Short answer: the Turtlebox Grande, though neither ranks well in its class. It ranks #57 of 76 boombox speakers by sound quality, rated 2.6/5, at $730. The Turtlebox Gen 3 ranks #71, rated 2.1/5, at $430, $300 cheaper, which does not close the gap in sound quality. Both are rated below 3.0/5 among the 76 boombox speakers; for better sound, the Tribit Stormbox Blast ranks #2 at $179.99.
Both speakers get called out for the same problem: specs that do not hold up. The Gen 3’s own cons note that Turtlebox sound samples on YouTube reveal it will never hit its claimed 120dB at a reasonable measuring distance, with barely any bass and rattling at high volume. The Grande’s cons say the same thing about its 126dB claim and describe barely any bass for a 10 inch woofer despite the bigger driver. Williston Audio Labs titled its Gen 3 review “EXPOSING This $430 Waterproof Speaker,” which lines up with what the spec sheet suggests here.
The Grande’s bigger hardware does not translate into a clearly better result. It steps up to a 10 inch woofer and 1.25 inch titanium tweeter versus the Gen 3’s 6x9 inch car-style woofer and 1 inch tweeter, and adds a built-in microphone and a 158Wh battery rated for about three days of play. But the extra size and 86W of power, against the Gen 3’s 50W, still gets described as barely any bass for a 10 inch driver.
Everything else matches: both run Bluetooth 5.4 with SBC only, both are IP67 rated, both support Turtlebox Party Mode and USB-C charging, and neither has an app or EQ.
Buy the Grande only if the bigger, tougher shell and three-day battery life matter enough to you to accept the higher price for a similar sound result.
Buy the Gen 3 if you want the Turtlebox design at a lower cost. Its own cons text suggests each generation has mainly added features rather than sound quality, so spending more here does not clearly buy you more accurate audio.

The Two Speakers In Full
Turtlebox Gen 3: $430.00 Amazon eBay
Older models: the Turtlebox Gen 2 (rated 2.1/5) and the Turtlebox (rated 2.1/5).
Pros: Waterproof and crushproof, loud with punchy bass. 25+ hour battery life. USB-C charging and USB-C output charges other devices. True multi-speaker Party Mode added on top of stereo pairing, plus Bluetooth 5.4. Measured bass extension of ~65Hz (-10dB).
Cons: Sounds basically identical to the original and the Gen 2: each generation mainly added features, not sound quality. They pretty much lie about all their specs and sound horrible in all youtube sound samples. Will never hit its claimed 120db 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. Rattles at high volume. Looking at it, it appears to be a generic car 2-way 6x9 speaker in a plastic box.

Turtlebox Grande: $730.00 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). Measured bass extension of ~55Hz (-10dB).
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.
