Sound Quality

The official technical specifications don't disclose anything other than the total power output of the Tronsmart Bang speaker, which is supposedly 60 W split between two stereo channels. The exploded view of the speaker shows the insides in its cylindrical body; there's a pair of woofers (most likely 2.75") flanked by two tweeters (probably 0.8"). The Bang also has two side-facing passive radiators whose purpose is to add bass without needing a voice coil and magnet assembly or being directly driven.

In terms of power, I directly compared the Tronsmart Bang to the JBL Xtreme 2, which has 40 W of power at its disposal. I'm inclined to believe Tronsmart's claims because the Bang is a couple of decibels louder than the Xtreme 2 when both are pushed as loud as they can go. With that in mind, the Bang is undoubtedly a viable choice for an outdoor speaker for a smaller crowd; think a park hangout rather than a massive pool party. It can also be an interesting option for a smaller room. It was perfectly suitable for my home office, a space of some 20 square meters (a little over 215 square feet), in that I didn't feel the need for it to play any louder than it was able to.

During the comparison with the JBL Xtreme 2, I also noticed one other commendable characteristic of the Bang: Its integrated amplifier is carefully matched to the capabilities of its speaker drivers. Regardless of the listening volume, the Bang isn't prone to distortion. There was no audible overextension or bottoming out of the speaker membranes on even exceptionally bass-heavy tracks.


As for the sound quality, the Tronsmart Bang left me with mixed feelings. This speaker has a lot of potential, but you need to know how to tap into it. To make it sound very good—better than the JBL Xtreme 2 in some aspects—you need volume, distance, and the Deep Bass sound profile found within the Tronsmart mobile app. At low volumes, particularly when the Default sound profile is used, the Bang sounds anemic. You can give it some life by activating the Sound Pulse sound profile, which boosts the lows and highs, but you still won't be able to escape from its lack of oomph, which many see as a defining characteristic of any Bluetooth speaker. All that changes for the better once the Deep Bass sound profile is activated. The low end becomes significantly thicker and weightier, instantly making the Bang sound much warmer and pleasant. Why this isn't the default profile for the Tronsmart Bang is beyond me. Tronsmart should definitely consider making it that in a future firmware update or giving its users the choice to manually select their preferred default profile instead of forcing the dullness of the Default sound profile onto them.

With the Deep Bass profile activated, the only remaining thing to do is give the Bang a bit of power and move it away from you. This is the only way to make it sound larger and work around the single-point-of-origin nature of its sound. From a distance of around two meters, the Bang sounds pleasantly spacious. The speaker is surprisingly midrange-forward, which is why there's no risk of vocals getting drowned out by the music regardless of the genre, and I found the treble well balanced. It isn't fatiguing but manages to push out a decent amount of detail. For a more midrange and treble-heavy presentation, you might want to try the Sound Pulse profile. However, it makes vocals sound too shouty for my taste, especially at higher listening volumes.

The integrated Bluetooth 5.0 chip only supports the rudimentary SBC codec. While I didn't run into any issues with connection stability, do keep in mind that you won't have a great time watching videos because the high wireless latency causes the sound to lag behind the picture. The lag can of course be eliminated by using the auxiliary input of the Tronsmart Bang instead of Bluetooth.

Microphone Quality

To test the quality of the microphone integrated into the Tronsmart Bang, I placed the speaker on the table, around a meter from my head, and faced it directly. The speaker was connected to my PC via Bluetooth. I used Audacity to record the sample, and the sample wasn't edited in any way.



This sample only proved what I had already noticed while actively using the speaker. If you want to use its microphone to answer a phone call or issue a voice command, you must position yourself as close to the speaker as possible. From a meter away, I had to speak very loudly to be heard by the person I was talking to, which is why I would regularly end up having the conversation on my phone instead. While not unusable, the microphone isn't good enough to allow you to talk to somebody while doing stuff around your room.
