Take a closer look at the vent or grille on the subwoofer. If it’s moving or pulsing when music or audio is playing, it’s a sign that the subwoofer is producing sound waves.
Auditory Checks
Visual inspections are just the beginning. To get a better sense of whether your subwoofer is working, it’s time to conduct some auditory checks.
Listen For Low-End Response
Play some music or audio with deep bass notes, such as electronic dance music or a movie with a lot of explosions. If you can feel the bass rumbling through the floor or your seat, it’s a good sign that the subwoofer is working.
Compare Sound With And Without The Subwoofer
Turn off the subwoofer and play the same music or audio. Then, turn it back on and compare the sound. If the sound is significantly better with the subwoofer on, it’s likely working properly.
Technical Checks
If you’re still unsure about your subwoofer’s performance, it’s time to get technical.
Check The Settings
Ensure that the subwoofer is set to the correct input and that the crossover frequency is set correctly. The crossover frequency is the point at which the subwoofer takes over from the main speakers, typically around 80-120 Hz.
Use A Sound Pressure Level Meter
A sound pressure level meter can help you measure the sound output of your subwoofer. These meters can be purchased online or rented from audio equipment suppliers.
Check The Amplifier Or Receiver Settings
Verify that the amplifier or receiver is set to output audio to the subwoofer channel. Also, check the settings for the subwoofer’s low-pass filter, which determines the frequency range that the subwoofer receives.
Troubleshooting Common Issues
If you’ve conducted all the above checks and your subwoofer still doesn’t seem to be working, here are some common issues to troubleshoot:
No Power
- Check the power cord and make sure it’s securely plugged in
- Verify that the outlet is working by plugging in another device
