Short answer: the Zealot S89. It ranks #19 of 112 boombox speakers by sound quality, rated 4.0/5, at $193.58; the Tronsmart Bang Max ranks #52, rated 3.4/5, and costs $229.99, so there is little reason to consider the other one.
The Zealot S89 is the better-sounding, longer-running choice. A great value boombox with deep bass, very high volume, a 40 hour battery and water resistance for outdoor parties. It is rated for 40 hours of battery against 24 for the Tronsmart Bang Max. It links with other speakers (PartyAdd up to 100 speakers), which the Tronsmart Bang Max cannot. Watch for: At high volume, listener reports describe the bass as loose or muddy and the overall balance as less clear than better boombox speakers.
The Tronsmart Bang Max is the lighter pick. A loud, feature packed party speaker with big bass, app EQ, lights, and separate mic and guitar inputs. At 12.8 lbs (5.8 kg) it weighs noticeably less than the Zealot S89 at 16.1 lbs (7.3 kg). Watch for: Its bass-first tuning prioritizes impact over accuracy: upper mids and lower treble can sound unnatural, while fine midrange and treble detail are limited.
Buy the Zealot S89. It is rated higher for sound quality than the Tronsmart Bang Max and costs less, which makes it the one to get unless you need something the other one does better.
