Short answer: the Tronsmart Bang Max for measured bass depth, the Yeahbox Sonic Boom Max 3 for claimed output. The Bang Max has quite deep bass for the size and money, though it shows peaks in the upper mids and lower treble and is not smooth. The Sonic Boom Max 3 claims 200W RMS with 300W peak from a true 3-way, 5-driver array, but it is a budget brand with limited independent testing and manufacturer-claimed specs.
Buy the Tronsmart Bang Max. 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.
