JBL Boombox 2 Low Frequency Mode Explained

You can change how loud the bass is on the JBL Boombox 2 speaker, by turning on and off its low frequency mode. When switched on, this mode makes the side mounted passive bass radiators vibrate much more.  Plus it adds a low rumble quality to the playing program, that travels pretty far from the speaker, even when outdoors.





How to Turn Off JBL Boombox 2 Low Frequency Mode

By default, the JBL Boombox 2 has its bass 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 low frequency mode is OFF. In this demo, we use a Boombox 1.  But we will update the pictures as soon as we acquire a Boombox 2.  At any rate, the procedures for the speakers appear to be the same.

You can turn this low frequency mode off by pressing and holding in the Volume Down (-) and Bluetooth buttons for about ten seconds, until the Power and Connect buttons light up together, as shown in the next picture, pointed at by the green arrows.  Find all these buttons on the top of the unit, as shown in the picture above.

How to Turn On JBL Boombox 2 Low Frequency Mode

To turn low frequency mode back on, again, then again, press and hold the Volume Down and Bluetooth buttons in until the Power and Connect buttons light up.  Then release the buttons.  When the buttons inside the oval island on the speaker light up, the low frequency mode resumes once more.

Warning

The drivers really rock when you switch on low frequency mode.  So be careful with how loudly you play this speaker with the low frequency mode ON, to avoid damage to the speaker drivers inside. Certainly if the bass is crackling, tapping, or otherwise distorting, turn it down !
