How To Check If a Subwoofer is Blown

Trying to figure out if you’re subwoofer is blown can be very frustrating.

There are no clear signs that indicate if it is, and you might just be hearing the difference in sound levels that exist between different audio sources.

A blown subwoofer can make your audio system sound terrible, and it’s important to know if it’s blown because repairing a subwoofer can be very costly.

Test The Subwoofer For a Blown Coil

It’s important to know the difference between a damaged voice coil and a blown speaker cone.

If your subwoofer is producing less bass than usual, you will need to identify the issue.

A voice coil is a piece of wire that attaches to the speaker cone and amplifies the current that runs to the speaker.

This simple device is what makes your music sound great. The wire can be made from a variety of materials including copper, aluminum, silver, or gold.

These coils have two terminals, positive and negative, which are connected to an amplifier.

To test whether a voice coil is blown, obtain a multimeter, which you can use to test the amount of voltage, resistance, and current.

Using the multimeter is quite simple. Attach the negative and positive probes of the multimeter to the negative and positive terminals of the voice coil of your subwoofer.

Then turn on the multimeter to see the resistance.

Result #1: If your reading is above 1.0 ohm, everything should be fine with your coils. The problem may be with the things connected to the coil.

Result #2: If there is no resistance at all, it means your voice coils are damaged.

Result #3: If the reading goes all haywire, it’s often a sign that your voice coil is busted. It’s not an exaggeration to say it’s a strong indicator that you’ve blown your voice coil.

Check If a Subwoofer is Blown

Test the Cone of Your Subwoofer

Place your hands on the subwoofer casing and slowly pivot until you can see the cone under it.

Gently push on either side of the cone to see if it moves.

Subwoofers are built with suspension systems to make sure the cone bounces back again after it moves.

If your subwoofer cone isn’t moving, something might be wrong with the parts of your subwoofer.

Test the Sound of Your Subwoofer

Many people don’t know that they can recognize the sound of their subwoofer just by listening.

It’s not possible to simply hear the sound and be able to tell if it sounds good or not, but it doesn’t mean you can’t test it.

The best way to test your subwoofer is to play a bass-heavy song and see how the bass sounds.

A subwoofer is a type of speaker designed to produce low-pitched audio frequencies. If you have a good subwoofer, the music will sound as if it’s coming from deep within your body.

We have made a list of great bass songs to test the quality of your subwoofer.

Just turn on your subwoofer and play any of the tracks we listed in the article with a low volume. If you heard a sound but it is distorted, then it simply means that your subwoofer is damaged.

If the sound of your subwoofer is only emitting a buzzing sound with the volume turned up high, it’s likely that your subwoofer has stopped working. Yes, it is probably completely blown.
