These sit in different size classes, so this is not a straight ranking comparison. The Harman Kardon Luna 2 ranks #23 of 144 medium speakers by sound quality at $199.95; the Marshall Willen II ranks #11 of 47 small speakers by sound quality at $129.99.
What the Harman Kardon Luna 2 does well: Articulate, spacious midrange with precise imaging and instrument separation. Watch for: Treble can sound bright and edgy, and it loses more output off-axis than some rivals.
Why pick the Marshall Willen II: More balanced than the first Willen, no sharp treble. The catch: Not that deep of bass.
Buy the Harman Kardon Luna 2 ($199.95) for a medium speaker; the Marshall Willen II ($129.99) suits a small speaker instead.

The Two Speakers In Full
Harman Kardon Luna 2: $199.95 Amazon B&H Photo Video eBay
Older model: the Harman Kardon Luna (rated 4/5).
Pros: Articulate, spacious midrange with precise imaging and instrument separation. Tight, well-controlled bass from the 62mm x 82mm woofer and passive radiator despite the compact body, and it stays cleaner at volume than pricier rivals like the Sonos Play. IP67 rated, and two units pair via AirTouch for true stereo sound.
Cons: Treble can sound bright and edgy, and it loses more output off-axis than some rivals. Some listeners hear mid-range rattling on certain tracks, similar to sibling JBL models. 12-hour battery life trails category leaders like the JBL Charge 6, which doubles it. Single unit is not stereo (1.1 driver layout).
