Short answer: the W-King X20. It ranks #43 of 112 boombox speakers by sound quality, rated 3.5/5, at $219.98; the Tronsmart Bang Max ranks #52, rated 3.4/5, and costs $229.99, so there is not much of a tradeoff to weigh.
Why pick the W-King X20: A loud stereo party speaker with a large subwoofer, a 24 hour battery with power bank, and water resistance. The tradeoff: 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. The catch: 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 X20. It is rated higher for sound quality than the Tronsmart Bang Max and costs less, so only choose the other one for a particular feature it does better.
