Locate the seven 11mm screws on the back of the keyboard in order to remove the speaker from the front of the keyboard.

There are 7 screws that need to be removed in total to replace one speaker. Use a JIS-1 screwdriver to remove these screws: 2 on the back panel, and 4 on the side of the keyboard.

Three of these seven screws are slightly hidden and may be hard to find.
