Short answer: the Teufel Boomster 2021. It ranks #33 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 2021 offers: Pretty balanced sound, slightly warm Watch for: Not as deep of bass as above ranked speakers. Boosted mid bass compensating for the lack of bass extension.
Buy the Turtlebox Grande if the price matters more than sound quality. Buy the Teufel Boomster 2021 if sound quality matters more than the price.
