Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The Turtlebox Grande ranks #56 of 75 boombox speakers by sound quality at $700; the Soundboks Go ranks #34 of 51 party speakers by sound quality at $799.
The case for the Turtlebox Grande: 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). The catch: 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.
On the Soundboks Go side: Exceptional 40-hour battery life at mid-volume (10 hours at full volume), swappable design (second battery $200 available). 7.8Ah Li-ion with external charging option and pass-through charging capability. 121dB max volume (Bass+ mode). The tradeoff: Not as loud as the other Soundboks. Not as neutral or as much bass as the above Partyboxes. Not stereo. External power brick for charging.
Buy the Turtlebox Grande at $700 for a boombox speaker, or the Soundboks Go at $799 for a party speaker instead.
If battery life is a priority, the Soundboks Go is rated for 40 hours versus 25 hours for the Turtlebox Grande.
Water resistance is not close: the Turtlebox Grande is rated at IP67 (brief submersion), well ahead of the Soundboks Go at no water resistance.

The Two Speakers In Full
Turtlebox Grande: $700.00 Amazon eBay
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).
Cons: 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.
