How to Repair a Damaged Loudspeaker

Loudspeakers can break if being abused. In most cases, a loudspeaker will get damaged if you drive too much wattage into it. This can easily happen if you disconnect or connect audio cables audio amplifier while the amplifier is turned on. Reconnecting a cable can easily create loud plops which can blow a speaker diaphragm. Additionally, speakers can easily get damaged if they fall down because you trip over speaker cables and accidentally pulled the speakers off their stand.

Obviously, you should take some precautions against damaging your speakers. When making the speaker cable connections, don’t leave cable dangling around which can become a trip hazard. Also, mount the speaker firmly onto a stand. Ideally, use fasteners that will prevent the speaker from being pulled off the stand.

When connecting a speaker, never turn your amplifier to maximum. Rather, turn the amplifier to a low setting and then gradually increase volume. This will prevent the speakers from blowing because you are hitting them with too much wattage. Also, always turn the amplifier off when disconnecting or reconnecting audio cables.

If you do damage to the speaker then investigate where the damage has occurred. If the speaker itself still has sound but the enclosure is cracked then you can apply some adhesive to the crack in order to fix the problem. However, if you have blown a speaker transducer then the problem is more serious. You will need to replace that transducer. First of all, you will have to open the speaker enclosure. This might be quite tricky since some vendors will glue the enclosure together thus making it virtually impossible to open it.

You may need to use a saw in order to cut away the rear panel. Make sure that the cut is located next to the side wall. Next, unsold of the speaker cable which is connected with the transducer. Use a soldering iron it has a moderate temperature. Then remove any screws holding the translucent place. Once the transducer is out of the speaker, investigate exactly the size and specifications in order to purchase a replacement. You might want to take the transducer to your dealer will help you find a similar model.

Once you have picked out a replacement, it is time to reverse the above steps. Prior to removing the speaker cable, taken note of the polarity in order to make sure that the new transducer will be sold at with the same polarity. Then finally reassemble the rear panel.
