JBL Xtreme 3 Low Frequency Mode, Extra Bass !

You can change how loud the bass is on the JBL Xtreme 3, by turning on and off its low frequency mode. When active, this super bass mode makes the passive bass radiators vibrate a great deal more. Plus, low frequency mode adds a deep rumble trait to the playing program.  Thus, this enhanced bass travels pretty far.

How to Turn Off JBL Xtreme 3 Low Frequency Mode

By default, the JBL Xtreme 3 has its bass mode turned ON after resetting.  This adds some treble and increased bass to the audio output as compared to when low frequency mode is OFF.  Also, the midrange levels sound like they drop a bit when low frequency mode is active.

You can turn this extra bass mode off by pressing and holding in the Volume Down (-) and Bluetooth buttons for about ten seconds, until the Power and Bluetooth buttons, and the oval that surrounds them, all light up white, as shown in the next picture. We point at this with the green arrow.  Find all these buttons on the top of the speaker, as shown in the picture above.

How to Turn On JBL Xtreme 3 Low Frequency Mode

To turn low frequency mode back on, again, press and hold the Volume Down and Bluetooth buttons in until the oval, along with the Power and Bluetooth buttons light up white.  Then release the buttons.  When the the oval goes out, the low frequency mode has resumed once again.

Warning

The drivers really thump when you switch ON the low frequency mode.  So use care in how loudly you play this speaker with the extra bass, to avoid damage to the speaker drivers inside. In fact, if the bass is ever crackling, tapping, or otherwise distorting, turn it down !
