Short answer: the W-King X20S. It ranks #30 of 91 boombox speakers by sound quality (rated 3.8/5) at $150.99 and is still sold new; the Turtlebox ranks #87 (rated 2.1/5) and is discontinued, so it is only an option used.
The W-King X20S is the better-sounding choice. 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 Turtlebox is the lighter choice. Waterproof and crushproof, loud with punchy bass. At 10 lbs (4.54 kg) it weighs noticeably less than the W-King X20S at 13.8 lbs (6.25 kg). The tradeoff: Sounds basically identical to the later Gen 2 and Gen 3: each generation mainly added features, not sound quality.
Buy the W-King X20S. It is rated higher for sound quality; the Turtlebox is no longer sold new.

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: $329 Discontinued eBay
Newer model: the Turtlebox Gen 3, ranked higher, rated 2.1/5.
Pros: Waterproof and crushproof, loud with punchy bass. 25 hour battery life (6 hours at full volume). Pairs with a second unit for stereo. Measured bass extension of ~65Hz (-10dB).
Cons: Sounds basically identical to the later Gen 2 and Gen 3: each generation mainly added features, not sound quality. The nearly identical Gen 3 measured a V shaped tuning, with boosted lows and highs and dipped mids, yet bass only down 10dB at about 65Hz, and only about 12W RMS from its amp; Turtlebox rated this one at just 50W. It rattles at high volume. Nowhere near its claimed 120dB at a standard one meter distance. It charges from an external AC power brick. Inside is essentially a car audio 6x9 two way speaker in a plastic box. Discontinued.
