Short answer: the Zealot S89, because the Blast 2 trades clarity for bass. The S89 is a great value for bass performance, play time and max volume in the boombox class, though it is on the heavy side. The Tribit Stormbox Blast 2 has pretty deep bass, but the source says it sounds quite muddy from boosted lower and upper bass.
Buy the Zealot S89. It is rated higher for sound quality than the Tribit Stormbox Blast 2 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.

The Two Speakers In Full
Zealot S89: $259.99 Amazon AliExpress eBay
Pros: A 7.3kg boombox with a claimed 36Hz bass extension, 40-hour battery life, IPX6 protection, USB-C charging, aux, USB and microSD playback, TWS and multi-speaker PartyAdd. Listener comparisons find it capable of very high output and substantial bass for outdoor use. A great value for its bass, battery life and maximum volume. Measured bass extension of 36Hz (-10dB).
Cons: At high volume, listener reports describe the bass as loose or muddy and the overall balance as less clear than better boombox speakers. The heavy cabinet and basic finish also make it less polished for daily portability, while its multiple EQ modes cannot substitute for a genuinely neutral tuning.

Tribit Stormbox Blast 2: $279.99 Amazon eBay
Older model: the Tribit Stormbox Blast (ranked higher, rated 4.5/5).
Pros: Pretty deep bass. Measured bass extension of 40Hz (-10dB).
Cons: Sounds quite muddy with the boosted lower and upper bass. Boosted treble around 6kHz. Xbass mode makes it sound even more muddy. Nowhere near as neutral and balanced as the first Blast and a big downgrade unless you only care about max volume
Setup: Try the EQ from Alan Ross at this timestamp of his video
