These sit in different size classes, so this is not a straight ranking comparison. The Harman Kardon Luna 2 ranks #23 of 144 medium speakers by sound quality at $199.95; the Klipsch Detroit ranks #57 of 82 large speakers by sound quality at $235.99.
The case for the Harman Kardon Luna 2: Articulate, spacious midrange with precise imaging and instrument separation. The catch: Treble can sound bright and edgy, and it loses more output off-axis than some rivals.
What the Klipsch Detroit does well: Dual 1” tweeters + 3” woofers deliver excellent sound detail and robust bass. The tradeoff: Weird boosted upper bass, bass not very deep.
Buy the Harman Kardon Luna 2 ($199.95) for a medium speaker; the Klipsch Detroit ($235.99) suits a large speaker instead.
There is a real battery-life gap here: the Klipsch Detroit is rated for 20 hours, the Harman Kardon Luna 2 only 12 hours.

Harman Kardon Luna 2: $199.95 Amazon B&H Photo Video eBay
Older model: the Harman Kardon Luna (rated 4/5).
Pros: Articulate, spacious midrange with precise imaging and instrument separation. Tight, well-controlled bass from the 62mm x 82mm woofer and passive radiator despite the compact body, and it stays cleaner at volume than pricier rivals like the Sonos Play. IP67 rated, and two units pair via AirTouch for true stereo sound.
Cons: Treble can sound bright and edgy, and it loses more output off-axis than some rivals. Some listeners hear mid-range rattling on certain tracks, similar to sibling JBL models. 12-hour battery life trails category leaders like the JBL Charge 6, which doubles it. Single unit is not stereo (1.1 driver layout).
