How to repair speakers?

How to repair speakers?

There are many ways to do it. The most popular and cheapest way is to buy a new speaker and install it in place of the old one. If you go on YouTube, you can find plenty of videos on how this can be done.

You will need a screwdriver set, solder gun, and soldering wire for this job. Of course, you can use a glue gun instead of a solder gun but keep in mind that if your speaker goes wrong again (it often happens with cheap models).

Replacing glued parts will be hard or even impossible without breaking some features, which may lead to the need for an entire replacement of the speaker unit for example, the plastic ring which holds screws.

The process is not complicated and a pretty fun project. The most challenging part is to disassemble the speaker without damaging it.

If you are good at soldering, another way to repair speakers is to replace coils with shorter ones. The following article describes the process, “How to fix speakers?”. It’s useful for low-frequency speakers, which are often damaged by longer tone wires that break coil continuity after some use.

However, the best solution would be the replacement of worn-out parts with new ones. This can be done using original spare parts for sure. But here comes a problem, because finding an owner of a local store who has this kind of spare part will hardly happen. So you will need to buy them online and wait for their delivery, which can take up to a few weeks. This is not the best option for speaker repair, but this may be your only chance if you lack the skills to do the job yourself.

If you still decide to buy original spare parts, make sure they are compatible with your model before spending money on them. 

Can you repair blown speakers?

It is possible in some cases. The best solution would be to replace the coils or whole speakers unit with the original spare part. This can be done using the old speaker as a donor, which will save you money. If the damage isn’t too extensive because replacing a single component might solve your problem without the need for the complete replacement of the speaker.

Another option is car audio speakers, which are usually designed to withstand high power to handle higher voltage than factory-installed ones without problems. However, when it comes to low-frequency woofers, this may not work correctly because impedance and other electrical characteristics are tuned to match the factory-installed amplifier output stage perfectly.

How do I know if my speakers are damaged?

The first symptom of speaker damage is usually distorted sound. If this happens, start checking connections and wiring to find a broken wire or another part that may be damaged in the process. Another common issue would be ground wire disconnection, which leads to complete sound loss even when all speakers are connected correctly.

The second symptom of speaker damage may occur after a long period of use when specific electrical components get worn out for example, voice coil. This may not happen during an average lifetime for car audio systems because they are designed to withstand strong vibrations. Still, when you install them into the home stereo cabinet with a low-frequency amplifier that can output a tremendous amount of power. You will need much higher quality speakers than factory-installed ones.

Bass speakers often get damaged when the bass amplifier sends a signal with higher power than speakers can handle. The same thing happens if you overdrive them by sending too high voltage to your speakers or simply disconnecting the speaker from the +12V source while music is playing.

Speakers fail in many different ways, and the most popular types of failures include blown tweeters, blown mid-range speakers, broken cabinets, and wholly forgotten drivers (woofers). When it comes to car audio systems, wiring problems are not common because they are designed to withstand rough conditions during transportation. Still, when you install a car audio woofer on an amplifier intended for home use, then there is a chance that the speaker will get burned out or even explode due to the tremendous amount of heat created by the voice coil.

What can damage a speaker?

Speakers are made from very thin and fragile material to get damaged easily. The most common causes of speaker damage include:

You are overdriving speakers by sending them strong signals with high power ratings for too long (for example, when playing music with bass boost). If you do not know how much power rating your amplifier has, simply never turn it up higher than half of its maximum rating. This will ensure that there is no way you can damage your speakers unless you try to. If possible, disconnect speakers when the volume is set at maximum because in some cases, even 10W RMS may be enough for complete replacement.

– Disconnecting +12V power wire while music is playing (any wire which goes into your speakers or amplifier). This may be caused by damaged wire or simply disconnecting the speaker from the power source (usually battery) to make a quick test.

Connecting speakers and amplifiers with the wrong polarity (check polarity markings on both speakers and amplifiers before making connections). The same thing applies when you mix positive and negative wires. This will cause severe damage to your speakers in any case, so please double-check polarity when making connections.
