Short answer: the JBL Partybox 300, on clarity. Both go deep, but the 300 earns its keep with crisp, crystal clear highs and midranges plus hard punchy bass that stays free of muddiness, while the Tribit Stormbox Blast 2 sounds quite muddy from its boosted lower and upper bass. The JBL is the harder one to live with: it is hard to carry, too tall and drags on the ground.
The case for the JBL Partybox 300: Exceptional sound quality with crisp, crystal clear highs and midranges, hard punchy bass without muddiness. The tradeoff: Hard to carry, too tall, drags on the ground.
What the Tribit Stormbox Blast 2 gets right: Pretty deep bass. The catch: Sounds quite muddy with the boosted lower and upper bass.
One note: the JBL Partybox 300 is no longer sold new, but at #10 of 39 party speakers by sound quality it still outranks most current models, so used is worth considering.
Buy the JBL Partybox 300 at $300 for a party speaker, or the Tribit Stormbox Blast 2 at $279.99 for a boombox speaker instead.
Battery life favors the Tribit Stormbox Blast 2: rated for 30 hours against 18 hours for the JBL Partybox 300.
Water resistance is not close: the Tribit Stormbox Blast 2 is rated at IP67 (brief submersion), well ahead of the JBL Partybox 300 at no water resistance.

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
