Short answer: the W-King X20S. It ranks #29 of 89 boombox speakers by sound quality, rated 3.8/5, at $150.99; the Turtlebox Grande ranks #69, rated 2.6/5, and costs $730, so there is little reason to consider the other one.
The case for the W-King X20S: Clearer and smoother than the larger W-King X20 at about half its size and weight, and in side by side tests it held its own against the Harman Kardon Go + Play 3, with nicer, more exposed mids and more volume. Watch for: Less bass and depth than the X20 and about 3dB quieter, and at maximum volume its mids and highs start to drown out the bass.
The case for the Turtlebox Grande: 10-inch woofer. 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.
Buy the W-King X20S. 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.

W-King X20S: $150.99 AliExpress W-King eBay
Pros: Clearer and smoother than the larger W-King X20 at about half its size and weight, and in side by side tests it held its own against the Harman Kardon Go + Play 3, with nicer, more exposed mids and more volume. 140W RMS (180W peak), IPX7, Bluetooth 5.4, a built-in microphone, TF card, USB and aux playback, FM radio, a carry handle and a shoulder strap.
Cons: Less bass and depth than the X20 and about 3dB quieter, and at maximum volume its mids and highs start to drown out the bass. With a flat EQ the bass is cut off, so it needs the bass boost. The JBL PartyBox Encore Essential 2 sounded better in a direct comparison. Sold direct from W-King in the US.

Turtlebox Grande: $730.00 Amazon eBay
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.
