Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The Harman Kardon Luna 2 ranks #22 of 138 medium speakers by sound quality at $199.95; the Minirig 3 with subwoofer ranks #6 of 77 large speakers by sound quality at $260.
The case for the Harman Kardon Luna 2: 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. Set against that: 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.
What the Minirig 3 with subwoofer offers: Very balanced sound The tradeoff: Not stereo, app is buggy. Wireless TWS pairing is buggy. Not easy to carry on the go, no handle and there’s 2 pieces. Calls itself splash resistant but has no official water rating. A bit expensive. Has [reliability issues more often than any other speaker]
Buy the Harman Kardon Luna 2 at $199.95 for a medium speaker, or the Minirig 3 with subwoofer at $260 for a large speaker instead.
There is a real battery-life gap here: the Minirig 3 with subwoofer is rated for 30 hours, the Harman Kardon Luna 2 only 12 hours.
There is a real gap in water resistance: the Harman Kardon Luna 2 at IP67 (brief submersion) against the Minirig 3 with subwoofer, which has Splash resistant (splashing).

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).
