Short answer: the Harman Kardon Citation 200 for bass depth, the Luna 2 for midrange clarity. The Citation 200 goes deeper than any Onyx but is overly boomy by default, with a button combo needed to trim the bass. The Luna 2 has an articulate, spacious midrange and tight, well-controlled bass from its 62mm x 82mm woofer and passive radiator, though its treble can sound bright and edgy.
Buy the Harman Kardon Luna 2 ($199.95) for a medium speaker; the Harman Kardon Citation 200 ($130) suits a large speaker instead.
If water resistance matters to you, the Harman Kardon Luna 2 at IP67 (brief submersion) holds up far better than the Harman Kardon Citation 200 at IPX4 (splashing).
