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 ranks #26 of 179 medium speakers by sound quality at $290.99.
The Bose SoundLink Max is the deeper-bass, longer-running choice. A rugged waterproof speaker with deep bass, a very long real world battery and a port that charges your phone. Its bass reaches about 48Hz before falling 10dB, against 57Hz for the Harman Kardon Luna. It is rated for 20 hours of battery against 12 for the Harman Kardon Luna. It keeps a wired aux input, which the Harman Kardon Luna lacks. Watch for: Big peak in the upper bass, dipped midrange and lots of peaks and dips above the midrange.
The Harman Kardon Luna is the lighter choice. A fully waterproof speaker with fairly balanced, bass rich sound, a separate tweeter, and stereo pairing with a second unit. At 2.5 lbs (1.13 kg) it weighs much less than the Bose SoundLink Max at 4.9 lbs (2.2 kg). The tradeoff: Boosted bass, and less detailed than higher-ranked speakers.
Buy the Bose SoundLink Max ($399) for a large speaker; the Harman Kardon Luna ($290.99) suits a medium speaker instead.
