Short answer: the Minirig 2 with subwoofer for sound, the Sony ULT Field 5 for the outdoors. The Minirig is very balanced but not stereo and its app is buggy, and it costs $62 more. The Sony is IP67 rated, dustproof and water resistant, yet its bass is not as deep as others in the category and the sound is just okay.
What the Minirig mk2 with subwoofer gets right: Very balanced sound. The tradeoff: Not stereo, app is buggy.
On the Sony ULT Field 5 side: IP67 rated, dustproof and water resistant. The tradeoff: Bass not as deep as others in the category, and sound quality overall is just okay.
Worth knowing: the Minirig 2 with subwoofer is discontinued, though it still ranks #7 of 78 large speakers by sound quality, so a used unit beats most of what is still sold new.
Buy the Minirig 2 with subwoofer if sound quality matters more than the price. Buy the Sony ULT Field 5 if the price matters more than sound quality.
Battery life favors the Minirig 2 with subwoofer: rated for 40 hours against 25 hours for the Sony ULT Field 5.
If water resistance matters to you, the Sony ULT Field 5 at IP67 (brief submersion) holds up far better than the Minirig 2 with subwoofer at Splash resistant (splashing).

Sony ULT Field 5: $198 Amazon eBay
Pros: A tough 3.3kg portable with IP67 protection, LDAC/AAC support, aux input, a 10-band app EQ, Party Connect, USB-C power-bank output and a claimed 25-hour battery. Reviews find it energetic and dynamic with substantial bass, enough volume for a yard, and two ULT modes that let bass-focused listeners choose a deeper or punchier presentation.
Cons: It prioritizes bass and loudness over fidelity: reviews find the upper mids and highs subdued, with limited stereo separation and soundstage depth. Deep bass is less authoritative than the enclosure suggests, and the loud confirmation tone when pressing the ULT button is an unnecessary annoyance. Use the app EQ and audition it before buying for detail-focused music.
