Short answer: the Marshall Kilburn II, if you are buying new. The Harman Kardon Citation 200 ranks higher than it (#13 vs #43 of 105 large speakers, 4.5/5 vs 3.8/5) but is discontinued, so only consider it used; the Marshall Kilburn II is still sold new at $279.
The Harman Kardon Citation 200 is the better-sounding, tougher option. Deeper bass than any Onyx. It is rated IPX4 against IPX2 for the Marshall Kilburn II. Watch for: Overly boomy by default, you can short press the Bluetooth and volume down buttons simultaneously to decrease the bass, and the Bluetooth and volume up buttons simultaneously to increase it.
The Marshall Kilburn II is the longer-running choice. 20W Class D amp + dual 8W tweeters. It is rated for 20 hours of battery against 8 for the Harman Kardon Citation 200. It keeps a wired aux input, which the Harman Kardon Citation 200 lacks. The catch: Boosted upper bass, not very detailed, not as deep bass as competitors, upper mids peak.
Buy the Marshall Kilburn II if you want one new; the Harman Kardon Citation 200 is discontinued, so only look for it used.
