These sit in different size classes, so this is not a straight ranking comparison. The Bose SoundLink Max ranks #17 of 120 large speakers by sound quality at $399; the Harman Kardon Luna 2 ranks #25 of 179 medium speakers by sound quality at $199.95.
The Bose SoundLink Max is the longer-running pick. A rugged waterproof speaker with deep bass, a very long real world battery and a port that charges your phone. It is rated for 20 hours of battery against 12 for the Harman Kardon Luna 2. It keeps a wired aux input, which the Harman Kardon Luna 2 lacks. The tradeoff: Big peak in the upper bass, dipped midrange and lots of peaks and dips above the midrange.
The Harman Kardon Luna 2 is the lighter option. 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 Bose SoundLink Max at 4.9 lbs (2.2 kg). It has an adjustable EQ, which the Bose SoundLink Max lacks. The catch: Treble can sound bright and edgy, and it loses more output off-axis than some rivals.
Buy the Bose SoundLink Max ($399) for a large speaker; the Harman Kardon Luna 2 ($199.95) suits a medium speaker instead.
