Short answer: the JBL Boombox 4. It ranks #20 of 98 boombox speakers by sound quality, rated 4.0/5, at $549.95. The Tronsmart Bang 2 Ultra ranks #40, rated 3.6/5, at $349.99, $199.96 cheaper, which does not close the gap in sound quality.
The JBL Boombox 4 is the better-sounding, lighter choice. Pretty insane output capability for the size. At 13.2 lbs (5.98 kg) it weighs much less than the Tronsmart Bang 2 Ultra at 23.3 lbs (10.56 kg). It is rated IP68 against IPX6 for the Tronsmart Bang 2 Ultra. It supports AAC Bluetooth, which the Tronsmart Bang 2 Ultra lacks. Watch for: Pretty overpriced for the category.
What the Tronsmart Bang 2 Ultra does well: Far more output than the Tronsmart Bang 2, with 320W RMS through a 6.9 inch woofer, two mid tweeters and two tweeters, and a reviewer comparing it with the JBL Boombox 4 preferred it for loudness and bass. It keeps a wired aux input, which the JBL Boombox 4 lacks. It has a microphone input for karaoke or announcements, which the JBL Boombox 4 lacks. The tradeoff: No measurements, so its rating is estimated from listening comparisons.
Buy the JBL Boombox 4. It is rated higher for sound quality, and the $199.96 you would save on the Tronsmart Bang 2 Ultra does not close the gap.
About the ratings: the Tronsmart Bang 2 Ultra’s rating is estimated from measured siblings and predecessors rather than its own measurements, with a likely range of 3.3 to 3.9, so this verdict could change once it is measured.

Older models: the JBL Boombox 3 Wifi (ranked lower, rated 3.8/5), the JBL Boombox 3 (ranked lower, rated 3.8/5), the JBL Boombox 2 (ranked lower, rated 3.5/5) and the JBL Boombox (ranked lower, rated 2.9/5). See every JBL Boombox generation.
Pros: Pretty insane output capability for the size. IP68 protection and Auracast pairing with other current JBL speakers. Measured bass extension of 41Hz (-10dB).
Cons: Pretty overpriced for the category. Better than the JBL Boombox 3 mostly because there are more 7 EQ bands instead of just 3 and it can be better tuned. Try Oluv’s EQ for it. Out of the box sounds worse than the JBL Boombox 3. No Aux input.

Tronsmart Bang 2 Ultra: $349.99 Estimated Tronsmart $349.99 eBay
Pros: Far more output than the Tronsmart Bang 2, with 320W RMS through a 6.9 inch woofer, two mid tweeters and two tweeters, and a reviewer comparing it with the JBL Boombox 4 preferred it for loudness and bass. It has wired mic and guitar inputs plus aux, microSD and USB playback, a rated 24 hours of battery, a power bank, Auracast party linking, stereo pairing and app EQ.
Cons: No measurements, so its rating is estimated from listening comparisons. Heavy at 10.56 kg with only a carry handle and no wheels, IPX6 splash resistance rather than waterproofing, and SBC only Bluetooth. Sold in the US only through the Tronsmart store.
