Short answer: the Zealot ZE51. It ranks #16 of 76 boombox speakers by sound quality, rated 4.1/5, at $296.39. The W-King T11 ranks #38, rated 3.3/5, at $150, $146.39 cheaper, a saving that is not big enough to make up the sound-quality gap.
The case for the Zealot ZE51: Cleaner sound and a wider stereo soundstage than the Zealot ZE41, with less distortion at high volume for better instrumental detail and clarity. The tradeoff: The Zealot ZE41 still wins on raw bass depth and price.
The case for the W-King T11: 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. The catch: The tuning can sound hollow through the mids, so deep bass does not always translate to natural vocals or instruments.
Buy the Zealot ZE51. It is rated higher for sound quality, and the $146.39 saving on the W-King T11 is not enough to make up the difference.
There is a real battery-life gap here: the W-King T11 is rated for 10 hours, the Zealot ZE51 only 4 hours.

Zealot ZE51: $296.39 after coupon Amazon AliExpress eBay
Pros: Cleaner sound and a wider stereo soundstage than the Zealot ZE41, with less distortion at high volume for better instrumental detail and clarity.
Cons: The Zealot ZE41 still wins on raw bass depth and price. Large and heavy like the rest of the boombox class, and clarity still isn’t up to dedicated hi-fi speakers.

W-King T11: $113.53 Amazon AliExpress 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.
