Your speaker can be blown for several reasons. Such as; electrical failure, playing it with full volume for a long time, constant overpowering, and many more reasons that could blow a speaker.

I know, speakers are very close to our hearts. We often refresh our minds with some fresh music. Speakers help us to do so. But if you have a blown speaker then it could destroy your mood by its hissing or scratching sound.

However, nothing is impossible in this world. So, if your speaker has blown recently. Then you don’t need to worry at all.  I will try my best to give some of the best solutions regarding our title “How to Fix a Blown Speaker”.

Indications of Having a Blown Speaker

I think we can easily understand if we have a blown speaker. As I have mentioned in the opening section, a blown speaker will produce an unpleasant and scratchy sound when you try to play it.

However, not all the time it will make scratchy sounds. Sometimes it will not produce any sound because of the blown speaker. I know it is quite an unusual thing you could ever face before a party.

Before repairing anything you must have clear knowledge about why this problem is occurring. How much depth you have reached in your problem? The solution will become too easier for you.

To eliminate half of the problem regarding blown speakers. I am going to discuss some indications that will help you to know if you have a broken speaker.

Sound Disruption

The clean and clear indication of the blown speaker is sound disruption. Your speaker will make some kind of fuzzy or hissy sound. It could occur because of the vandalized voice coil.

The sound disruption of a speaker is quite annoying. It can affect your mood easily. But as it is an electronic device you should better be prepared for this kind of unwanted situation.

Vibration Deficit

Vibration is normal when putting the hand on top of a completely functioning speaker. For woofers and subwoofers, this is very real. This results in greater vibrations on your speaker by turning up the volume on your radio.

One argument that might have blown out your speeches is that no noises exist, in particular at higher volumes. The downside is that it only fits on bigger speakers. Checking your palm for vibration will not work correctly if you have a comparatively smaller speaker system.

If a speaker bursts out, it’s possible that the cone is loosened out. When the speaker is broken entirely, the sound it once did could fail when it was brand new.

Infinite Resistance

There is one easy way to find your speaker’s condition. The way is to check the electrical response with the help of a multimeter. The multimeter will clarify whether your voice coil is ok or not.

For a speaker that functions normally, it should be graded as ohm on the computer. But the observed resistance is practically infinite for a blown-out speaker. If your speaker reads 2 ohms, as opposed to 4 ohms at which he is classified, he will also be blown.

So, these are the most common symptoms or signs that can give you a warning that you have a blown speaker.

Why Do Speakers Get Blown?

As I have mentioned earlier, Speaker gets blown for several reasons. From the research and practical experience, I have identified some of the major sources that can be responsible for the blown speaker. I am going to share it with you. That could become helpful for those. Who is really struggling with this issue?

Failures in Subwoofers

Subwoofers are designed to bring out low-pitch sounds. There are two kinds of subwoofers one is active and the other one is passive. Passive subwoofers basically is the speaker itself. It also contains a crossover. On the other hand, Active subwoofers are automated as well as it contains its own amplifier.

Subwoofer fails are triggered either by power distribution problems of Electrical or Mechanical. As the subwoofers are exposed to a lot of power, the electrical malfunction causes the voice belt to burn; this may arise from excessive gain or wired subwoofers, allowing the amplifier to lower its impedance.

Failures in Tweeters

Normally tweeters are speakers that repeat the sound at higher frequencies. Tweeters can produce sound between 3 kHz to 20 kHz. However, a human ear’s sensitivity will select between 20Hz and 20 kHz.

The Electrical or Mechanical power control problems contribute to faults in tweeters, midrange, and midbass speakers. Many failures happen because of Electrical loss because the speaker’s voice coil has so much power. Constantly unnecessary power results in burned voice coils.

How to Fix a Blown Speaker
