Short answer: the W-King T11. It ranks #55 of 113 boombox speakers by sound quality, rated 3.3/5, at $116.57; the Yeahbox Sonic Boom Max 3 ranks #59, rated 3.2/5, and costs $228.99, so there is not much of a tradeoff to weigh.
The W-King T11 is the lighter option. A weather resistant party speaker with deep bass, high volume and a karaoke mic input. At 11.2 lbs (5.1 kg) it weighs noticeably less than the Yeahbox Sonic Boom Max 3 at 16.8 lbs (7.64 kg). The tradeoff: The tuning can sound hollow through the mids, so deep bass does not always translate to natural vocals or instruments.
What the Yeahbox Sonic Boom Max 3 does well: A large party speaker with powerful bass, a big fast charging battery and app EQ for outdoor parties. The tradeoff: There is limited independent testing and the water/dust rating is reported inconsistently across listings.
Buy the W-King T11. It is rated higher for sound quality than the Yeahbox Sonic Boom Max 3 and costs less, so only choose the other one for a particular feature it does better.
