Short answer: the Turtlebox Grande, though neither ranks well in its class. It ranks #81 of 113 boombox speakers by sound quality, rated 2.6/5, at $730. The Turtlebox Gen 3 ranks #105, 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 113 boombox speakers; for better sound, the Tribit Stormbox Blast ranks #2 at $199.99.
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.
