Introduction
If your speaker does not sound right, it may be time to replace the passive radiator. The following guide will show you how to replace the passive radiator in the Logitech UE MegaBoom 3. A passive radiator moves back and forth to create sound thanks to the fluctuations in air pressure within an enclosure based on its resonant frequency. If your device is still loud but the sound and the bass is off the issue is most likely your passive radiator and not the speakers.
Before starting this guide make sure you turn your speaker off and on and test the sound again just incase the frequency issue was not a one time thing. If the frequency is still off you will need to complete this guide.
This is a difficult guide to complete so be sure to read the entire guide thoroughly before starting.
