If your speaker is producing distorted or muffled sound, the issue may lie with the driver. The good news is that in many cases, a damaged speaker driver can be repaired. Here’s what you need to know:
Identifying the Problem
The first step is to determine which driver is causing the issue. If you notice a problem in one speaker, switch the left and right speaker wires to see if the issue follows the wire. This will help you identify which speaker is at fault.
Once you’ve identified the problematic speaker, remove the grille and take a closer look at the driver. If it appears to be making a rattling or rubbing noise, the voice coil may be the culprit. You can try gently pushing the cone in and out to see if it’s rubbing against the magnet.
Repairing Small Cone Damage
If you notice small holes or tears in the cone, you may be able to repair them using rubber cement or a speaker repair kit. First, unfasten the driver by removing the screws around the perimeter. Then, apply rubber cement to the front and back of any holes or tears, being careful not to use too much. If necessary, place a thin piece of kraft paper over the first layer of cement to prevent further tearing.
Replacing the Driver
If the driver is severely damaged, with large tears or holes, it may need to be replaced or re-coned by a professional. To replace the driver, first disconnect the wires from the back, being careful to note their positions. Then, remove the driver from the cabinet and measure its diameter precisely.
When selecting a replacement driver, make sure it matches the original in size and specifications. You’ll also need to ensure that it’s compatible with your speaker’s crossover network. Once you have the new driver, simply reverse the removal process to install it.
With some basic tools and a little patience, you can often repair a damaged speaker driver and restore your audio system to its former glory. However, if the damage is too severe or you’re unsure of the process, it’s always best to consult with a professional speaker repair technician.
