Short answer: the Minirig 4 with subwoofer for better sound quality, the Marshall Stockwell III for the lower price. The Minirig 4 with subwoofer ranks #5 of 78 large speakers at $290. The Marshall Stockwell III ranks #56 at $249.99, $40.01 cheaper.
This pits a single-cabinet portable against a modular 2.1 system. The Stockwell III offers a one-piece 1.3kg speaker with a strap and grilles for on-the-go use, at $249.99. The Minirig 4 with Subwoofer pairs a main unit with a wirelessly-placed subwoofer, plus a 5-band EQ and separate bass/treble/sub controls, for $290 - but it’s two pieces with no carry handle.
Choose the Minirig 4 with Subwoofer for tuning flexibility and bass: Owners report it sounding more accurate than the pricier JBL Xtreme 5 in a side-by-side comparison, and its wirelessly-placed subwoofer adds impact the single-cabinet Stockwell III can’t match.
Choose the Stockwell III for actual portability: As one piece with a strap and no setup required, it travels the way the Minirig’s two-piece system, with no handle, doesn’t.
Buy the Marshall Stockwell III when the price outweighs sound quality for you, and the Minirig 4 with subwoofer when sound quality outweighs the price instead.

The Two Speakers In Full
Marshall Stockwell III: $249.99 Marshall eBay
Pros: 40+ hour battery life with a user-replaceable battery, strap, sleeve and grilles. Doubles as a USB-C power bank. IP55 dust/water resistance. App includes parametric EQ, a Soundstage widening control, and wall/corner placement compensation. Endless-rotation control knobs.
Cons: Highs are recessed by default and need the treble control maxed to compensate, still lacking detail even then. Bass tends to sound resonant and boomy, with reported frequency cancellation and phase issues on complex material that EQ doesn’t fully resolve. Oluv’s A/B testing against the outgoing Stockwell 2 finds the default tuning muffled and muddy enough to prefer the seven-year-old original out of the box, and output loses dynamics and bass while turning harsh well below maximum volume. No aptX support.

Minirig 4 with subwoofer: $290 Minirigs eBay
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.
