Short answer: the JBL Boombox 4, if you are buying new, though neither ranks well in its class. The JBL Boombox ranks higher than the Turtlebox Grande (#62 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. Both are rated below 3.0/5 among the 91 boombox speakers; for better sound, the Tribit Stormbox Blast ranks #2 at $199.99.
The Turtlebox Grande is the tougher choice. 10-inch woofer. It is rated IP67 against IPX5 for the JBL Boombox. 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 Boombox is the lighter choice. Claimed 24 hours (manufacturer specified) battery life, ipx5 protection and stereo playback make its feature set practical for its intended room or portable use. At 11.5 lbs (5.2 kg) it weighs much less than the Turtlebox Grande at 18.8 lbs (8.53 kg). Watch for: Treble is not very smooth.
Buy the JBL Boombox 4, the replacement for the discontinued JBL Boombox; 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.
