These sit in different size classes, so this is not a straight ranking comparison. The Harman Kardon Luna ranks #26 of 179 medium speakers by sound quality at $290.99; the Klipsch Detroit ranks #81 of 120 large speakers by sound quality at $235.11.
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 Klipsch Detroit at 5.5 lbs (2.5 kg). The tradeoff: Boosted bass, and less detailed than higher-ranked speakers.
The Klipsch Detroit is the longer-running pick. A rugged, fully waterproof stereo boombox with a long battery, fast USB-C charging, and power bank output. 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. It plays in stereo from a single unit, unlike the Harman Kardon Luna. The tradeoff: Weird boosted upper bass, bass not very deep.
Buy the Harman Kardon Luna at $290.99 if you want a medium speaker. Buy the Klipsch Detroit at $235.11 if you want a large speaker instead.
