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

Buy the Tribit Stormbox Blast. It is rated higher for sound quality than the Zealot ZE21 and costs less, which makes it the one to get unless you need something the other one does better.

Short answer: the Tribit Stormbox Blast. It ranks #2 of 98 boombox speakers by sound quality, rated 4.5/5, at $179.99; the Zealot ZE21 ranks #18, rated 4.0/5, and costs $247.41, which makes this an easy call rather than a real tradeoff.

The Tribit Stormbox Blast is the better-sounding, lighter pick. Amazing speaker given its size, competes well with some speakers in the Party size class, bass almost as deep as a JBL Partybox 100. At 12 lbs (5.45 kg) it weighs much less than the Zealot ZE21 at 20.4 lbs (9.27 kg). The catch: Lacks a bit of detail compared to the top ranked speakers in other size categories, dip at 5.5kHz.

The Zealot ZE21 is the deeper-bass, longer-running option. 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 bass reaches about 36Hz before falling 10dB, against 43Hz for the Tribit Stormbox Blast. It is rated for 40 hours of battery against 30 for the Tribit Stormbox Blast. It links with other speakers (PartyAdd up to 100 speakers), which the Tribit Stormbox Blast cannot. The catch: 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.

Newer model: the Tribit Stormbox Blast 2, ranked lower, rated 3.8/5, released Oct 2024. It adds AAC. See every Tribit Stormbox generation.

Same family: the Tribit Stormbox Micro 2 (smaller model, rated 4.5/5), the Tribit Stormbox Flow (smaller model, rated 3.5/5) and the Tribit Stormbox Pro (smaller model, rated 3.7/5).

Pros: Amazing speaker given its size, competes well with some speakers in the Party size class, bass almost as deep as a JBL Partybox 100. Quite neutral in the default and xbass modes, but try Oluv’s EQ or Alan Ross’s EQ for a slightly more neutral sound. Oluv has mentioned v3.5 now uses his EQ as the defaults and sounds extremely good. 2 different light modes or can be turned off. Measured bass extension of 43Hz (-10dB).

Cons: Lacks a bit of detail compared to the top ranked speakers in other size categories, dip at 5.5kHz. Without the above EQ this speaker would rank around #4 in the rankings. The curved underside of the handle makes it a little harder to grip and can be uncomfortable to carry long distances.

Zealot ZE21: $247.41 Amazon $247.41 AliExpress $187.15 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.
