Short answer: the Harman Kardon Onyx Studio 6. It ranks #12 of 75 boombox speakers by sound quality at $130; the Tronsmart Bang Max ranks #36 and costs $229.99, which makes this an easy call rather than a real tradeoff.
What the Harman Kardon Onyx Studio 6 offers: Harman Kardon Onyx Studio 6 uses 2x 75mm woofers + 2x 20mm tweeters. Its 2.94 kg, claimed 8 hours (Manufacturer specified) battery life, IPX7 protection, aux input, up to 96dB and stereo playback make it a practical option for its intended room or portable use. Watch for: Bass is limited by its 37Hz specification. There is no companion app. No EQ adjustment.
What the Tronsmart Bang Max offers: A powerful, feature-rich party speaker with loud, bass-rich output, app EQ, power-bank capability, lighting, TWS/multi-speaker linking, and separate microphone and guitar inputs with independent level control. Reviews find it can fill a large room even at moderate volume, while SoundPulse or custom EQ gives it useful flexibility for parties and casual karaoke. 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. Deep Bass mode can swallow the rest of the mix, volume control is imprecise and some reviewers hear distortion above roughly 98dB. It is a party tool, not a neutral monitor.
Buy the Harman Kardon Onyx Studio 6. It ranks higher for sound quality than the Tronsmart Bang Max and costs less, so the other one has nothing left to offer.
