The Two Speakers In Full
Minirig 4 with subwoofer: $290 Minirigs eBay
Older model: the Minirig 2 with subwoofer (rated 4.5/5).
Pros: Very balanced sound. Finally USB-C charging. Deeper, more impactful bass than the old Sub 3. Subwoofer pairs wirelessly and can be placed anywhere in the room for extra bass. Fine-grained tuning via the app - 5-band EQ plus separate bass/treble and subwoofer controls. Sounded more accurate than the JBL Xtreme 5 in a side-by-side comparison, and the whole 2.1 setup is smaller and lighter than it.
Cons: Not stereo, app is buggy. Not easy to carry on the go, no handle and there’s 2 pieces. Calls itself splash resistant but has no official water rating. A bit expensive. Has reliability issues more often than any other speaker. Default out-of-the-box tuning sounds off and needs a custom EQ to sound its best.

Zealot S89: $246.99 Amazon AliExpress eBay
Pros: A 7.3kg boombox with a claimed 36Hz bass extension, 40-hour battery life, IPX6 protection, USB-C charging, aux, USB and microSD playback, TWS and multi-speaker PartyAdd. Listener comparisons find it capable of very high output and substantial bass for outdoor use. A great value for its bass, battery life and maximum volume. Measured bass extension of 36Hz (-10dB).
Cons: At high volume, listener reports describe the bass as loose or muddy and the overall balance as less clear than better boombox speakers. The heavy cabinet and basic finish also make it less polished for daily portability, while its multiple EQ modes cannot substitute for a genuinely neutral tuning.
