Short answer: the W-King T11. It ranks #38 of 76 boombox speakers by sound quality, rated 3.3/5, at $150; the Yeahbox Sonic Boom Max 3 ranks #41, rated 3.2/5, and costs $206.09, so there is not much of a tradeoff to weigh.
What the W-King T11 does well: 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.
What the Yeahbox Sonic Boom Max 3 does well: A large 3-way, 5-driver party speaker with claimed 200W RMS output, a 111Wh battery, USB-C fast charging, app EQ, TWS pairing, and aux, USB and microSD playback. The tradeoff: There is limited independent testing and the water/dust rating is reported inconsistently across listings.
Buy the W-King T11. It is rated higher for sound quality than the Yeahbox Sonic Boom Max 3 and costs less, so only choose the other one for a particular feature it does better.

The Two Speakers In Full
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.

Yeahbox Sonic Boom Max 3: $206.09 Amazon eBay
Pros: A large 3-way, 5-driver party speaker with claimed 200W RMS output, a 111Wh battery, USB-C fast charging, app EQ, TWS pairing, and aux, USB and microSD playback. Listener comparisons describe powerful bass, strong output and decent mids and highs for outdoor party use.
Cons: There is limited independent testing and the water/dust rating is reported inconsistently across listings. Listener comparisons find it less clear and refined than stronger boombox rivals, so its big bass and output are a better fit for parties than critical listening.
