Short answer: the Minirig 4 with subwoofer. It ranks #5 of 115 large speakers by sound quality (rated 4.6/5) at $290 and is still sold new; the Soundcore Motion Boom ranks #14 (rated 4.5/5) and is discontinued, so it is only an option used. The Soundcore Motion Boom’s replacement, the Soundcore Boom 2, is rated 4.5/5 at $99.99.
The Soundcore Motion Boom is the tougher pick. A great value waterproof boombox that floats, with loud, bass rich sound, a long battery and a phone charging port. It is rated IPX7 against Splash resistant for the Minirig 4 with subwoofer. It plays in stereo from a single unit, unlike the Minirig 4 with subwoofer. The catch: Not as neutral or detailed as other top ranked speakers.
Why pick the Minirig 4 with subwoofer: A compact speaker and wireless subwoofer pair with some of the most balanced sound available, a long battery and deep, impactful bass. It keeps a wired aux input, which the Soundcore Motion Boom lacks. The catch: Not stereo, app is buggy.
Buy the Minirig 4 with subwoofer. It is rated higher for sound quality, and the Soundcore Motion Boom is discontinued, so it is only available used.
