Short answer: the Minirig 4 with subwoofer. It ranks #5 of 115 large speakers by sound quality, rated 4.6/5, at $290. The Zealot S97 ranks #63, rated 3.4/5, at $79.98, $210.02 cheaper, not enough of a saving to outweigh the sound-quality gap.
The Zealot S97 is the tougher pick. A budget boombox with surprisingly deep bass for its size, waterproofing, power bank outputs, and microSD and aux playback. It is rated IPX6 against Splash resistant for the Minirig 4 with subwoofer. It links with other speakers (PartyAdd up to 100 speakers), which the Minirig 4 with subwoofer cannot. It plays in stereo from a single unit, unlike the Minirig 4 with subwoofer. The tradeoff: It is not especially loud for its size, battery life is only a claimed 12 hours, and the bass preset can swamp the rest of the music.
The Minirig 4 with subwoofer is the better-sounding, longer-running option. A compact speaker and wireless subwoofer pair with some of the most balanced sound available, a long battery and deep, impactful bass. It is rated for 30 hours of battery against 12 for the Zealot S97. At 3.2 lbs (1.44 kg) it weighs much less than the Zealot S97 at 7.3 lbs (3.3 kg). The catch: Not stereo, app is buggy.
Buy the Minirig 4 with subwoofer. It is rated higher for sound quality, and saving $210.02 with the Zealot S97 does not make up for the sound-quality gap.
