Short answer: the Citation 200 for bass, the Stockwell II for natural balance. The Citation 200 digs deeper than any Onyx, but it is overly boomy by default; you can short press the Bluetooth and volume down buttons to cut bass or the Bluetooth and volume up buttons to add it. The Stockwell II may be the most natural sounding Marshall speaker, though it is not stereo.
Buy the Marshall Stockwell II new; the Harman Kardon Citation 200 is no longer sold new, so it only makes sense as a used find.
There is a real battery-life gap here: the Marshall Stockwell II is rated for 20 hours, the Harman Kardon Citation 200 only 8 hours.

Marshall Stockwell II: $229.99 Amazon eBay
Newer model: the Marshall Stockwell III, ranked lower, rated 3/5.
Pros: Marshall Stockwell II uses 3” woofer, 2x 2” fullrange tweeters. Its 1.4 kg, claimed 20 hours (Manufacturer specified) battery life, IPX4 protection, aux input, up to 96dB and mono playback make it a practical option for its intended room or portable use. Possibly the most natural sounding Marshall speaker, with excellent off-axis sound. Measured bass extension of 44Hz (-10dB).
Cons: Bass is limited by its 44Hz specification. There is no companion app. No EQ adjustment. Not very loud, and the added DSP reverb may annoy purists.
