Short answer: the Marshall Stanmore III. Both are rated 3.8/5 for sound quality (#6 and #8 of 20 powered desktop speakers), and the Marshall Stanmore III costs $249.99 against $429.99 for the Marshall Stanmore IV, with sound quality a draw, the lower price decides it.
Why pick the Marshall Stanmore III: At 9.7 lbs (4.4 kg), Marshall Stanmore III combines 5” (midrange/woofer), 1x 5” midrange, 2x 0.75” Dome tweeters with Bluetooth, RCA, Aux. The tradeoff: Bass is limited by its 45Hz to 20kHz (Manufacturer specified) specification.
The case for the Marshall Stanmore IV: A 5 inch woofer on a 60W amplifier and two 0.75 inch tweeters on 25W each, now with waveguides and a redesigned bass port, and Marshall rates it down to 36Hz. It supports LDAC Bluetooth, which the Marshall Stanmore III lacks. It links with other speakers (Auracast), which the Marshall Stanmore III cannot. The tradeoff: No independent measurements or side by side comparisons against speakers we rank have been published yet, so it can’t be ranked.

Marshall Stanmore IV: $429.99 each Estimated Amazon eBay
Older models: the Marshall Stanmore III (ranked higher, rated 3.8/5) and the Marshall Stanmore II (ranked lower, rated 3.7/5).
Smaller model: the Marshall Acton IV (estimated 3.7/5).
Pros: A 5 inch woofer on a 60W amplifier and two 0.75 inch tweeters on 25W each, now with waveguides and a redesigned bass port, and Marshall rates it down to 36Hz. Bluetooth 5.3 with SBC, AAC, LDAC and LC3, multipoint, Auracast for linking more speakers, and both 3.5 mm aux and RCA inputs for a turntable. The Marshall app adds EQ and room calibration, and the new M-button jumps to a saved EQ or Spotify Tap.
Cons: No independent measurements or side by side comparisons against speakers we rank have been published yet, so it can’t be ranked. One woofer serves both channels, so its stereo is limited to the tweeters. It needs mains power, with no battery, and it has no Wi-Fi streaming and no microphone for voice control.
