Short answer: the Zealot S97 for deep bass at a low price, the Tronsmart Mirtune S100 for a more balanced tuning. The S97 delivers deep bass and a reasonable tuning for the money, but it does not get very loud compared to other speakers in this class. The Mirtune S100 is reasonably balanced, though it lacks the deeper bass of higher ranked speakers.
On the Tronsmart Mirtune S100 side: Reasonably balanced. The tradeoff: Lacking deeper bass compared to higher ranked speakers.
The case for the Zealot S97: There is nothing else for $48 with that deep of bass and a reasonable tuning. Set against that: Doesn’t get very loud compared to other speakers in this class.
Buy the Tronsmart Mirtune S100 at $79.99 for a medium speaker, or the Zealot S97 at $65.86 for a large speaker instead.

Zealot S97: $65.86 with coupon YZZL10 Aliexpress eBay
Pros: For a compact 3.3kg boombox, the S97 delivers unusually deep, clean-enough bass with a more sensible default balance than many inexpensive Zealot models. It also brings IPX6 protection, aux and microSD playback, power-bank outputs, three EQ presets and PartyAdd linking.
Cons: It is not especially loud for its size, battery life is only a claimed 12 hours, and the bass preset can swamp the rest of the music. There is no app or fine-grained EQ, so the Vocal preset is the only practical way to improve the balance. It is still heavy for a speaker with this output ceiling.
