Short answer: the Tribit Stormbox Micro 2 for sound, the Minirig Mini 2 for the subwoofer option. Our notes call the Micro 2 best in class sound, though its phone charging is finicky and usually does not work, and it costs $64.61 less. The Mini 2 takes an easily attached subwoofer but calls itself splash resistant with no official water rating.
Buy the Tribit Stormbox Micro 2. It is rated higher for sound quality than the Minirig Mini 2 and costs less, so only choose the other one for a particular feature it does better.
There is a real gap in water resistance: the Tribit Stormbox Micro 2 at IP67 (brief submersion) against the Minirig Mini 2, which has Splash resistant (splashing).
