is a lilliputian tricky.
Get the necessary tools earlier you start testing it.
A 9V battery, a tester, and a wire are all you'll demand.
- Like always make certain you have the subwoofer unplugged from the power source.
- Y'all tin can begin past connecting the battery to the subwoofer now that you take the necessary hardware.
- To do so, have the wire and connect the positive final of the coil to the positive last of the battery.
- After yous've finished connecting the battery, check to see if the cone is rising. Equally soon as you connect information technology, it should rising, if the subwoofer is operating properly that'due south it.
If at that place is no movement, it suggests that the subwoofer has blown out, and y'all can check this by repeating the first step with the tester or multimeter.
What Can Crusade a Blown-Out Subwoofer?
Excessive or too much power is one of the almost common reasons for a diddled subwoofer.
By sending too much signal to the subwoofer and having information technology play music at high volumes all the time, the subwoofer gets "stressed", and the vocalism coil gets damaged as a result.
The failure of speakers is caused by a damaged and overheated voice whorl.
Once the subwoofer is blown, it'due south fourth dimension to shop for a new one. Trying to get it to work again or sending it to different mechanics is pointless. You're wasting both time and coin.
Last Words
I attempted to teach yous how to examination your subwoofer in the most basic and preferable manner.
At that place are professionals who audit subwoofers in a variety of means, but those are the most common ways and the ones that are proven to work.
Hopefully, I was clear and y'all were able to gain some do good from this weblog.
I don't want you to waste your cash on a mechanic. Instead, you lot might use that money to buy a new subwoofer if your existing i is blown out.
This brings everything to a close. Accept care and have fun until adjacent fourth dimension.
