Short answer: the JBL Boombox 4, if you are buying new. The JBL Boombox 2 ranks higher than the Turtlebox Grande (#40 vs #71 of 91 boombox speakers) but is discontinued; its replacement, the JBL Boombox 4, is rated 4.0/5 at $549.95 and is still sold new.
Why pick the Turtlebox Grande: 10-inch woofer. 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 2 is the better-sounding, deeper-bass pick. 24 hour battery life (default volume); 20+ hours even at 60% volume. Its bass reaches about 46Hz before falling 10dB, against 55Hz for the Turtlebox Grande. At 13 lbs (5.9 kg) it weighs noticeably less than the Turtlebox Grande at 18.8 lbs (8.53 kg). The catch: Somewhat bass heavy and boomy.
Buy the JBL Boombox 4, the replacement for the discontinued JBL Boombox 2; it is rated higher for sound quality than the Turtlebox Grande.

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.
