A blown subwoofer can be a massive headache for any home audio enthusiast. Not only will the lack of bass impact your listening experience, but it can also lead to potential damage to your speaker system. If you’re experiencing issues with your subwoofer, here are a few tips to help get it working again:
- Verify that the power is being sent to the subwoofer. Ensure all wires are plugged in correctly, and power comes from the wall outlet or battery pack.
- Check for loose connections between the woofer and amplifier. Push and pull on these connections until they’re solid, then try powering up the system again. If all else fails, you may need to replace your woofer assembly.
- Try swapping out different cables to find the culprit.
3 Main Signs of a Blown Subwoofer:
When it comes to electronics, many people are familiar with the term “blown capacitor.” But what about a blown subwoofer? Unfortunately, this common issue can lead to decreased performance and even damage your audio equipment.
So if you notice any of the following signs that your subwoofer may be blown, take action immediately:

Strange Noises:
Strange noises from your subwoofer could be a sign that it’s blown. Here are some things to check if you think your subwoofer is on its last legs:
- Ensure the amplifier is installed correctly and grounded – If you’re experiencing strange noises or loss of bass when the amplifier isn’t plugged in, there might be a ground issue. Ensure all wires are connected to the correct terminals on the amp and there’s no excess wire clutter around the woofer.
- Check for loose connections – Faulty wiring is another common cause of strange noises and poor bass response. Ensure all connections between the woofer and speaker are tight, ensuring not to omit any wire strands.
Damaged Cone:
If you notice that your subwoofer has a damaged cone, the speaker has likely been blown. This is a common issue with subwoofers and can be caused by various factors. If the cone is severely damaged, it may not be able to reproduce low frequencies accurately, resulting in a distorted audio output.
Sometimes, the cone may fall off entirely, rendering the subwoofer useless. If you notice any signs of damage to your subwoofer’s cone, consult a professional technician immediately to ensure accurate sound reproduction and long-term reliability.
Resistance of the Voice Coils:
As the voice coils heat up, they may resist movement or coil resistance. This coil resistance usually indicates that the subwoofer has blown its speaker amp and needs to be replaced. Coil Resistance can be determined by taking an ohm reading of each voice coil at one end of the subwoofer enclosure and noting the average value. The higher the coil resistance, the more likely it is that your speaker amp has blown.
Some main reasons for Blown Subwoofer:
These were a few signs that would tell whether the subwoofer is working; let’s now see why the subwoofer could’ve blown out so that we can prevent these in the future.
High Voltage & Power:
A high-voltage power supply (HVP) is one of the leading causes of blown subwoofers. When a subwoofer is overloaded with too much power or an improper power supply, the electrical currents flowing through the amplifier and speaker can damage them. This can lead to a wholly blown amplifier and speaker in extreme cases.
Subwoofers use a small amount of power to produce deep bass notes. When the amp powering a subwoofer is overloaded, it may start to heat up and eventually blow. Overloading can also be caused by using an HVP that cannot deliver the necessary power to the subwoofer. If your HVP doesn’t have enough juice, you’ll see distortion in your audio signals and excessive heat buildup on the amplifier and speaker.
Short Circuit:
For a subwoofer to produce bass, it needs a continuous power flow. When there is a short circuit in the system, this power flow is interrupted, and the subwoofer can’t produce the deep bass tones we’re used to hearing. Short-circuiting also damages the speaker’s coil, which can cause it to fail prematurely.
So if you’re noticing your subwoofer isn’t producing as much bass as it used to, there’s a good chance it’s due to a short circuit. And if you’re having trouble getting your speakers repaired or replaced because of this problem, make sure to have them checked out by a professional.
Internal Failures:
Internal failures are the main reason why subwoofers blow. Nearly two-thirds of all blown subwoofers can be attributed to defective internal components. This includes broken or loose coils, bad bearings, and overheating amplifiers.
When these problems occur, the vibrations produced by the bass frequencies get trapped inside the subwoofer and can eventually cause it to fail. This is why it’s essential to inspect your subwoofer regularly for signs of wear and tear and replace any components that fail.
What to do with Brown Subwoofer?
If you’re like most people, your brown subwoofer has been collecting dust in the corner of your room. You may have tried to use it, but it’s not up to par. There are plenty of things you could do with your brown subwoofer, but here are a few ideas that might help get it back into action:
- Use it as a bass boost for your stereo system. Add it to a speaker set-up that is already a complete blast, and see how much more depth and power you can get from your music.
- Mount it on the wall next to your television so you can enjoy the sound without having to strain to hear over the din of the TV show or movie playing. This is especially handy if you have a large living room with a lot of furniture between the TV and the subwoofer.
Conclusion:
The Brown Subwoofer is an excellent addition to any home audio system. It’s affordable, powerful, and easy to use, making it an excellent choice for anyone looking for a subwoofer. The Brown is worth considering if you’re looking for a new subwoofer.
Frequently Ask Questions (FAQs)
What to do if your subwoofer has blown?
If your subwoofer has blown, there are a few things you can do to fix it. You may need to replace the entire unit or just the speaker. If only the speaker is blown, you can replace the cone assembly.
What sound will the blown subwoofer make?
A deep bass sound is lower than what you would get from an average speaker. This can be helpful when adding depth to your music or creating an immersive listening experience. A high-pitched squeal or “ping” when the air pressure gets too high inside the speaker enclosure. This sound is typically only heard with high-power subwoofers and can be annoying if it’s constantly happening.
