Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The Minirig 4 with subwoofer ranks #5 of 120 large speakers by sound quality at $290; the Zealot S89 ranks #19 of 113 boombox speakers by sound quality at $193.58.
The Minirig 4 with subwoofer is the lighter pick. A compact speaker and wireless subwoofer pair with some of the most balanced sound available, a long battery and deep, impactful bass. At 3.2 lbs (1.44 kg) it weighs much less than the Zealot S89 at 16.1 lbs (7.3 kg). The tradeoff: Not stereo, app is buggy.
The Zealot S89 is the longer-running, tougher option. A great value boombox with deep bass, very high volume, a 40 hour battery and water resistance for outdoor parties. It is rated for 40 hours of battery against 30 for the Minirig 4 with subwoofer. 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. Watch for: At high volume, listener reports describe the bass as loose or muddy and the overall balance as less clear than better boombox speakers.
Buy the Minirig 4 with subwoofer at $290 if you want a large speaker. Buy the Zealot S89 at $193.58 if you want a boombox speaker instead.
