Short answer: the Harman Kardon Onyx Studio 6. It ranks #11 of 73 boombox speakers by sound quality at $130; the Soundcore Rave Party 2 ranks #42 and costs $199.95, which makes this an easy call rather than a real tradeoff.
What the Harman Kardon Onyx Studio 6 offers: Warm sound with boosted bass. Oluv liked it slightly better than the newer Onyx 7. Watch for: 8 hour battery at medium volume. Not at loud as others.
What the Soundcore Rave Party 2 offers: This speaker may move around in the rankings as we get better sound samples. Watch for: Poor water rating. Bass extension doesn’t seem very good.
Buy the Harman Kardon Onyx Studio 6. It ranks higher for sound quality than the Soundcore Rave Party 2 and costs less, so the other one has nothing left to offer.
There is a real battery-life gap here: the Soundcore Rave Party 2 is rated for 16 hours, the Harman Kardon Onyx Studio 6 only 8 hours.
There is a real gap in water resistance: the Harman Kardon Onyx Studio 6 at IPX7 (brief submersion) against the Soundcore Rave Party 2, which has IPX4 (splashing).
