Short answer: the Zealot S89. It ranks #19 of 89 boombox speakers by sound quality, rated 4.0/5, at $259.99. The Tronsmart Fiitune X30 ranks #48, rated 3.3/5, at $144.90, $115.09 cheaper, not enough of a saving to outweigh the sound-quality gap.
The case for the Zealot S89: 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. 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 case for the Tronsmart Fiitune X30: A three-way, six-driver design (racetrack woofer, two midranges, two tweeters and an upward-firing driver) with 80W, Hi-Res certification, LDAC, a claimed 14 hours of battery and IPX6. The catch: Side by side it clearly lost to the Harman Kardon Go + Play 3, the Soundcore Boom 2 and the EarFun UBoom X: listeners described muddy, dark mid-bass that fails to reproduce low notes, dull and underemphasized treble, and a boxy, sterile sound at low volume next to the JBL Xtreme 4.
Buy the Zealot S89. It is rated higher for sound quality, and the $115.09 saving on the Tronsmart Fiitune X30 is not enough to make up the difference.

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.

Pros: A three-way, six-driver design (racetrack woofer, two midranges, two tweeters and an upward-firing driver) with 80W, Hi-Res certification, LDAC, a claimed 14 hours of battery and IPX6. It plays loud with a lot of mid-bass, reviewers found good separation of instruments and voices, and some listeners found it warm and full at high volume.
Cons: Side by side it clearly lost to the Harman Kardon Go + Play 3, the Soundcore Boom 2 and the EarFun UBoom X: listeners described muddy, dark mid-bass that fails to reproduce low notes, dull and underemphasized treble, and a boxy, sterile sound at low volume next to the JBL Xtreme 4.
