Short answer: the Sony SRS-XG500. It ranks #45 of 73 boombox speakers by sound quality at $334.99; the Turtlebox Grande ranks #54 and costs $730, so there is not much of a tradeoff to weigh.
What the Turtlebox Grande offers: 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). Watch for: They pretty much lie about all their specs and sound just okay in all youtube sound samples. Only 100w will never hit 126db at a reasonable measuring distance. Putting your db meter right against the speaker doesn’t count, 1 meter distance is the standard. Barely any bass for a 10” woofer. Overpriced and not worth it.
What the Sony SRS-XG500 offers: 30 hour battery life; 10-min quick-charge gives 3 hours. Battery care function stops charging at 90% to extend longevity. IP66 water/dust resistant. Two USB-A ports (one charges devices), mic/guitar inputs, AUX. Party mode links 100+ speakers. Watch for: Thuddy upper bass, not as deep bass as others. Speaker will not remain at max volume and will turn itself down automatically.
Buy the Sony SRS-XG500. It ranks higher for sound quality than the Turtlebox Grande and costs less, so there is no real case for the other one.
