These are not really the same size class, and that is the honest framing here. The Harman Kardon Luna 2 ranks #22 of 138 medium speakers by sound quality at $199.95; the JBL Xtreme 5 ranks #2 of 77 large speakers by sound quality at $399.95.
What the Harman Kardon Luna 2 offers: 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. The tradeoff: 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.
On the JBL Xtreme 5 side: Removable battery. Quite deep bass, reaching well below 40Hz. A fantastic sounding speaker with excellent off-axis dispersion, a big step up from older JBL portables. Beats the Soundcore Boom 2 and Tribit Stormbox Blast on bass depth and clarity. Watch for: High priced. Some bass boost. A hole in the mid-upper bass which can’t be EQ’d out. Default EQ presets are weak (Signature is boring, Chill and Vocal are close to unusable) - needs the custom EQ to sound its best. Bigger and heavier than the Xtreme 4.
Buy the Harman Kardon Luna 2 at $199.95 if you want a medium speaker. Buy the JBL Xtreme 5 at $399.95 if you want a large speaker instead.
If battery life is a priority, the JBL Xtreme 5 is rated for 28 hours versus 12 hours for the Harman Kardon Luna 2.

Harman Kardon Luna 2: $199.95 Amazon B&H Photo Video eBay
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).
