Step1
Disassemble the offending speaker carefully. If there is a metal faceplate on the speaker, use a screwdriver to remove it. If it is covered with any kind of fabric, gently loosen the seams without tearing.
Step2
Repair a tear in the cone of the speaker. If the cone of the speaker is punctured or torn you can use some tape or glue to repair the hole. If you are using glue you need to be sure the hole is completely covered.
Step3
Check to see if the voice coil is damaged. Look at the voice coil to see if it's melted at some point. A gap in the coil will cause no sound to flow or to be very distorted, depending on the size of the gap. If the voice coil has melted you will have to replace the speaker.
Step4
Order the replacement parts. You can order replacement parts directly from the manufacturer or from Web sites like US Speaker. Make sure you know the part number(s), which are usually located on the inside of the speaker or backside of the cone.
Step6
Once you have the replacement parts, carefully note how the damaged part is attached. Remove the part and install the new one in the same way. This may require a soldering iron to reattach wires.
Step7
Hook the speaker up and test it at low volume before your next party. If the speaker is still not working you need to verify that the replacement part was installed correctly. If you feel you replaced everything correctly it may be time to take the speaker to a professional.
