JBL Charge 3 Bass Boost

You can increase the low sounds output of this speaker by turning on and off the JBL Charge 3 bass boost mode. When ON, bass boost makes the passive bass radiators on the ends of the speaker vibrate a lot more. Furthermore, it adds a notable rumble quality to the playing program.

How to Turn Off JBL Charge 3 Bass Boost

By default, this speaker  has bass boost turned ON after a reset.  This adds a bit of extra treble in addition to lots more bass to the audio output as compared to when this feature is OFF.
