Short answer: the Harman Kardon Luna 2 for a single self-contained speaker, the Minirig 4 with subwoofer for deeper bass. The Minirig adds USB-C charging and a wireless subwoofer with deeper, more impactful bass than the old Sub 3, but it is not stereo, the app and TWS pairing are buggy, and it is two pieces with no handle. The Luna 2 counters with tight bass from a 62mm x 82mm woofer and passive radiator at $199.95 versus $290.
Buy the Harman Kardon Luna 2 at $199.95 for a medium speaker, or the Minirig 4 with subwoofer at $290 for a large speaker instead.
There is a real battery-life gap here: the Minirig 4 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 4 with subwoofer, which has Splash resistant (splashing).
