Use the JIS #00 screwdriver to remove the 3/32" screws that secure the speaker to the body.

Remove the smaller 3/32" screws that secure the left side of the speaker with a JIS #1 screwdriver.

The smaller screws are still the same length, but they have smaller screw heads. You can use the same screwdriver for both.

Using a Magnetic Mat throughout this process will help prevent losing screws.
