Short answer: the Teufel Boomster NG (2017). It ranks #37 of 73 boombox speakers by sound quality; the Turtlebox Grande ranks #54.
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 Teufel Boomster NG (2017) offers: Pretty neutral sound. Removable battery Watch for: Not as deep bass as others in the category. Bass port can make noise. No water rating.
Buy the Turtlebox Grande if the price matters more than sound quality. Buy the Teufel Boomster NG (2017) if sound quality matters more than the price.
If water resistance matters to you, the Turtlebox Grande at IP67 (brief submersion) holds up far better than the Teufel Boomster NG (2017) at no water resistance.
