Short answer: the Harman Kardon Luna 2 if sound quality matters most, the Tribit Stormbox 2 if price matters most. The Harman Kardon Luna 2 ranks #23 of 142 medium speakers at $199.95. The Tribit Stormbox 2 ranks #83 at $70, $129.95 cheaper.
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. IP67 rated, and two units pair via AirTouch for true stereo sound. Watch for: 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).
What the Tribit Stormbox 2 offers: A little better sounding than the Stormbox 1, less of a rolled off treble. Keep Xbass on for best frequency response. Watch for: Drivers on the side, so it will have a rolled off treble listening to it face on.
Buy the Harman Kardon Luna 2 if sound quality is the priority over the price, or the Tribit Stormbox 2 if the price is the priority over sound quality.
If battery life is a priority, the Tribit Stormbox 2 is rated for 24 hours versus 12 hours for the Harman Kardon Luna 2.
