Short answer: it depends on whether you want Marshall’s tuning or a fuller low end. The Stockwell II is possibly the most natural sounding Marshall speaker with excellent off-axis response, but it is not stereo, not very loud and uses added DSP reverb that audio purists may find annoying. The Harman Kardon Luna 2 counters with an articulate, spacious midrange and tight bass from its 62mm x 82mm woofer, though its treble can sound bright and edgy.

Buy the Harman Kardon Luna 2 at $199.95 for a medium speaker, or the Marshall Stockwell II at $229.99 for a large speaker instead.
There is a real battery-life gap here: the Marshall Stockwell II is rated for 20 hours, the Harman Kardon Luna 2 only 12 hours.
Water resistance is not close: the Harman Kardon Luna 2 is rated at IP67 (brief submersion), well ahead of the Marshall Stockwell II at IPX4 (splashing).
