Do you want a new pair of home audio speakers but can't afford to spend hundreds of dollars? Then why not repair an old speaker yourself for as little as $30!? Replacing a speaker driver is an easy process, whether you have a blown speaker that needs to be fixed or an older speaker that could use a boost in performance. This guide, perfect for DIY types, will look at the process of selecting an appropriate driver for your speaker, as well as the physical replacement. Armed with nothing more than a screwdriver (or drill) and ruler, this quick and straightforward process will have you upgrading your home stereo in no time!

Step 1: Find the Problematic Driver
Before you begin, you have to know which driver needs to be replaced. First, remove the cloth section covering the front of the speaker, more commonly known as the speaker grill. This should come off fairly easily.
To test the speaker, play music through it. Music is the ideal media to test with because more frequencies will be used simultaneously, allowing you to pinpoint the blown or under-performing driver more quickly. Based on what type of driver you are testing, you should adjust your system’s equalizer accordingly:
• Tweeter: Increase the system’s treble setting
• Mid-Range: Increase the system’s mid setting
• Woofer: Increase the system’s bass setting
Run each driver test individually at a reasonably high volume (somewhere around 7 or 8 out of 10) and take note of any noticeable cracking or buzzing. Based on this test decide which driver, or possibly drivers, need to be replaced.
Step 2: Unscrew the Old Driver
Unplug any wires coming into or out of the speaker to ensure that it is not hooked up to any sort of power source. Unscrew the guide screws holding the driver to the box. Hold onto the driver while removing the final screw to ensure it doesn’t fall.
