JBL Xtreme 2 Specs and Features of this Speaker

Here, we list the complete JBL Xtreme 2 speaker specs and give a partial list of this speaker’s useful features.  First, these cover its physical size, weight, waterproof level rating, battery recharge time, and play time.  We also give its frequency response, power output and power bank abilities.  Indeed it’s obvious from reading through these specs that the JBL Xtreme 2 sounds terrific.





Secondly, it plays plenty loud, with its forty watts of total output power. Plus, that hefty driving audio offers more bass than equivalent sized models.

But one of the most useful features, is that this unit works as a power bank as well.  E.g. You can charge your cell phone, tablet, or other mobile device right from this speaker’s 10 amp hour battery.  Thus, the specs by no means belie the quality JBL put into this top notch Bluetooth® powerbank speaker.
