Short answer: the XDOBO Wow Max, if you are buying new. The Harman Kardon Onyx Studio 8 ranks higher than it (#12 vs #21 of 91 boombox speakers, 4.1/5 vs 3.9/5) but is discontinued, so only consider it used; the XDOBO Wow Max is still sold new at $206.09.
The Harman Kardon Onyx Studio 8 is the lighter choice. Claimed 8 hours (manufacturer specified) battery life and up to 96db make its feature set practical for its intended room or portable use. At 7.3 lbs (3.3 kg) it weighs much less than the XDOBO Wow Max at 15.4 lbs (7 kg). Watch for: Warm tuning with boosted bass, not as loud as others, and no water resistance rating.
Why pick the XDOBO Wow Max: Big, loud and bass-heavy, with an eight-driver, 300W layout and bass rated down to 32Hz. Watch for: At low and mid volume the JBL Boombox 4 sounds better in the mids and highs; the Wow Max comes across slightly muted and bass forward there, with its midrange not aimed at ear level.
Buy the XDOBO Wow Max, since the Harman Kardon Onyx Studio 8 is discontinued and only worth hunting down used.

XDOBO Wow Max: $206.09 Amazon eBay
Pros: Big, loud and bass-heavy, with an eight-driver, 300W layout and bass rated down to 32Hz. In side by side tests it sounded better balanced and clearer than the Zealot ZE21, with smooth mids and punchy yet deep bass, handled high volume better than the JBL Boombox 4, which gets screechy and drops bass at max, and clearly beat the Sony ULT Field 7 and W-King X20. Two wireless microphones are included, and it charges over USB-C at up to 20V.
Cons: At low and mid volume the JBL Boombox 4 sounds better in the mids and highs; the Wow Max comes across slightly muted and bass forward there, with its midrange not aimed at ear level. About 7 kg, and only a claimed 8 hours of battery.
