Short answer: the Harman Kardon Onyx Studio 9, if you are buying new. The Harman Kardon Onyx Studio 8 ranks higher than the W-King T11 (#12 vs #53 of 98 boombox speakers) but is discontinued; its replacement, the Harman Kardon Onyx Studio 9, is rated 4.1/5 at $189.99 and is still sold new.
The Harman Kardon Onyx Studio 8 is the better-sounding, deeper-bass option. Claimed 8 hours (manufacturer specified) battery life and up to 96db make its feature set practical for its intended room or portable use. Its bass reaches about 35Hz before falling 10dB, against 43Hz for the W-King T11. At 7.3 lbs (3.3 kg) it weighs noticeably less than the W-King T11 at 11.2 lbs (5.1 kg). The catch: Warm tuning with boosted bass, not as loud as others, and no water resistance rating.
The W-King T11 is the louder, tougher choice. 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. Alan Ross Reviews measured it at 112dB at full volume, against 96dB for the Harman Kardon Onyx Studio 8. It is rated IPX6, while the Harman Kardon Onyx Studio 8 has no water resistance. Watch for: The tuning can sound hollow through the mids, so deep bass does not always translate to natural vocals or instruments.
Buy the Harman Kardon Onyx Studio 9, the replacement for the discontinued Harman Kardon Onyx Studio 8; it is rated higher for sound quality than the W-King T11.

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.
