Short answer: the Harman Kardon Luna, if you are buying new. The Minirig 3 ranks higher than it (#8 vs #26 of 164 medium speakers, 4.3/5 vs 4.0/5) but is discontinued, so only consider it used; the Harman Kardon Luna is still sold new at $290.99.
The Minirig 3 is the longer-running, lighter option. Modular, can easily attach a subwoofer. It is rated for 30 hours of battery against 12 for the Harman Kardon Luna. At 1.2 lbs (550 g) it weighs much less than the Harman Kardon Luna at 2.5 lbs (1.13 kg). It supports aptX Bluetooth, which the Harman Kardon Luna lacks. Watch for: Calls itself splash resistant and has no official water rating.
The Harman Kardon Luna is the tougher choice. The sound is fairly balanced apart from the boosted bass. It is rated IP67 against Splash resistant for the Minirig 3. The catch: Boosted bass, and less detailed than higher-ranked speakers.
Buy the Harman Kardon Luna if you want one new; the Minirig 3 is discontinued, so only look for it used.

The Two Speakers In Full
Minirig 3: $140 Discontinued eBay
Newer model: the Minirig 4, ranked higher, rated 4.3/5.
Pros: Modular, can easily attach a subwoofer. Measured bass extension of 53Hz (-10dB).
Cons: Not stereo. Calls itself splash resistant and has no official water rating. App is buggy. Wireless TWS pairing is buggy. A bit expensive. Has reliability issues more often than any other speaker. Discontinued; Minirig now sells only the Minirig 4, and the old product page redirects to it.

Harman Kardon Luna: $290.99 Amazon eBay
Newer model: the Harman Kardon Luna 2, ranked higher, rated 4.1/5.
Pros: Harman Kardon Luna uses 48mm x 90mm woofer, 20mm tweeter. Its 1.13 kg, claimed 12 hours (Manufacturer specified) battery life, IP67 protection and mono playback make it a practical option for its intended room or portable use. The sound is fairly balanced apart from the boosted bass. Measured bass extension of 57Hz (-10dB).
Cons: Bass is limited by its 57Hz specification. There is no companion app. No EQ adjustment. Boosted bass, and less detailed than higher-ranked speakers.
