JBL Xtreme 2 review: A sturdy Bluetooth speaker that’s up for serious partying

People are on the go more than ever, and they want to take their music with them. So, it’s no surprise that portable, battery-powered, are proliferating like crazy. Among them is the new Xtreme 2 from JBL. Let’s find out if it can get the party started during your next outing.


The JBL Xtreme 2 is a nearly cylindrical unit measuring 11.3 x 5.4 x 5.2 inches (width x height x diameter). The extra height is due to the feet that prevent it from rolling around on a flat surface. It tips the scale at a hefty 5.3 pounds, thanks to its sturdy metal construction and tough fabric covering. It comes with a woven nylon strap (with an inline bottle opener, no less!) that lets you sling it over your shoulder. The Xtreme 2 is available in black, dark blue, or forest green.

Two 2.75-inch woofers and two 0.8-inch tweeters face forward, and two 3.5-inch passive bass radiators face outward from the ends of the enclosure. The four active drivers are powered by an internal amp that delivers 10 watts to each driver (40W total) when the Xtreme 2 is connected to an AC power outlet. That amp power is reduced somewhat when the unit is being powered by the battery, but JBL won’t disclose the amp power in that case. The frequency response is specified to extend from 55Hz to 20kHz, with a signal-to-noise ratio of more than 80dB.

The ends of the Xtreme 2 hold 3.5″ passive radiators, which give the bass a boost.

is the primary way to feed music to the Xtreme 2. It supports 4.2 using several profiles, including A2DP 1.3, AVRCP 1.6, HFP 1.6, and HSP 1.2. Interestingly, two devices can be paired to the speaker at the same time. When one is playing and you start playing from the other one, the speaker switches automatically. I suppose this could cause some confusion if two people want to play something at the same time.

In addition, the unit offers a feature called Connect+, which lets it broadcast a Bluetooth signal to as many as 100 other Connect+ devices to spread the music around a much larger area. The transmitter power can reach up to 12.5dBm (0.02W) in a frequency range from 2.402- to 2.480GHz using GFSK, π/4 DQPSK, and 8DPSK modulation. You can also wirelessly connect two Xtreme 2s in a stereo pair.

The Xtreme 2 is waterproof as defined by its IPX7 rating. It can survive being immersed in water to a depth of 1 meter for up to 30 minutes, which means it cannot be damaged by splashing water. So go ahead, take it to your next pool or beach party without worrying about getting it wet or even dropping it in the water. JBL doesn’t publish a rating for dust incursion.

Being waterproof (the speaker carries an IPX7 rating), the Xtreme 2 fits right into any pool party.

Finally, the Xtreme 2 can function as a speakerphone with noise and echo cancelling. Simply enable that function in the JBL Connect app and push the play/pause button when you make or receive a call on the paired phone.

User Interface

The controls on the top of the Xtreme 2 are simplicity itself. From left to right, they include buttons for Bluetooth pairing, volume down, power on/off, Connect+ activation, volume up, and play/pause, which also lets you skip to the next track by pushing it twice. Five tiny LEDs located on the front near the bottom of the speaker indicate the battery level when you first turn the unit on.
