Short answer: the JBL Partybox Encore 2. It ranks #4 of 91 boombox speakers by sound quality, rated 4.4/5, at $330; the Turtlebox Grande ranks #71, rated 2.6/5, and costs $730, so there is not much of a tradeoff to weigh.
The Turtlebox Grande is the longer-running, tougher pick. 10-inch woofer. It is rated for 25 hours of battery against 15 for the JBL Partybox Encore 2. It is rated IP67 against IPX4 for the JBL Partybox Encore 2. 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 2 is the better-sounding, deeper-bass option. The Encore 2 improves the original with dome tweeters, a less boomy balance, slightly deeper bass, longer battery life and two included wireless microphones. Its bass reaches about 42Hz before falling 10dB, against 55Hz for the Turtlebox Grande. At 14.1 lbs (6.4 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. The catch: It still lacks some upper-bass punch and cannot match the scale of the larger PartyBoxes.
Buy the JBL Partybox Encore 2. 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.

JBL Partybox Encore 2: $330 Sam’s Club eBay
Older model: the JBL Partybox Encore (ranked lower, rated 4.3/5). See every JBL PartyBox Encore generation.
Same family: the JBL Partybox Encore Essential 2 (larger model, ranked lower, rated 4.3/5).
Pros: The Encore 2 improves the original with dome tweeters, a less boomy balance, slightly deeper bass, longer battery life and two included wireless microphones. Its compact karaoke-ready design and 7-band EQ make it more adaptable indoors than the earlier Encore. Measured bass extension of 42Hz (-10dB).
Cons: It still lacks some upper-bass punch and cannot match the scale of the larger PartyBoxes. The main value is compact karaoke convenience rather than full-range party output.
