JBL Charge 4 Passive Bass Radiators Replacement

Introduction

The passive bass radiators significantly help to improve the sound quality of the JBL Charge 4 by amplifying the deep pitches in sound. They also keep the speaker waterproof by sealing out water from the sides. This guide will show you how to replace the bass radiators if the bass of your speaker is not sounding as good as it once was, or if you need to gain access to the inside of the speaker.
