Short answer: the Marshall Woburn III. It ranks #2 of 20 powered desktop speakers by sound quality, rated 4.1/5, at $449.99. The Marshall Stanmore IV ranks #8, rated 3.8/5, at $429.99, $20 cheaper, a saving that is not big enough to make up the sound-quality gap.
The case for the Marshall Woburn III: At 16.4 lbs (7.44 kg), Marshall Woburn III combines 6” woofer, 2x 2” midranges, 2x 0.75” Dome tweeters with Bluetooth, HDMI ARC, RCA, Aux. The catch: Bass is limited by its ~45Hz specification.
Why pick 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 Woburn III lacks. It links with other speakers (Auracast), which the Marshall Woburn III cannot. Watch for: No independent measurements or side by side comparisons against speakers we rank have been published yet, so it can’t be ranked.
Buy the Marshall Woburn III. It is rated higher for sound quality, and the $20 you would save on the Marshall Stanmore IV does not close the gap.

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.
