Marshall Kilburn III Black and Brass: what the 50W figure really is
Marshall publishes amplifier wattage per driver rather than a single system rating, so the 50W on the box needs unpacking. The Kilburn III carries one 30W Class D amplifier on its 4-inch woofer and two 10W Class D amplifiers on the pair of 2-inch full-range drivers. Add those three together and you reach 50W: it is the sum of Marshall’s per-driver amplifier ratings, not an RMS system power measurement and not a peak output claim.
The one output figure Marshall does publish as a measurement is the maximum sound pressure level, 91 dB SPL at one metre. The frequency range runs from 45 Hz to 20,000 Hz and the cabinet is a stereo design, so the two full-range drivers split left and right rather than doubling the same signal. That is the honest ceiling for the Marshall Kilburn III Black and Brass: enough to fill a majlis, a garden terrace or a hotel room, measured at one metre rather than across a lawn.
50+ hours of playtime and a battery you can actually replace
Marshall rates the Kilburn III at more than 50 hours per charge at moderate volume; run the bass knob and the level high and you will see less than that. A full recharge takes about 3 hours with a 30W USB-C PD charger, and Marshall states that 20 minutes on the same charger returns 8 hours of playtime. The speaker’s power input is USB-C at 9V/3A or 5V/3A, so the charger has to be a USB-C PD unit, and Marshall ships only a USB-C cable in the box, not a wall plug.
The detail that matters across years rather than days is that Marshall lists the lithium-ion battery as rechargeable and replaceable. Cells fade with time; when these do, the Marshall Kilburn III Black and Brass can take a fresh pack instead of becoming waste. Marshall also states that 38 percent of the total product is recycled material. What Marshall does not publish is the battery capacity in Wh or mAh, so there is no figure to quote there.
Marshall Kilburn III Black and Brass: Bluetooth 5.3 and Auracast
Wireless is Bluetooth 5.3 with a stated range of 10 metres, and Marshall lists SBC, LC3 and MPEG-2 AAC as the supported codecs. There is no aptX and no LDAC on this model, which is worth knowing if you specifically chase those. Auracast is supported, letting compatible transmitters and receivers share a single broadcast, and Bluetooth multipoint is listed as available, so a laptop and a phone can hold connections at the same time.
The Marshall Kilburn III Black and Brass also carries a 3.5 mm AUX input for sources without Bluetooth. Marshall recommends using the speaker together with the Marshall Bluetooth app for the best experience but states plainly that it also works without the app, which matters if you would rather not install anything to play music.
Marshall Kilburn III Black and Brass: IP54, 2.8 kg and the vinyl finish
The Kilburn III is IP54-rated. Marshall’s own wording is that it is protected from limited dust ingress and water splashes from any direction. That covers rain, spray and a poolside table; it does not cover submersion, and no amount of careful handling changes what an IP54 rating means.
The cabinet measures 273 x 150 x 169 mm and weighs 2.8 kg, carried by a strap-style handle across the top. This is the Black and Brass colourway, the black vinyl wrap with brass-coloured hardware Marshall has used on its guitar amplifiers for decades. Marshall sells the same speaker in Cream, Brown and Pitch Black, so the finish is the only thing that separates this unit from its siblings.
Analogue knobs, the M-button and Dynamic Loudness
The top panel keeps real controls: bass, treble and volume knobs, a power switch, a media jog for skipping tracks, a Bluetooth button and an M-button that recalls presets. Shaping tone by hand on the speaker is quicker than opening an app, and it is the main reason a Marshall feels different from a smart speaker with a fixed voice.
Marshall also lists Dynamic Loudness, described as tuned sound whatever the volume, meaning the balance between bass, mids and treble is intended to hold at low listening levels instead of thinning out. Marshall publishes no measured curve behind that claim for the Marshall Kilburn III Black and Brass, so treat Dynamic Loudness as a tuning approach rather than a number you can compare.
Who This Is Not For
If you want a speaker that can go into the pool, this is not it. IP54 covers splashes and limited dust, never immersion. If you need one unit to cover a large open space or a standing crowd, 91 dB at one metre is modest, and Marshall’s own Tufton reaches 102 dB at the same distance.
If you were hoping to top up a phone from the speaker, Marshall lists no USB power-output function. If you need a speakerphone or a voice assistant, Marshall publishes no microphone in the Kilburn III specification, so plan on a playback-only device. There is no wall charger in the box either, so budget for a 30W USB-C PD charger if you do not own one, because Marshall’s 3-hour and 20-minute charging figures both assume it.
And 2.8 kg in a 273 mm cabinet is a genuine weight. The Marshall Kilburn III Black and Brass is a speaker you carry to a place and set down, not one you clip to a bag for a walk.

Totot delivers across the UAE in up to 3 business days, free on orders from 300 AED. Returns are accepted within 14 days for a defective or non-conforming item, and shipping damage should be reported within 48 hours of delivery so we can act on it.
The Marshall Kilburn III Black and Brass comes with a 1-year warranty from Totot covering manufacturing defects. Because the unit charges over USB-C at 9V/3A or 5V/3A rather than from a mains adaptor, there is no supply-voltage question to check before you plug it in here.

FAQ
Is the Marshall Kilburn III Black and Brass waterproof?
No. It is IP54-rated, which Marshall describes as protection from limited dust ingress and water splashes from any direction. Rain and splashes are fine; submerging it is not covered.
How long does the battery last on one charge?
50+ hours at moderate volume, per Marshall. A 20-minute charge from a 30W USB-C PD charger gives 8 hours of playtime, and a full charge takes about 3 hours.
Can the battery be replaced?
Yes. Marshall lists the pack as a rechargeable, replaceable Li-ion battery, so the Marshall Kilburn III Black and Brass can outlast its first set of cells.
Is the 50W an RMS power rating?
No. 50W is the sum of three per-driver amplifier ratings that Marshall publishes: one 30W Class D on the woofer and two 10W Class D on the full-range drivers. The only measured output Marshall states is 91 dB SPL at one metre.
Is a charger included in the box?
No. The Marshall Kilburn III Black and Brass ships with a USB-C cable, a quick start guide and legal documentation, with no wall charger. Marshall’s charging times assume a 30W USB-C PD charger you supply.
Can two units be linked together?
Yes, in the sense that Marshall lists Auracast support on the Kilburn III, which lets compatible Auracast transmitters and receivers share one broadcast. Marshall does not publish a list of supported speaker-to-speaker combinations, so confirm compatibility before buying a second unit.
