Short answer: the Minirig 4 with subwoofer, if you are buying new. The Minirig 3 with subwoofer ranks higher than the Marshall Middleton II (#6 vs #31 of 120 large speakers) but is discontinued; its replacement, the Minirig 4 with subwoofer, is rated 4.6/5 at $290 and is still sold new.
The Minirig 3 with subwoofer is the better-sounding, lighter pick. A compact speaker and subwoofer pair with very balanced sound and a long battery, now discontinued but worth buying used. At 3.1 lbs (1.42 kg) it weighs noticeably less than the Marshall Middleton II at 4 lbs (1.8 kg). The catch: Not stereo, app is buggy.
The Marshall Middleton II is the deeper-bass, tougher choice. A waterproof stereo speaker with very deep bass for its size, a long battery, a power bank and an app EQ. Its bass reaches about 38Hz before falling 10dB, against 47Hz for the Minirig 3 with subwoofer. It is rated IP67 against Splash resistant for the Minirig 3 with subwoofer. It links with other speakers (Marshall Stack), which the Minirig 3 with subwoofer cannot. The catch: Bass boosted which drowns out the midrange.
