JBL Partybox Stage 320 vs Tribit Stormbox Blast 2

Last updated: September 26, 2026

These are not really the same size class, and that is the honest framing here. The JBL Partybox Stage 320 ranks #3 of 40 party speakers by sound quality at $499.95; the Tribit Stormbox Blast 2 ranks #25 of 76 boombox speakers by sound quality at $279.99.

JBL Partybox Stage 320 vs Tribit Stormbox Blast 2

Different sizes. The Stage 320 is a 16.5 kg party speaker. The Stormbox Blast 2 is an 8.7 kg boombox. Each is rated within its own class.

The Blast 2 measured about 110dB with bass to about 40Hz, is IP67, and claims 30 hours. It sounds muddy with boosted lower and upper bass, and XBass makes it worse.

The Stage 320 keeps more bass at high volume than the PartyBox 310, and has wheels, a removable battery and mic and guitar inputs.

Buy the JBL Partybox Stage 320 at $499.95 for a party speaker, or the Tribit Stormbox Blast 2 at $279.99 for a boombox speaker instead.

There is a real battery-life gap here: the Tribit Stormbox Blast 2 is rated for 30 hours, the JBL Partybox Stage 320 only 18 hours.

If water resistance matters to you, the Tribit Stormbox Blast 2 at IP67 (brief submersion) holds up far better than the JBL Partybox Stage 320 at IPX4 (splashing).

Tribit Stormbox Blast 2: $279.99 Amazon eBay

Tribit Stormbox Blast 2 ranking card

Older model: the Tribit Stormbox Blast (rated 4.5/5).

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
