How to Bass Boost JBL Boombox BT Speaker

You can change how loud the bass is on the JBL Boombox, by turning on and off its bass boost mode. When switched on, this mode makes the passive bass radiators on the left and right edges of the speaker vibrate much more. Plus, this adds a low rumble quality to the playing program, that travels pretty far from the speaker.  So, for you boom lovers, this post shows how to bass boost this speaker, to get that extra kick.





How to Turn Off Bass Boost on the JBL Boombox Speaker

By default, the Boombox has bass boost mode turned ON after a reset.  This adds a bit of treble and lots of extra bass to the audio output as compared to when this mode is OFF.

You can turn this extra bass mode off by pressing and holding in the Volume Down (-) and Bluetooth buttons as circled in green in the last picture above, for about ten seconds, until the Power and Connect Plus buttons both light briefly.  See these lamps pointed out in the next picture.

How to Turn On Bass Boost on the JBL Boombox Speaker

To activate bass boost once again, press and hold the Volume Down and Bluetooth buttons in until the Power and Connect Plus buttons light white.  Then release the buttons.  When the buttons inside the oval above both light for a second or two and then go off, bass boost has resumed once again.

Warning

The drivers really thump when you switch ON bass boost.  So take care in how loudly you play this speaker with the bass boosted, to avoid damage to the speaker drivers. If the bass is crackling, tapping, or otherwise distorting, turn it down !
