Short answer: the Yeahbox Sonic Boom Ultra for better sound quality, the Tribit Stormbox Blast 2 for the lower price. The Yeahbox Sonic Boom Ultra ranks #10 of 75 boombox speakers at $349.20. The Tribit Stormbox Blast 2 ranks #24 at $299.99, $49.21 cheaper.
What the Tribit Stormbox Blast 2 offers: Pretty deep bass. Watch for: 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
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.
Buy the Tribit Stormbox Blast 2 when the price outweighs sound quality for you, and the Yeahbox Sonic Boom Ultra when sound quality outweighs the price instead.
