Short answer: the W-King D20. It ranks #27 of 70 boombox speakers at $193; the Yeahbox Sonic Boom Max 3 ranks #37 and costs $228.99, so there is not much of a tradeoff to weigh.
On the W-King D20 side: Comes with 2 wireless microphones. Set against that: Rising frequency response but upper treble rolled off, 700hz and 1.2khz peaks.
The case for the Yeahbox Sonic Boom Max 3: 200W RMS (300W peak) true 3-way, 5-driver array. Set against that: A budget import brand with limited independent testing - specs are manufacturer-claimed.
Buy the W-King D20 if the ranking matters more than the price. Buy the Yeahbox Sonic Boom Max 3 if the price matters more than the ranking.
