Tribit StormBox Max 60W Portable Bluetooth Speaker with Adjustable XBass and Auracast

The StormBox Max is the successor to Tribit's popular StormBox Pro, with more power, adjustable bass and a compact upright design that's easy to take on trips. Enjoy room-filling 360-degree sound at home, outdoors or on the road, with Bluetooth wireless playback and a wired line-in option.

60W 360-Degree Sound

A 30W downward-firing woofer and four 7.5W tweeters deliver a total of 60 watts. The omnidirectional design spreads sound around the speaker rather than concentrating it in one direction.

Adjustable XBass 2.0 Knob

Turn the dedicated physical knob to tailor bass output to the recording and your preference, rather than relying solely on an app or an on/off bass switch.

What Is Auracast?

Auracast is a Bluetooth audio-broadcast feature that allows a speaker to share audio with multiple Auracast-compatible speakers. Use Auracast to play music through StormBox Max or other Auracast-compatible speakers. Pair two StormBox Max speakers in stereo mode for separate left and right channels.

Bluetooth and Wired Listening

Bluetooth 6.0 supports wireless music and hands-free calling with the built-in microphone. A wired auxiliary input offers another way to listen with an appropriate cable and audio source.

20-Hour Battery and Reverse Charging

Enjoy up to 20 hours of playback.* Recharge via USB-C in approximately four hours with a suitable 5V/3A charger; the speaker can also supply power to another device.

IP68 Protection and Portable Design

Dust- and water-resistant construction, a carrying handle, and an approximately 8 × 4.3 × 4.3-inch body make it practical for travel.

*Battery life based on testing with default EQ at 50% volume. Actual playback time varies with use.
