These sit in different size classes, so this is not a straight ranking comparison. The Harman Kardon Luna 2 ranks #25 of 179 medium speakers by sound quality at $199.95; the Klipsch Detroit ranks #81 of 120 large speakers by sound quality at $235.11.
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 Klipsch Detroit at 5.5 lbs (2.5 kg). It has an adjustable EQ, which the Klipsch Detroit lacks. The tradeoff: Treble can sound bright and edgy, and it loses more output off-axis than some rivals.
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 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 catch: Weird boosted upper bass, bass not very deep.
Buy the Harman Kardon Luna 2 ($199.95) for a medium speaker; the Klipsch Detroit ($235.11) suits a large speaker instead.
