Introduction
If your Casio CTK keyboard (model 3200) has speakers that are distorted or broken, use this guide to replace them.
The speakers are an important part of the Casio keyboards, providing the sound from which you are able to make music. They are found behind a black plastic protector on the far right and left of the keyboard.
Determining if the speakers are playing correctly is pretty simple, make sure the volume is turned up and listen closely to one or both speakers to see if they are emitting the same or any sound.
This guide does require soldering, which can be a difficult and dangerous task for some. Here is a guide on how to solder safely.
