Short answer: the onn Pro X Large Boom Boombox. It ranks #43 of 89 boombox speakers by sound quality, rated 3.4/5, at $199; the Turtlebox Grande ranks #69, rated 2.6/5, and costs $730, so there is not much of a tradeoff to weigh.
The case for the onn Pro X Large Boom Boombox: High rated power for the price at 180W RMS (540W peak). The tradeoff: Bass not as deep as higher ranked speakers like the JBL Boombox 3, JBL Boombox 4, or Tribit Stormbox Blast.
Why pick 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 onn Pro X Large Boom Boombox. It is rated higher for sound quality than the Turtlebox Grande and costs less, so it is the default pick unless a specific strength of the other one matters more to you.

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.
