Short answer: the JBL Partybox Encore Essential. It ranks #8 of 98 boombox speakers by sound quality, rated 4.2/5, at $329.95. The W-King T11 ranks #53, rated 3.3/5, at $116.57, $213.38 cheaper, not enough of a saving to outweigh the sound-quality gap.
The JBL Partybox Encore Essential is the better-sounding, deeper-bass option. Its bass reaches about 38Hz before falling 10dB, against 43Hz for the W-King T11. It links with other speakers (PartyBoost up to 100 speakers), which the W-King T11 cannot.
The W-King T11 is the longer-running, tougher pick. 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. It is rated for 10 hours of battery against 6 for the JBL Partybox Encore Essential. It is rated IPX6 against IPX4 for the JBL Partybox Encore Essential. Watch for: The tuning can sound hollow through the mids, so deep bass does not always translate to natural vocals or instruments.
Buy the JBL Partybox Encore Essential. It is rated higher for sound quality, and the $213.38 saving on the W-King T11 is not enough to make up the difference.

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.
