Short answer: both are discontinued, so this only matters if you are buying used. Used, the Minirig 3 with subwoofer is the better pick: it ranks #6 of 103 large speakers by sound quality (rated 4.6/5), against #14 (rated 4.5/5) for the Soundcore Motion Boom. If you want one new, the Minirig 4 with subwoofer replaces the Minirig 3 with subwoofer and is rated 4.6/5 at $290.
The Minirig 3 with subwoofer is the deeper-bass choice. Very balanced sound. Its bass reaches about 47Hz before falling 10dB, against 53Hz for the Soundcore Motion Boom. It keeps a wired aux input, which the Soundcore Motion Boom lacks. Watch for: Not stereo, app is buggy.
The Soundcore Motion Boom is the louder, tougher option. 30W loud bass-heavy sound, excellent budget-friendly value. Alan Ross Reviews measured it at 106dB at full volume, against 103dB for the Minirig 3 with subwoofer. It is rated IPX7 against Splash resistant for the Minirig 3 with subwoofer. It plays in stereo from a single unit, unlike the Minirig 3 with subwoofer. Watch for: Not as neutral or detailed as other top ranked speakers.
Buy the Minirig 3 with subwoofer only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, buy the Minirig 4 with subwoofer, which replaces the Minirig 3 with subwoofer.
