These are not really the same size class, and that is the honest framing here. The Harman Kardon Luna 2 ranks #25 of 172 medium speakers by sound quality at $199.95; the JBL Xtreme 5 ranks #2 of 105 large speakers by sound quality at $399.95.
The Harman Kardon Luna 2 is the lighter pick. Articulate, spacious midrange with precise imaging and instrument separation. At 1.6 lbs (735 g) it weighs much less than the JBL Xtreme 5 at 6.4 lbs (2.9 kg). The catch: Treble can sound bright and edgy, and it loses more output off-axis than some rivals.
The JBL Xtreme 5 is the longer-running pick. A large 6.4 lbs (2.9 kg) speaker with IP68 waterproofing, a removable 28-hour battery and quite deep bass reaching well below 40Hz. It is rated for 28 hours of battery against 12 for the Harman Kardon Luna 2. It supports AAC Bluetooth, which the Harman Kardon Luna 2 lacks. The catch: High priced.
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.
