Short answer: the JBL Partybox Encore Essential. It ranks #8 of 91 boombox speakers by sound quality, rated 4.2/5, at $329.95; the Turtlebox Grande ranks #71, rated 2.6/5, and costs $730, which makes this an easy call rather than a real tradeoff.
The Turtlebox Grande is the longer-running, tougher pick. 10-inch woofer. It is rated for 25 hours of battery against 6 for the JBL Partybox Encore Essential. It is rated IP67 against IPX4 for the JBL Partybox Encore Essential. The catch: 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 Partybox Encore Essential is the better-sounding, deeper-bass choice. Its bass reaches about 38Hz 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). It has an adjustable EQ, which the Turtlebox Grande lacks.
Buy the JBL Partybox Encore Essential. 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.

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.
