Short answer: a tie on sound quality. Both are rated 3.3/5 (#38 and #39 of 76 boombox speakers) at nearly the same price ($150 vs $149.95), so choose on features and fit.
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. Watch for: The tuning can sound hollow through the mids, so deep bass does not always translate to natural vocals or instruments.
Why pick the Gemini GRV-650L: Pretty amazing value for the money. The tradeoff: Not quite as deep bass as the top ranked speakers.
Buy the W-King T11 or the Gemini GRV-650L on features: they are rated the same for sound quality at close to the same price.

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.
