Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The Harman Kardon Luna 2 ranks #25 of 179 medium speakers by sound quality at $199.95; the Marshall Middleton II ranks #31 of 120 large speakers by sound quality at $279.99.
The Harman Kardon Luna 2 is the lighter choice. A stylish waterproof speaker with clear, spacious mids, tight bass that stays clean at volume, and stereo pairing with a second unit. At 1.6 lbs (735 g) it weighs much less than the Marshall Middleton II at 4 lbs (1.8 kg). Watch for: Treble can sound bright and edgy, and it loses more output off-axis than some rivals.
The Marshall Middleton II is the longer-running choice. A waterproof stereo speaker with very deep bass for its size, a long battery, a power bank and an app EQ. It is rated for 30 hours of battery against 12 for the Harman Kardon Luna 2. It keeps a wired aux input, which the Harman Kardon Luna 2 lacks. It plays in stereo from a single unit, unlike the Harman Kardon Luna 2. The tradeoff: 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 $279.99 if you want a large speaker instead.
