How To Fix A Subwoofer With No Sound

How To Fix A Subwoofer With No Sound?

When a subwoofer is damaged, it indicates that the power is either too high or too low. Better construction allows for more errors, which means the speaker will survive longer.

Overpowering a speaker can damage the voice coil by causing it to move too far and crash on the speaker’s plate. Also, when music is playing, you may hear a buzzing sound, indicating that the subwoofer is damaged.

Overheating, ripping from erratic signals, and jamming the voice coil can all be caused by underpowering a speaker. The best amplifier is one that is rated for the RMS of your speakers.

Damage can be caused by having too little or too much power. Do not increase the volume if you hear a distorted signal or sound.

Checking For A Damaged Subwoofer

Checking For A Damaged Subwoofer

There may be some tearing or voice coil difficulties with damaged subwoofers. First, check whether a speaker stops working to see if the issue is with the speaker rather than the subwoofer. If the problem persists, It must replace the speaker.

There may be some ripping or voice coil difficulties with damaged subwoofers. Because of two factors, these are more complex problems to solve:

  • Damage Coil: The voice coil is the element that receives power to assist it in pulling and pushing against the loudspeaker pole. It raises and lowers the speaker cone to make a sound in an author’s speakers.

If you’re not confident if the coil is destroyed, connect the coil’s terminals to a multimeter and see if there’s no resistance. If there isn’t, the loop is probably ruined.

  • Speaker Cone Damage: It’s simple to spot a damaged speaker cone. The voice coil may be jammed or broken if the cone is inflexible and does not move. A minor rip in the foam suspension can potentially cause issues with the speakers on your subwoofer. Look for minor tears or holes with a magnifying glass.

The next step is to decide whether or not to repair a tear in the subwoofer cone or foam. It should take around 30 minutes to replace the foam, and the parts are readily available. If any cones, spiders, or voice coils are broken, they must all be replaced.
