So, your subwoofer isn’t working and you’re not sure why? Is it sounding muffled or distorted? In this blog post, we will give you a few tips on how to tell if a subwoofer is blown and what to do if it is. Keep reading for more information.
What happens when a subwoofer blows?
When a subwoofer blows, it means that the voice coil has burned out. This can happen for a number of reasons, such as over-driving the subwoofer or running it at too high a volume for too long. When the voice coil burns out, it damages the speaker and it will no longer be able to produce sound.
How do I know if my subwoofer is blown?
If you’re not sure whether your subwoofer is blown, you can try some troubleshooting techniques.
One thing to check is the wiring. Make sure all the cables are plugged in correctly and that there is no damage to the wiring. If there is damage, you will need to replace the wiring.
Another thing to check is the speaker itself. Make sure that the speaker is properly mounted in the enclosure and that there is no harm to the speaker cone. If the cone is bowed out, discolored, or has burn marks on it, then the subwoofer is likely blown.
Then listen if the subwoofer isn’t producing any sound or you hear rattling or buzzing. If the sound is distorted or less powerful than usual, that’s a sign that the subwoofer is starting to fail. If there is a rattling noise coming from the subwoofer, that means the speaker cone has become detached and is no longer functioning properly. If there is no sound coming from the subwoofer at all, then it’s most likely completely blown. Not sure what a blown subwoofer sounds like? It’s best to take your speaker to a professional to have it checked.
Finally, you can check the amplifier for signs of burning or overheating. If the amplifier is hot to the touch, then it likely needs to be replaced. To confirm this, you can test the speaker by unplugging it from your amplifier and plugging it into another speaker. If you still hear the same symptoms, then the subwoofer is likely blown and you will need to replace it.
Can a blown subwoofer be fixed?
Mostly, no. In some cases, a blown subwoofer can be fixed. If the speaker is still intact, you might be able to fix it by replacing the fuse or the driver.
