Yeahbox Sonic Boom Ultra vs Tribit Stormbox Blast

Last updated: September 16, 2026

Short answer: the Tribit Stormbox Blast. It ranks #2 of 75 boombox speakers by sound quality at $199.99; the Yeahbox Sonic Boom Ultra ranks #10 and costs $349.20, so there is little reason to consider the other one.

Yeahbox Sonic Boom Ultra vs Tribit Stormbox Blast

What the Yeahbox Sonic Boom Ultra offers: By far the loudest boombox tested against it, hitting 106-107dB, roughly 3-5dB louder than the JBL Boombox 4, Zealot ZE41, Tribit Stormbox Blast 2, W-King X20, and Hopestar A90/A95. The massive 6x9in racetrack woofer reaches audible bass down to around 30Hz on the Country EQ preset, and a teardown confirmed genuinely robust internals: a thick vented voice coil and a dedicated crossover output per driver. HDMI ARC input/output lets it double as a TV soundbar, a feature none of its direct competitors offer. Watch for: The 500W peak-power rating doesn’t fully hold up: it gets noisy above roughly 80-90% volume, and the midrange isn’t fully refined, sometimes sitting a touch too forward. The custom EQ in the app noticeably reduces bass output compared to the factory presets and doesn’t persist after the speaker powers off. No Auracast, no removable battery, a plastic handle with some flex, and heavy at 11kg (24lb) for $388. Most of the sound-quality coverage comes from enthusiast listening-test comparisons rather than independent measurement.

What the Tribit Stormbox Blast offers: Amazing speaker given its size, competes well with some speakers in the Party size class, bass almost as deep as a 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. Watch for: 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.

Buy the Tribit Stormbox Blast. It ranks higher for sound quality than the Yeahbox Sonic Boom Ultra and costs less, so the other one has nothing left to offer.
