Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The Turtlebox Cub ranks #85 of 120 large speakers by sound quality at $330; the Turtlebox Gen 3 ranks #105 of 113 boombox speakers by sound quality at $430.
Same toughness, half the size. The Cub weighs 5.3 lbs (2.4 kg) with a 4.5 inch woofer and a 1.3 inch tweeter. The Gen 3 is a 9.9 lbs (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.
