Short answer: the Marshall Middleton II if sound quality matters most, the Marshall Stockwell III if price matters most. The Marshall Middleton II ranks #28 of 78 large speakers at $330. The Marshall Stockwell III ranks #56 at $249.99, $80.01 cheaper.
What the Marshall Middleton II offers: Very deep bass for the size/weight. Watch for: Bass boosted which drowns out the midrange. Dip around 200hz, peak at 1khz, dipped at 1.6khz. Strange frequency response through the mids.
What the Marshall Stockwell III offers: 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. Watch for: 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.
Buy the Marshall Middleton II when sound quality outweighs the price for you, and the Marshall Stockwell III when the price outweighs sound quality instead.
