What happens when a subwoofer blows?
When a subwoofer blows, it typically indicates that the speaker has suffered a failure of some kind. Depending on the cause, the speaker may have literally blown apart, or its necessary components may have failed to operate.
It’s usually easy to tell if a subwoofer has blown — you’ll hear a loud, popping sound and then no sound. Possible causes of subwoofer failure include too much power, an excessive amount of excursion, incorrect impedances, and using too much low-frequency boost on the amplifier/receiver.
In some cases, a burnt voice coil is the cause, which results from too much power or prolonged high wattage. The damage can be permanent, or temporary — sometimes it’s easier and more cost-effective to replace the speaker than to diagnose and fix the underlying problem.
How can I test my subwoofer without a receiver?
Testing your subwoofer without a receiver is possible, but it will require a bit of extra work. First, you’ll need to connect the subwoofer to an amplifier that can run it. You can use a car amplifier, computer amplifier, or any other amplifier that can drive your subwoofer.
Once you have the subwoofer connected to the amplifier, you’ll need to create a test signal you can use. The easiest way to do this is to download a test signal generator on your smartphone or laptop.
You can then connect that device to your amplifier and send it to your subwoofer. When you play the test signal, you should be able to check the output of the subwoofer and ensure it’s working correctly.
If you don’t have access to a test signal generator, you can also use music as a way to test the subwoofer. Simply play some bass-heavy music, and keep an eye on the subwoofer. It should move accordingly, and you can tell if it’s working properly by the sound output and movement.
How do you test subs?
Testing subs is an important part of the process of making sure that the system is working properly. Depending on what type of sub is being tested, different test methods will be employed. Generally, tests will be designed to determine the performance of the subwoofers in terms of maximum SPL, frequency response and distortion.
Subwoofer performance tests involve the use of an audio analyzer. Generally, sweeps of specific frequencies and tones will be used to test the response of the sub, and the frequency range is typically from 20 to 200 Hertz.
While the sweep is running, the analyser will measure the maximum SPL of the sub, as well as any distortion. Additionally, it will be able to measure the use of the driver and give a reading of what the range of the subwoofer is.
The second group of tests that can be done with a subwoofer is subjective testing. This type of testing requires listening to the sub in operation. It is typically done in an environment with no external noise and will involve the use of an SPL meter so the engineer can monitor the maximum levels during the test.
Music or tones should be played at wide range of frequencies and at a variety of volumes so the engineer can ensure that the subwoofer is properly reproducing sound at all levels.
Overall, testing subs is an important part of the process of making sure that a system is working properly. In order to do this properly, audio analysis should be used as well as listening tests to ensure that the subwoofer is meeting the desired specifications.
How do I use a multimeter to check a subwoofer?
To check a subwoofer with a multimeter, you should first make sure that the multimeter is on the correct setting. It should be set to measure DC volts. Once the multimeter is set, plug the leads into the terminals on the subwoofer.
You should then make sure that the power switch is in the “on” position. Now, press the “test” button on the multimeter and if you get a reading in the vicinity of 12V (or battery voltage, if the subwoofer is battery powered) then the power is being supplied to the subwoofer.
To check the output of the subwoofer, you should change the setting of the multimeter. This time it should be set to measure DC current, and then you should place the leads into the terminals on the subwoofer again.
Keep the power switch in the “on” position, and press the “test” button. You should get a reading in the vicinity of 1A or more, indicating that the subwoofer is receiving power and producing sound. If you do not get any reading, check the wiring and the power source.
If all these steps have been followed and there is still no reading, then the subwoofer might have a problem and might need to be serviced.
How do you know when a subwoofer is bad?
Knowing when a subwoofer is bad usually takes some knowledge of the normal characteristics of a functioning subwoofer. Some of the common signs that might indicate a bad subwoofer include unusually weak or distorted sound, no sound at all, hum or buzzing, rattling or distorted vibration, or a visual inspection revealing signs of corrosion or physical damage.
If the subwoofer is producing sound but has a distorted or low-quality tone, it could be a sign of a worn-out driver or some wiring issue with the connections. If it is completely silent, the problem could be more serious and the subwoofer would need to be checked for loose connections, blown speaker, blown fuse, or a burnt-out amplifier.
If a buzzing or humming sound is heard even when the volume is turned off, it could be related to wiring interference or a problem with the amplifier or speaker. Visually inspecting the subwoofer can also give clues that it is damaged, such as cracks in the cone, corrosion, or loose pieces of material inside.
If any of these problems are present, it is likely a sign that the subwoofer is bad and should be replaced or repaired as needed.

Also ensure the cables are not kinked or damaged in any way.
If the cables and power supply are ruled out, the issue might be related to the receiver. Check the receiver to make sure it is powered on and the receiver output settings are set correctly. Subwoofer settings are typically accessed through the receiver or amplifier, and should be set to “On” or “Yes”.
If none of these potential fixes have worked, the issue is likely due to a system or driver problem. Check to see if the subwoofer drivers are working properly, as these can often malfunction and need to be replaced.
If the issue is still not resolved, consider consulting a professional technician to inspect the system and provide further diagnosis.
Why is there no sound coming from my subwoofer?
The most likely explanation for why there is no sound coming from your subwoofer is that either the power connection is not complete or the speaker/cable connection may not be correctly connected.
To troubleshoot this issue, start by verifying the power connection from the subwoofer to a power source is secure. Additionally, check the connection from the wall outlet to the power source. Also, check the connection from the sound source to the subwoofer.
Make sure that the speaker wire and the connection from the sound source are properly connected. If there is no connection, then the sound cannot be transmitted, resulting in no sound.
If all of the connections are properly connected and the power is on, then the subwoofer likely has a technical issue. You could try disconnecting and reconnecting the speaker cables or power cable to the subwoofer, then see if the sound comes back.
If not, then the subwoofer will need to be serviced or replaced.
How long does a subwoofer last?
The duration of a subwoofer’s life depends on a variety of factors, including the quality of the subwoofer itself, how often it is used, and the type of environment in which it is stored and operated.
Generally speaking, a high-quality subwoofer can last anywhere from five to 10 years if it is regularly maintained and stored in a clean and dry environment. In contrast, a lower quality subwoofer may last only several years at best due to poor construction, low-quality materials, and inadequate weatherproofing.
Regular maintenance and cleaning of the interior and exterior components of a subwoofer can help ensure a longer life span. Additionally, proper storage of the subwoofer in an appropriate environment free of high temperatures, dust and moisture can also help extend the life of your subwoofer.
Do subwoofers wear out?
Yes, subwoofers do wear out over time. The moving parts of the subwoofer, such as the speaker cone, can begin to wear down and lose their integrity with prolonged use. The subwoofer’s driver can also start to degrade, causing a reduction in sound quality.
Additionally, the amplifier can start to show signs of wear due to overuse or aging. To ensure that your subwoofer is in tip-top condition, it’s important to regularly check and maintain it. This can include cleaning the driver and checking the connections between the amp and subwoofer.
While subwoofers can wear out, they’re generally built to last. With proper care and maintenance, your subwoofer can provide years of reliable service.
How do you diagnose sub not working?
Diagnosing sub not working can be challenging, as there are a number of potential issues that could be causing the problem. The first step in diagnosing a subwoofer that is not working is to inspect all connections between the subwoofer and the audio receiver, making sure all connections are securely in place and no cables have become disconnected.
It’s also important to make sure that the volume levels and crossover settings for the subwoofer are properly adjusted on the receiver.
Additionally, if the subwoofer is connected using a wireless signal, it’s important to make sure the wireless transmitter is correctly configured and that no interference is present. This may require moving the subwoofer or the transmitter to a different location.
Once all connections have been verified and any wireless issues have been addressed, it’s important to check the balance settings of the sound system. If the surround sound system is configured in stereo mode, then these settings should be adjusted until the subwoofer is properly balanced with the other speakers.
If the subwoofer is part of a surround sound system, then the balance settings should be adjusted until the subwoofer can be heard with every audio channel.
If the subwoofer still appears to not be working correctly, then the issue may be with the subwoofer itself. If that is the case, then it’s important to verify the speaker is still properly connected to the amplifier, and there are no loose or damaged wires.
Additionally, if the subwoofer has an integrated amplifier, then any issues related to the amplifier should be inspected, such as checking the fuse, power cables, and the voltage running through the amplifier.
Any issues discovered with the amplifier should be addressed accordingly.
Finally, if all else fails, then the subwoofer may need to be repaired or replaced entirely in order to get it working again.
Where is the fuse in a subwoofer?
The fuse in a subwoofer is typically located near the power source and/or amplifier. Depending on the model of subwoofer, it can be located either inside the cabinet or on the back of the subwoofer. If it is inside the subwoofer cabinet, it may be best to consult the user manual or contact the manufacturer to find out exactly where it is located.
Typically, the fuse will be found at the point where power is connected to the subwoofer, so it makes sense to start by checking both the power source and amplifier connection points. It may help to unscrew the back panel and use a flashlight to locate the fuse.
If the fuse is not visible, it may be best to assume that it is located inside the subwoofer cabinet and seek assistance from the manufacturer if necessary.
