Short answer: the Minirig 4 with Subwoofer for bass and tuning, the Stockwell III for one-piece portability. The two-piece Minirig adds a wirelessly-placed subwoofer plus a 5-band EQ and separate bass, treble and sub controls, and owners report it sounding more accurate than the pricier JBL Xtreme 5. It is still two pieces with no carry handle, while the 2.9 lbs (1.3 kg) Stockwell III travels as one unit with a strap for $249.99.
This pits a single-cabinet portable against a modular 2.1 system. The Stockwell III offers a one-piece 2.9 lbs (1.3 kg) 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 Minirig 4 with subwoofer. It is rated higher for sound quality, and saving $40.01 with the Marshall Stockwell III does not make up for the sound-quality gap.
