Short answer: the Havit BassBlast Go, if you are buying new. The Harman Kardon Onyx Studio 8 ranks higher than it (#12 vs #47 of 89 boombox speakers, 4.1/5 vs 3.4/5) but is discontinued, so only consider it used; the Havit BassBlast Go is still sold new at $77.99.
Why pick the Harman Kardon Onyx Studio 8: At 3.3 kg, Harman Kardon Onyx Studio 8 combines a 120mm woofer and 2x 20mm tweeters with Bluetooth and aux. Watch for: Bass is limited by its 35Hz specification.
Why pick the Havit BassBlast Go: Jagist found it a strong value for a medium size boombox, with a lot of bass for its size and a good balance on the Rock EQ. Watch for: In the only side by side against a rated speaker, listeners preferred the W-King H330, and Techder Audios found the Tribit Stormbox Lava clearly better in sound and build.
Buy the Havit BassBlast Go, since the Harman Kardon Onyx Studio 8 is discontinued and only worth hunting down used.
Water resistance is not close: the Havit BassBlast Go is rated at IPX6 (powerful water jets), well ahead of the Harman Kardon Onyx Studio 8 at no water resistance.

Havit BassBlast Go: $77.99 Amazon eBay
Pros: Jagist found it a strong value for a medium size boombox, with a lot of bass for its size and a good balance on the Rock EQ. Two woofers and two tweeters give true stereo from one unit, and it adds IPX6 water resistance, Bluetooth 5.3, the Havit Life app with 8 EQ presets, a 6.35mm microphone input with echo control, aux and USB playback, a small status screen, RGB lights, stereo pairing and a power bank output.
Cons: In the only side by side against a rated speaker, listeners preferred the W-King H330, and Techder Audios found the Tribit Stormbox Lava clearly better in sound and build. Vocals are weaker than rivals’, and owners report the battery drains far faster than its 12 hour rating. The evidence is thin: one comparison and a handful of listening reviews.
