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 75; Tribit is 24 of 75.
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.
On the Harman Kardon Go + Play 3 side: Warm sound with boosted bass. Set against that: Just a little over half as loud as the higher rated boomboxes.
The case for the Tribit Stormbox Blast 2: Pretty deep bass. The tradeoff: Sounds quite muddy with the boosted lower and upper bass.
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.

The Two Speakers In Full
Harman Kardon Go + Play 3: $385 Amazon eBay
Pros: Warm sound with boosted bass. Deepest bass out of any speaker in this size. Sound is more natural than the Go + Play2. Measured bass extension of 35Hz (-10dB).
Cons: Just a little over half as loud as the higher rated boomboxes. Only 8 hours of battery at medium volume. No water rating.
Setup: Use the hidden EQ modes to adjust the bass up when outside and down when inside. To adjust bass, quickly press the bluetooth and volume down buttons together, the number of light flashes tell you what mode you’re in. To adjust treble, quickly press the volume up and phone buttons at the same time, the number of yellow flashes on the light tell you what mode you are in.

Tribit Stormbox Blast 2: $279.99 Amazon eBay
Pros: Pretty deep bass. Measured bass extension of 40Hz (-10dB).
Cons: Sounds quite muddy with the boosted lower and upper bass. Boosted treble around 6kHz. Xbass mode makes it sound even more muddy. Nowhere near as neutral and balanced as the first Blast and a big downgrade unless you only care about max volume
Setup: Try the EQ from Alan Ross at this timestamp of his video
