JBL Xtreme Specs, Specifications

JBL Xtreme portable Bluetooth speaker, right front corner view.

Here, we list the complete JBL Xtreme speaker specs. To start with, this post cover its physical size, weight, waterproof level certification, battery charge time, and play time. They also give its frequency response, power output and power bank capabilities. Indeed it’s obvious from reading through these specs that the JBL Xtreme sounds terrific.

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

Furthermore, even when playing at top volume, the lithium ion battery can last up to fifteen hours per charge.

But perhaps the most interesting feature, is that this speaker 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 upper crust portable Bluetooth speaker.
