Short answer: the JBL Boombox 3 Wifi. It ranks #26 of 91 boombox speakers by sound quality, rated 3.8/5, at $389.95; the Turtlebox Grande ranks #71, rated 2.6/5, and costs $730, so there is not much of a tradeoff to weigh.
The case for the Turtlebox Grande: 10-inch woofer. It links with other speakers (Turtlebox Party Mode), which the JBL Boombox 3 Wifi cannot. Watch for: In YouTube sound samples it sounds only okay, and bass is shallow for a 10 inch woofer, only down 10dB at about 55Hz.
The JBL Boombox 3 Wifi is the better-sounding, deeper-bass option. Loudest speaker in the category. Its bass reaches about 43Hz before falling 10dB, against 55Hz for the Turtlebox Grande. At 14.6 lbs (6.6 kg) it weighs noticeably less than the Turtlebox Grande at 18.8 lbs (8.53 kg). The catch: Bass boosted.
Buy the JBL Boombox 3 Wifi. It is rated higher for sound quality than the Turtlebox Grande and costs less, which makes it the one to get unless you need something the other one 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.
