Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The Marshall Kilburn III ranks #41 of 97 large speakers by sound quality at $379.99; the Marshall Tufton ranks #76 of 90 boombox speakers by sound quality at $378.99.
The Marshall Kilburn III is the longer-running, lighter choice. Spacious soundstage with broad stereo dispersion from Marshall’s True Stereophonic multi-driver layout, delivering warm, room-filling sound with 45Hz bass extension. It is rated for 50 hours of battery against 20 for the Marshall Tufton. At 6.3 lbs (2.85 kg) it weighs much less than the Marshall Tufton at 10.8 lbs (4.9 kg). It is rated IP54 against IPX2 for the Marshall Tufton. The tradeoff: Noticeable dips in the midrange compromise frequency response neutrality, making vocals and acoustic instruments sound somewhat recessed or muffled compared to more linear competitors like the JBL Xtreme 4 unless the bass dial is dialed back.
The case for the Marshall Tufton: 20 hour battery life; 2.5 hour full charge, or 20-min quick-charge for 4 hours of play. The tradeoff: Not much lower bass, upper bass boomy, boosted treble, not very balanced overall.
Buy the Marshall Kilburn III at $379.99 if you want a large speaker. Buy the Marshall Tufton at $378.99 if you want a boombox speaker instead.

The Two Speakers In Full
Marshall Kilburn III: $379.99 Amazon eBay
Older model: the Marshall Kilburn II (ranked lower, rated 3.8/5).
Pros: Spacious soundstage with broad stereo dispersion from Marshall’s True Stereophonic multi-driver layout, delivering warm, room-filling sound with 45Hz bass extension. Independent physical bass and treble dials allow quick tonal adjustments on the fly, backed by app-based EQ and placement compensation. Battery life is outstanding at up to 50+ hours with USB-C power-bank charging, IP54 splash resistance, 3.5mm aux input, and Bluetooth 5.3 with Auracast broadcast support. Measured bass extension of 45Hz (-10dB).
Cons: Noticeable dips in the midrange compromise frequency response neutrality, making vocals and acoustic instruments sound somewhat recessed or muffled compared to more linear competitors like the JBL Xtreme 4 unless the bass dial is dialed back. Kilburn II retains slightly punchier perceived loudness at maximum volume due to a more aggressive V-shaped contour. At 2.85 kg with only IP54 splash resistance, it is heavy and cannot withstand water immersion. Lacks a built-in microphone and LDAC codec support.
