Short answer: the LG Xboom Stage 301 on rank. It places #36 of 113 boombox speakers against the Yeahbox Sonic Boom Max 3’s #59 of 113. The Yeahbox claims 200W RMS (300W peak) from a true 3-way, 5-driver array, but has limited independent testing so those specs are manufacturer-claimed; the LG is a karaoke hub with a replaceable battery, if overpriced for what it is.
Buy the LG Xboom Stage 301. It is rated higher for sound quality, and saving $1 with the Yeahbox Sonic Boom Max 3 does not make up for the sound-quality gap.
