Short answer: the Harman Kardon Citation 200. It ranks #13 of 78 against #41 of 78 for the Sony ULT Field 5, and its bass is deeper than any Onyx. The Sony is IP67 rated and dustproof, but its bass is not as deep as others in the category and the source calls the overall sound just okay; the Citation is also cheaper at $130.
The case for the Harman Kardon Citation 200: Deeper bass than any Onyx. Set against that: Overly boomy by default, you can short press the Bluetooth and volume down buttons simultaneously to decrease the bass.
What the Sony ULT Field 5 gets right: IP67 rated, dustproof and water resistant. The catch: Bass not as deep as others in the category, and sound quality overall is just okay.
Worth knowing: the Harman Kardon Citation 200 is discontinued, though it still ranks #13 of 78 large speakers by sound quality, so a used unit beats most of what is still sold new.
Buy the Harman Kardon Citation 200. It ranks higher for sound quality than the Sony ULT Field 5 and costs less, so the other one has nothing left to offer.
Battery life favors the Sony ULT Field 5: rated for 25 hours against 8 hours for the Harman Kardon Citation 200.
There is a real gap in water resistance: the Sony ULT Field 5 at IP67 (brief submersion) against the Harman Kardon Citation 200, which has IPX4 (splashing).

Sony ULT Field 5: $198 Amazon eBay
Pros: A tough 3.3kg portable with IP67 protection, LDAC/AAC support, aux input, a 10-band app EQ, Party Connect, USB-C power-bank output and a claimed 25-hour battery. Reviews find it energetic and dynamic with substantial bass, enough volume for a yard, and two ULT modes that let bass-focused listeners choose a deeper or punchier presentation.
Cons: It prioritizes bass and loudness over fidelity: reviews find the upper mids and highs subdued, with limited stereo separation and soundstage depth. Deep bass is less authoritative than the enclosure suggests, and the loud confirmation tone when pressing the ULT button is an unnecessary annoyance. Use the app EQ and audition it before buying for detail-focused music.
