These sit in different size classes, so this is not a straight ranking comparison. The Marshall Woburn III ranks #2 of 25 powered desktop speakers by sound quality at $449.99; the Marshall Bromley 450 ranks #24 of 46 party speakers by sound quality at $599.99.
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 tradeoff: Bass is limited by its ~45Hz specification.
The Marshall Bromley 450 is the battery-powered, tougher choice. A balanced, warm sound with a flat midrange that keeps vocals and instruments clear, plenty of bass rumble and enough treble for energetic vocals, per RTINGS’ lab tests. Its battery is rated for 40 hours, while the Marshall Woburn III needs an outlet. It is rated IP55, while the Marshall Woburn III has no water resistance. It supports AAC Bluetooth, which the Marshall Woburn III lacks. The catch: It is the quietest of its rivals: both the Soundboks Mix and Teufel Rockster Air 2 play louder, and near max volume the bass recedes and the sound gets less composed.
Buy the Marshall Woburn III at $449.99 if you want a powered desktop speaker. Buy the Marshall Bromley 450 at $599.99 if you want a party speaker instead.

Marshall Bromley 450: $599.99 Amazon B&H Photo Video eBay
Same family: the Marshall Bromley 150 (smaller model, estimated 3.8/5) and the Marshall Bromley 750 (larger model, rated 3.6/5).
Pros: A balanced, warm sound with a flat midrange that keeps vocals and instruments clear, plenty of bass rumble and enough treble for energetic vocals, per RTINGS’ lab tests. Drivers on all four sides keep the tonal balance nearly the same from any angle, and M1M Tech Channel found it more open and airy than the Soundboks Mix and Teufel Rockster Air 2, with deeper bass than both. RTINGS measured 18.8 hours of battery from a swappable LiFePO4 pack shared with the Marshall Bromley 750, and it adds IP55 protection, two XLR/6.35mm combo inputs, USB-C audio, Auracast and physical bass and treble knobs.
Cons: It is the quietest of its rivals: both the Soundboks Mix and Teufel Rockster Air 2 play louder, and near max volume the bass recedes and the sound gets less composed. The warm tuning lacks some fine treble detail. There is no graphic EQ, only bass and treble knobs, and its stereo spreads left and right channels around the cabinet, so panned elements can land on the wrong side. At 12.3 kg it has a carry handle but no wheels.
