Short answer: the JBL Boombox 3 Wifi. It ranks #20 of 73 boombox speakers by sound quality at $389.95; 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 JBL Boombox 3 Wifi offers: Loudest speaker in the category. Slightly better frequency response than the non-wifi version. Watch for: Bass boosted. Dip at 160hz
Buy the JBL Boombox 3 Wifi. It ranks higher for sound quality than the Turtlebox Grande and costs less, so there is no real case for the other one.
