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 X10-1 ranks #84, rated 2.4/5, at $139.99, $107 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 63Hz for the W-King X10-1. It links with other speakers (PartyAdd up to 100 speakers), which the W-King X10-1 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 W-King X10-1 is the lighter option. At 6.5 lbs (2.95 kg) it weighs much less than the Zealot S89 at 16.1 lbs (7.3 kg). Watch for: Rolled off treble, not much bass.
Buy the Zealot S89. It is rated higher for sound quality, and the $107 saving on the W-King X10-1 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.
