Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The Harman Kardon Luna 2 ranks #23 of 144 medium speakers by sound quality at $199.95; the Marshall Middleton II ranks #31 of 82 large speakers by sound quality at $330.
The case for the Harman Kardon Luna 2: 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 Middleton II: Very deep bass for the size/weight. The catch: Bass boosted which drowns out the midrange.
Buy the Harman Kardon Luna 2 at $199.95 if you want a medium speaker. Buy the Marshall Middleton II at $330 if you want a large speaker instead.
There is a real battery-life gap here: the Marshall Middleton II is rated for 30 hours, the Harman Kardon Luna 2 only 12 hours.

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).

Pros: Very deep bass for the size/weight. Measured bass extension of 38Hz (-10dB).
