Short answer: the W-King X20. It ranks #38 of 91 boombox speakers by sound quality, rated 3.5/5, at $219.98; the Turtlebox Grande ranks #71, rated 2.6/5, and costs $730, so there is little reason to consider the other one.
Why pick the Turtlebox Grande: 10-inch woofer. It links with other speakers (Turtlebox Party Mode), which the W-King X20 cannot. The tradeoff: In YouTube sound samples it sounds only okay, and bass is shallow for a 10 inch woofer, only down 10dB at about 55Hz.
The W-King X20 is the better-sounding, deeper-bass pick. Its bass reaches about 42Hz before falling 10dB, against 55Hz for the Turtlebox Grande. It has an adjustable EQ, which the Turtlebox Grande lacks. The tradeoff: Rising frequency response but upper treble rolled off, 700Hz and 1.2kHz peaks.
Buy the W-King X20. It is rated higher for sound quality than the Turtlebox Grande and costs less, so only choose the other one for a particular feature it does better.

The Two Speakers In Full
Turtlebox Grande: $730.00 Amazon eBay
Same family: the Turtlebox Cub (smaller model, rated 3/5), the Turtlebox Ranger (smaller model, rated 3.5/5) and the Turtlebox Gen 3 (smaller model, ranked lower, rated 2.1/5). See every Turtlebox generation.
Pros: 10-inch woofer. IP67 submersible shell with crush-proof ABS exterior. 158Wh battery provides ~3 days of playback. Bluetooth 5.4, party mode (100+ speakers). Measured bass extension of ~55Hz (-10dB).
Cons: In YouTube sound samples it sounds only okay, and bass is shallow for a 10 inch woofer, only down 10dB at about 55Hz. It is rated at just 86W, and like the smaller Turtleboxes it won’t reach its claimed 126dB at a standard one meter distance. Expensive for what it delivers. It charges only from its own barrel plug adapter, not USB-C.
