Short answer: the W-King T11. It ranks #53 of 98 boombox speakers by sound quality, rated 3.3/5, at $116.57; the Sony ULT Field 7 ranks #59, rated 3.2/5, and costs $448.99, so there is not much of a tradeoff to weigh.
The W-King T11 is the deeper-bass 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. Its bass reaches about 43Hz before falling 10dB, against 52Hz for the Sony ULT Field 7. The tradeoff: The tuning can sound hollow through the mids, so deep bass does not always translate to natural vocals or instruments.
The Sony ULT Field 7 is the longer-running choice. It is rated for 30 hours of battery against 10 for the W-King T11. It supports LDAC Bluetooth, which the W-King T11 lacks. It links with other speakers (Party Connect up to 100 speakers), which the W-King T11 cannot. The catch: A peak around 8kHz, and bass does not reach as deep as the top-ranked speakers.
Buy the W-King T11. It is rated higher for sound quality than the Sony ULT Field 7 and costs less, which makes it the one to get unless you need something the other one does better.

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.
