Short answer: the JBL Xtreme 5 if you can afford it, the Zealot S97 if you can’t. The Xtreme 5 ranks #2 of 78 large speakers, and the S97 ranks #46, 44 places lower. This is not a photo finish: the Xtreme 5 costs $334.09 more and it sounds like it.
The Xtreme 5 is described in our notes as a fantastic sounding speaker with excellent off-axis dispersion and quite deep bass reaching well below 40Hz, a step up from older JBL portables and enough to beat the Soundcore Boom 2 and Tribit Stormbox Blast on bass depth and clarity. Its main flaws are a hole in the mid-upper bass that EQ can’t fix, weak default presets that mean you’ll want to run the custom EQ, and its high price.
The Zealot S97’s case rests on one thing: bass depth at a very low price. Our notes say there is nothing else at its price with that deep of bass and a reasonable tuning. Set against that, it doesn’t get very loud compared to other speakers in this class, runs a much shorter battery, and is described as pretty heavy for what you get. Reviewers also note the cheaper Zealot S67 reportedly has even deeper bass at the cost of more distortion, so the S97 is not even the last word within its own lineup.
Battery life is not close: the Xtreme 5 is rated for 28 hours against 12 hours for the S97, and only the Xtreme 5 has a removable battery pack.
Buy the JBL Xtreme 5 if sound quality is the priority. It is the better speaker by a wide margin in every way our notes measure.
Buy the Zealot S97 if budget is the deciding factor and you mainly want bass depth at a low price, and can live with modest volume and battery life.

The Two Speakers In Full
JBL Xtreme 5: $399.95 Amazon B&H Photo Video eBay
Pros: Removable battery. Quite deep bass, reaching well below 40Hz. A fantastic sounding speaker with excellent off-axis dispersion, a big step up from older JBL portables. Beats the Soundcore Boom 2 and Tribit Stormbox Blast on bass depth and clarity. Plays clean at volume, unlike the JBL Boombox 4.
Cons: High priced. Some bass boost. A hole in the mid-upper bass which can’t be EQ’d out. Default EQ presets are weak (Signature is boring, Chill and Vocal are close to unusable) - needs the custom EQ to sound its best. Bigger and heavier than the Xtreme 4.
Setup: Try this Oluv EQ for the most neutral sound

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.
