Short answer: the Harman Kardon Go + Play 3 is the more natural-sounding choice, while the Tribit Stormbox Blast 2 is for listeners who put deep bass and portable party output first. Harman Kardon is 3 of 113; Tribit is 31 of 113.
The Go + Play 3 reaches exceptionally low for its size and improves the older model’s naturalness. It is not especially loud for this class, has only an eight-hour medium-volume battery estimate, and lacks a water rating.
The Stormbox Blast 2 reaches deeply but its lower and upper bass are heavily boosted, making it sound muddy. That tradeoff can suit bass-forward party listening, but it does not make the Tribit the cleaner music speaker.
Buy the Harman Kardon Go + Play 3 if you want more natural sound and unusually deep bass for indoor listening.
Buy the Tribit Stormbox Blast 2 if a big, bass-heavy portable party speaker is more important than tonal restraint.
If battery life is a priority, the Tribit Stormbox Blast 2 is rated for 30 hours versus 8 hours for the Harman Kardon Go + Play 3.
There is a real gap in water resistance: the Tribit Stormbox Blast 2 at IP67 (brief submersion) against the Harman Kardon Go + Play 3, which has no water resistance.
