Short answer: the Zealot S89. It ranks #19 of 98 boombox speakers by sound quality, rated 4.0/5, at $246.99. The W-King D10 ranks #76, rated 2.7/5, at $119.98, $127.01 cheaper, which does not close the gap in sound quality.
The Zealot S89 is the better-sounding, deeper-bass choice. A 16.1 lbs (7.3 kg) 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. Its bass reaches about 36Hz before falling 10dB, against 60Hz for the W-King D10. It links with other speakers (PartyAdd up to 100 speakers), which the W-King D10 cannot. The tradeoff: At high volume, listener reports describe the bass as loose or muddy and the overall balance as less clear than better boombox speakers.
The W-King D10 is the lighter option. 70W RMS output with 120W peak power, exceptional 42-hour battery life, power bank function, IPX6 waterproof, 106dB max volume, EQ and bass boost, microphone input for karaoke, MicroSD card support, USB playback, TWS pairing. At 7.9 lbs (3.6 kg) it weighs much less than the Zealot S89 at 16.1 lbs (7.3 kg). The tradeoff: Upper bass boost, bass not that deep.
Buy the Zealot S89. It is rated higher for sound quality, and the $127.01 saving on the W-King D10 is not enough to make up the difference.

Zealot S89: $246.99 Amazon $246.99 AliExpress $193.58 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.
