Short answer: the Yeahbox Sonic Boom Ultra. It ranks #11 of 112 boombox speakers by sound quality, rated 4.2/5, at $388. The Tribit Stormbox Blast 2 ranks #31, rated 3.8/5, at $279.99, $108.01 cheaper, not enough of a saving to outweigh the sound-quality gap.
The Tribit Stormbox Blast 2 is the lighter option. A big, waterproof party speaker with deep bass, very high volume, a 30 hour battery and two mic inputs. At 19.2 lbs (8.7 kg) it weighs noticeably less than the Yeahbox Sonic Boom Ultra at 24.3 lbs (11 kg). The tradeoff: Sounds quite muddy with the boosted lower and upper bass.
The Yeahbox Sonic Boom Ultra is the better-sounding pick. A massively loud boombox with deep bass, long battery life, and HDMI ARC so it can double as a TV soundbar. The tradeoff: 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.
Buy the Yeahbox Sonic Boom Ultra. It is rated higher for sound quality, and the $108.01 saving on the Tribit Stormbox Blast 2 is not enough to make up the difference.
