Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The Turtlebox Cub ranks #60 of 82 large speakers by sound quality at $330; the Turtlebox Gen 3 ranks #71 of 76 boombox speakers by sound quality at $430.
Same toughness, half the size. The Cub weighs 2.4 kg with a 4.5 inch woofer and a 1.3 inch tweeter. The Gen 3 is a 4.5 kg boombox with a 6x9 inch woofer and a 1 inch tweeter. Both are IP67 and crush resistant. Each is rated within its own class.
The full-size Turtlebox is louder, reviewers note, but our notes on it find thin bass, rattles, and loudness claims it never reaches at a standard one meter distance. The Cub has warm, bass-forward tuning, though one reviewer found it loses bass at high volume.
Battery: a claimed 14+ hours for the Cub and 25 for the Gen 3. Both charge over USB-C with a power bank output, and both support Party Mode and stereo pairing.
Buy the Turtlebox Cub ($330) for a large speaker; the Turtlebox Gen 3 ($430) suits a boombox speaker instead.

The Two Speakers In Full
Turtlebox Cub: $330.00 Amazon eBay
Pros: A compact, cube-shaped Turtlebox at 2.4 kg with a real two-way layout: a 4.5 inch woofer and a 1.3 inch titanium tweeter. Reviewers found it very loud for its size, with warm, bass-forward tuning and a bit more bass than the Turtlebox Ranger. IP67 waterproof and dustproof, crush and drop resistant, stainless steel tie-downs, a claimed 14+ hours from a 49.95Wh battery, USB-C charging with a power bank output, stereo pairing and Party Mode.
Cons: The evidence so far is listening impressions from two reviews, with no measurements or side by side tests against other brands. One reviewer found it loses bass at high volume, and it is not as loud as the full-size Turtlebox. Turtlebox’s claimed 118dB is a figure the brand’s larger speakers have not come close to at a standard one meter distance. It is also mono from one unit, and its recessed USB-C port only fits slim cable plugs.

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.
