Short answer: the Monster Rockin’ Roller 270. It ranks #66 of 70 boombox speakers by sound quality at $249; the Turtlebox/Turtlebox G2 ranks #67 and costs $400, so there is not much of a tradeoff to weigh.
What the Turtlebox/Turtlebox G2 gets right: A recognizable rugged design. The catch: it ranks near the bottom of the boombox class here.
On the Monster Rockin’ Roller 270 side: A 100-hour battery, true stereo output across 270° of coverage, wheels, an integrated handle, and a Qi charging pad, for about $150 less. The tradeoff: bass isn’t as deep as competitors, and it’s very heavy.
Buy the Monster Rockin’ Roller 270. It ranks higher for sound quality than the Turtlebox/Turtlebox G2 and costs less, so there is no real case for the other one.

The Two Speakers In Full
Turtlebox/Turtlebox G2: $400 Amazon
Pros: Waterproof and crushproof, loud with punchy bass. 25 hour battery life (6 hours at full volume; 3 hour charge time). USB-C output charges other devices. Pairs with a second Gen 2 for larger groups.
Cons: They pretty much lie about all their specs and sound horrible in all youtube sound samples. Only 50w (from their indigogo page), will never hit 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. Uses external AC power brick to charge. Looking at it, it appears to be a generic car 2-way 6x9 speaker in a plastic box.
