Short answer: the W-King D20. It ranks #41 of 112 boombox speakers by sound quality, rated 3.6/5, at $193; the Tronsmart Bang Max ranks #52, rated 3.4/5, and costs $229.99, so there is not much of a tradeoff to weigh.
The case for the W-King D20: A loud stereo party speaker with two wireless microphones, a 24 hour battery and water resistance. Watch for: Rising frequency response but upper treble rolled off, 700Hz and 1.2kHz peaks.
Why pick the Tronsmart Bang Max: A loud, feature packed party speaker with big bass, app EQ, lights, and separate mic and guitar inputs. Watch for: Its bass-first tuning prioritizes impact over accuracy: upper mids and lower treble can sound unnatural, while fine midrange and treble detail are limited.
Buy the W-King D20. It is rated higher for sound quality than the Tronsmart Bang Max and costs less, which makes it the one to get unless you need something the other one does better.
