Tribit Stormbox Blast 2 vs Zealot ZE21

Q: Should I buy the Tribit Stormbox Blast 2 or the Zealot ZE21?

Buy the ZE21 for the lower price and higher ranking. Buy the Blast 2 only if raw max volume is the single priority, and even then, check the original Stormbox Blast first, since our notes prefer it outright.

Short answer: the ZE21, and the Blast 2’s own review argues against itself. It ranks #17 of 75 boombox speakers at $247.41; the Stormbox Blast 2 ranks #24 at $279.99, $32.58 more.

Our notes are blunt about the Blast 2: nowhere near as neutral and balanced as the first Blast, and a big downgrade unless you only care about max volume. It sounds muddy with boosted lower and upper bass, made worse by its own Xbass mode, plus boosted treble around 6kHz.

The ZE21 has its own real flaws, a rolled-off top end and a bass EQ our notes call bloated and muddy, but it isn’t being measured against a well-regarded predecessor it fails to live up to the way the Blast 2 is.

Buy the ZE21 for the lower price and higher ranking. Buy the Blast 2 only if raw max volume is the single priority, and even then, check the original Stormbox Blast first, since our notes prefer it outright.

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

Zealot ZE21: $187.15 Amazon Aliexpress eBay

Pros: The ZE21’s main attraction is unusually deep bass for a battery boombox: owner testing finds real output in the 40-50Hz region and audibility down toward the low 30s. Its TWS button can form a stereo pair with another compatible Zealot, and its large, rugged chassis gives it credible party-speaker scale. Measured bass extension of 36Hz (-10dB).

Cons: That deep-bass emphasis comes with a pronounced 60-110Hz kick-bass dip and over-loud 250-600Hz lower mids, which can make rock and pop sound hollow or boxy. The supplied sound modes do not fully correct the tuning; the most positive independent report required source-side parametric EQ. Treble is also soft and clarity trails better-tuned rivals.
