Short answer: the Harman Kardon Citation 200. It ranks #13 of 75 large speakers at $130; the Sony ULT Field 5 ranks #40 and costs $198, so there is not much of a tradeoff to weigh.
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.
One note: the Harman Kardon Citation 200 is discontinued, but it still ranks #13 of 75 large speakers, ahead of most of what is still sold new, so it is worth considering used.
Buy the Harman Kardon Citation 200 if the ranking matters more than the price. Buy the Sony ULT Field 5 if the price matters more than the ranking.
