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 T11 ranks #53, rated 3.3/5, at $116.57, $130.42 cheaper, which does not close the gap in sound quality.
The Zealot S89 is the better-sounding, deeper-bass pick. 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 43Hz for the W-King T11. It is rated for 40 hours of battery against 10 for the W-King T11. It links with other speakers (PartyAdd up to 100 speakers), which the W-King T11 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 T11 is the lighter option. A capable, weather-resistant party speaker with dual 5.25-inch woofers, a measured -10dB bass point around 43Hz, 112dB maximum output, mic/karaoke input, USB/microSD playback, TWS pairing and low-latency aux. At 11.2 lbs (5.1 kg) it weighs noticeably less than the Zealot S89 at 16.1 lbs (7.3 kg). Watch for: The tuning can sound hollow through the mids, so deep bass does not always translate to natural vocals or instruments.
Buy the Zealot S89. It is rated higher for sound quality, and the $130.42 you would save on the W-King T11 does not close the gap.

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.

W-King T11: $116.57 Amazon $169.99 AliExpress $116.57 Lowest eBay
Pros: A capable, weather-resistant party speaker with dual 5.25-inch woofers, a measured -10dB bass point around 43Hz, 112dB maximum output, mic/karaoke input, USB/microSD playback, TWS pairing and low-latency aux. Its deep bass and 5.1kg size make it a strong option when punch and portability matter more than audiophile refinement. Measured bass extension of 43Hz (-10dB).
Cons: The tuning can sound hollow through the mids, so deep bass does not always translate to natural vocals or instruments. There is no app-based fine EQ, battery life is only a claimed 10 hours, and the external power brick is less convenient than USB-C charging.
