These are not really the same size class, and that is the honest framing here. The Turtlebox Grande ranks #56 of 75 boombox speakers by sound quality at $700; the Soundboks 4 ranks #29 of 51 party speakers by sound quality at $1199.
What the Turtlebox Grande gets right: 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.
What the Soundboks 4 offers: Tied for the loudest battery powered speaker. Removable 40 hour battery. High efficiency drivers reach 2-3x the volume of typical speakers for the same wattage. Watch for: Very large. Not as neutral or as deep of bass as the above Partyboxes. Not stereo. External power brick for charging.
Buy the Turtlebox Grande at $700 if you want a boombox speaker. Buy the Soundboks 4 at $1199 if you want a party speaker instead.
There is a real battery-life gap here: the Soundboks 4 is rated for 40 hours, the Turtlebox Grande only 25 hours.

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.
