Short answer: the Harman Kardon Onyx Studio 7. It ranks #14 of 98 boombox speakers by sound quality, rated 4.1/5, at $248.90. The W-King T11 ranks #53, rated 3.3/5, at $116.57, $132.33 cheaper, a saving that is not big enough to make up the sound-quality gap.
The Harman Kardon Onyx Studio 7 is the better-sounding, deeper-bass choice. The addition of dual tweeters gives the Studio 7 a wider, more spacious presentation than older Onyx models. Its bass reaches about 37Hz before falling 10dB, against 43Hz for the W-King T11. At 6.4 lbs (2.9 kg) it weighs much less than the W-King T11 at 11.2 lbs (5.1 kg). It links with other speakers (Wireless Dual Sound), which the W-King T11 cannot. The tradeoff: Consumer Reports finds the bass prominent and boomy, mids hazy, treble slightly smeared and the soundstage congested.
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 7. It is rated IPX6, while the Harman Kardon Onyx Studio 7 has no water resistance. It has an adjustable EQ, which the Harman Kardon Onyx Studio 7 lacks. The catch: 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 7. It is rated higher for sound quality, and saving $132.33 with the W-King T11 does not make up for the sound-quality gap.

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.
