Tronsmart’s Bang SE, like most of the company’s audio products, is a good-sounding speaker offered at an exceptionally affordable price. It’s weatherproof, loud, offers a bit of thump, and can be paired with one another for more pronounced stereo sound. Turn on the RGB light show and party!

Tronsmart Bang SE design and feature set

The Bang SE is the smallest of the Tronsmart Bang series which runs at $110 I burst (the largest) and the intermediate Bang Mini ($90). The Bang SE measures 6.48 inches high (measured at the top of the handle), 11.73 inches wide, 4.68 inches deep, and weighs 4.76 pounds. The handle is fully integrated with attachment points at both ends for the included shoulder strap. The handle is comfortable enough for most cases, but the strap will keep your hands free.

Audio emanations are created using a 40-watt Class-D amplifier driving two 3.93-inch full-range drivers, powered by passive radiators at each end. RGB lights adorn both the speakers and radiators. The Bang and Bang Mini both have separate woofers and tweeters.

As you can see below, the multi-function controls on the top of the unit consist of: Power/Bluetooth pairing, SoundPulse EQ, volume down, play/pause, volume up, TWS (true wireless stereo, for connecting to a second speaker) and light show on/off. The last button also cycles through the speaker’s various RGB festivities.

A large captive rubberized plug on the bottom rear of the unit (part of the IPX6 waterproofing covers the speaker’s reset pinhole), a USB-A port for charging other devices, a USB-C port for charging the unit, a 3.5mm aux input, and a microSD card slot (labeled TF for TransFlash).

Tronsmart claims up to 24 hours of playtime from the 4000mAh battery, but it will drop to 16 hours if you have the nice lights on the whole time.

Is the Tronsmart Bang SE a good speaker?

For the price, the Tronsmart Bang SE sounds very good. The highs are decent; the reasonably defined, if a little muddy midrange; and the bass is pronounced enough for most genres and listeners. That said, I’ve heard thumpier speakers. Also, the sub-bass reproduction is a bit teasing: you can hear it kick in, but only in the 50 to 60Hz range; below it tends to disappear.

There are two Soundpulse EQ settings. One is a fairly flat frequency rolloff and the other (indicated by a small LED) highlights the bass and treble with a slight scoop in the midrange. This was once called “Loudness” and is a common trick. I preferred it with this diffuser.

The Bang SE is a rather directional speaker, meaning that perceived equalization varies greatly with its orientation. Sit directly in front of it and you’ll get much more high-end and clarity. Hear even from a slight angle and that decays slightly but quickly.

There’s also minimal stereo separation with the two speakers both firing directly forward. A slight outward tilt would help with this.

The Tronsmart Bang SE gets very loud, but will distort at its maximum volume. That said, you can hit group levels without crackling speaker artifacts. All in all, the Bang SE is on par with speakers costing significantly more. It’s not audiophile quality, but it’s eminently listenable.

Tronsmart sent me two units. Combined in stereo and positioned correctly, they sounded very, very good. This is my favorite aspect of Tronsmart’s Bang series, they’re so affordable you can buy two and pair them to sonically outperform any single speaker on the market.

I have to say that the Bang SE’s light show isn’t particularly in sync with the music. It sort of floats on the pulse, not quite locking in with transients. In my Speaqua Barnacle X ReviewI praised that speaker for being in sync with its light show simply because so many speakers aren’t.

The Tronsmart Bang SE is a great value in portable Bluetooth speakers

For $70, Tronsmart Bang SE is a steal and even more. And as discussed, buying a pair to plug into stereo costs about as much as a single similar speaker from a more popular brand will cost you. Just be aware of the caveats in the performance section.
