Short answer: the Soundcore Boom 2 Plus. It ranks #26 of 70 boombox speakers at $169.99; the Yeahbox Sonic Boom Max 3 ranks #37 and costs $228.99, so there is not much of a tradeoff to weigh.
What the Soundcore Boom 2 Plus gets right: Quite a bit lighter than most of the other boombox size speakers. Set against that: Warm tuning meaning a rolled off treble and some upper bass boost.
On the Yeahbox Sonic Boom Max 3 side: 200W RMS (300W peak) true 3-way, 5-driver array. The catch: A budget import brand with limited independent testing - specs are manufacturer-claimed.
Buy the Soundcore Boom 2 Plus if the ranking matters more than the price. Buy the Yeahbox Sonic Boom Max 3 if the price matters more than the ranking.

Soundcore Boom 2 Plus: $169.99 Amazon Bhphotovideo
Pros: Quite a bit lighter than most of the other boombox size speakers. This speaker will likely move up as we get a good EQ tune that makes it a lot more neutral.
Cons: Warm tuning meaning a rolled off treble and some upper bass boost. Reasonably deep bass, but not as good as the top ranked.
