Marshall Speakers: Six Portables Rated 17 to 50 Hours

Marshall sells six current portable speakers in the US, rated from 17+ to 50+ hours on a charge, and four current home speakers that run on mains power and list no battery. The portables are the Willen II (affiliate link to Amazon, opens in a new tab), Emberton III (affiliate link to Amazon, opens in a new tab), Stockwell III (affiliate link to Amazon, opens in a new tab), Middleton II, Kilburn III (affiliate link to Amazon, opens in a new tab) and Tufton (affiliate link to Amazon, opens in a new tab); the home models are the Acton III (affiliate link to Amazon, opens in a new tab), Acton IV (affiliate link to Amazon, opens in a new tab), Stanmore III (affiliate link to Amazon, opens in a new tab) and Woburn III (affiliate link to Amazon, opens in a new tab).

Prices are Marshall’s US list prices on 3 November 2026. Marshall’s listing showed one price per colourway, with no sale, and advertised early access to a Black Friday sale. This page covers Bluetooth speakers only: Marshall’s headphones and earbuds are out of scope, and so are its TV soundbars (the Heston line) and party speakers (the Bromley line).

Specs are from the Features and specification sections of each speaker’s page on marshall.com. Three of the six are rated IP67, which Marshall says allows submersion at 1 m for 30 minutes. The Stockwell III and Kilburn III are rated against splashes and dust, and the Tufton’s IPX2 is the lowest water rating of the six.

Two of Marshall’s own figures need a note. The Willen II and Emberton III pages list a 2-inch “10 W” full-range driver beside amplifier figures of 38 W and 2 × 38 W; we report both as listed. And the Middleton II page lists the LC3 codec but, unlike the Willen II and Emberton III, does not describe itself as LE Audio-ready.

What changes as you go up

Willen II to Emberton III: battery and stereo. The Emberton III nearly doubles the rated play time, 32+ hours against 17+, and Marshall lists it as stereo, with what it calls True Stereophonic 360° sound; the Willen II is mono. It weighs 1.5 lb against 0.79 lb. Both are IP67 with a built-in microphone, and the Willen II’s Features list a fastening strap.

Emberton III to Stockwell III: battery, inputs and charge-out. The Stockwell III is rated at 40+ hours, adds bass and treble controls, a 3.5 mm input and a USB-C charge-out, and lists Auracast. It gives up water protection to get there: IP55 rather than IP67.

Stockwell III to Middleton II: IP67 and bigger drivers. The Middleton II is the most water-resistant of the three with a charging bank, at IP67, with two 3-inch woofers and two tweeters. Its rated play time is lower than the Stockwell III’s, 30+ hours to 40+, and at 3.9 lb it is heavier.

Kilburn III: the longest rating. Marshall rates the Kilburn III at 50+ hours, the longest of the six, and it lists Auracast and a charging bank. It weighs 6.17 lb and is rated IP54. Its page lists no microphone.

Tufton: the biggest, and the oldest Bluetooth. At 10.8 lb, the Tufton has four amplifiers, a 3.5 mm input and the highest maximum sound pressure Marshall lists among the six, 102 dB at 1 m. It uses Bluetooth 5.0, is rated IPX2 and 20+ hours, and comes with a mains lead.

Marshall’s US store still sells some earlier generations beside these: on 3 November its listing showed the Emberton II at $159.99, the Stockwell II at $229.99 (sold out) and the Kilburn II at $329.99.

All four run on mains power, and the Acton III, Stanmore III and Woburn III list no water resistance and no Wi-Fi. The home line steps up in amplifier power and inputs: the Woburn III is the one with an HDMI input.

The Acton IV is the newer Acton, at $29.99 more than the Acton III on Marshall’s listing, which showed it sold out on 3 November, as it did the Stanmore IV at $429.99. Marshall says the Acton IV has a redesigned bass port and “multi-speaker connectivity” to play in sync across several Auracast devices, and it adds LDAC to its codec list. A codec list says what the speaker accepts, not what a given connection delivers. The Acton IV page also says it works with Heddon, which Marshall calls its music streaming hub, listed at $299.99.

Who each one suits, by the specs

• The smallest and lightest: the Willen II, at 0.79 lb and 3.96 inches square.
• Stereo and IP67 in a small body: the Emberton III, at 1.5 lb and 32+ hours.
• A long day away from a socket: the Kilburn III at 50+ hours, or the lighter Stockwell III at 40+.
• Near water, with a phone to top up: the Middleton II, the IP67 model of the three with a charging bank.
• A room at home with a TV or turntable: the Stanmore III or Woburn III, with RCA inputs, and on the Woburn III an HDMI input. Whether a turntable has its own phono preamp is set out, for one maker, in which Audio-Technica turntable is which.

If you are weighing Marshall against other brands, which JBL speaker is which, the Bose SoundLink range and the Ultimate Ears lineup set out those makers’ lineups the same way. Our portable speaker shortlist, built on published review scores from three outlets, does not include a Marshall.
