Short answer: the Harman Kardon Luna 2. It ranks #25 of 164 medium speakers by sound quality (rated 4.1/5) at $199.95 and is still sold new; the Tribit Stormbox Pro ranks #46 (rated 3.7/5) and is discontinued, so it is only an option used.
The Harman Kardon Luna 2 is the better-sounding, lighter choice. Articulate, spacious midrange with precise imaging and instrument separation. At 1.6 lbs (735 g) it weighs noticeably less than the Tribit Stormbox Pro at 2.2 lbs (980 g). Watch for: Treble can sound bright and edgy, and it loses more output off-axis than some rivals.
The Tribit Stormbox Pro is the longer-running choice. 24 hour battery life (60% volume, XBass off); doubles as a power bank. It is rated for 24 hours of battery against 12 for the Harman Kardon Luna 2. It supports aptX Bluetooth, which the Harman Kardon Luna 2 lacks. It keeps a wired aux input, which the Harman Kardon Luna 2 lacks. The catch: Bottom woofer was fixed in a later firmware, upgrade for best sound.
Buy the Harman Kardon Luna 2. It is rated higher for sound quality and still sold new, while the Tribit Stormbox Pro is discontinued.

Harman Kardon Luna 2: $199.95 Amazon B&H Photo Video eBay
Older model: the Harman Kardon Luna (ranked lower, 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).
