THE SMALL BUT MIGHTY WORKHORSE. RE-ENGINEERED WITH A WIDER SOUNDSTAGE. Loud things come in small packages. Acton III is the most discreet Bluetooth speaker in the home line-up and has an even wider soundstage than its predecessor, offering re-engineered sound for an immersive home audio experience. It delivers all the room-filling Marshall signature sound you’d expect from a home speaker.
ROOM-FILLING SOUND Acton III has an even wider soundstage than its predecessor, delivering room-filling Marshall signature sound that has been re-engineered for a more immersive experience. This new generation of Acton has tweeters angled outwards and updated waveguides to deliver a consistently solid sound that is so wide it chases you around the room. Acton III also features Dynamic Loudness, which adjusts the tonal balance of the sound to ensure your music sounds brilliant at every volume.
PAIR, PLAY AND TURN IT UP Acton III is straight to business, so you can just pair and play without the hassle of a complex set-up. You’ll find everything you need right there on the unit so you can easily control your music without ever picking up your device.
NEXT-GENERATION BLUETOOTH Acton III is ready for the future of Bluetooth technology and has been built to deliver next-generation Bluetooth features the moment they are available. Over the Air (OTA) updates via the app ensure that your speaker is always up-to-date with the latest software and features. This future-proof technology will deliver higher audio quality, while increasing streaming range and improving audio sync.
ICONIC DESIGN THAT STANDS APART Marshall has taken its signature rock ’n’ roll home speaker line-up and given it a stripped-back look that makes a loud statement. Its iconic design knocks all other speakers off the shelf. Signature details such as the Marshall script and brass control knobs adorn the speaker, echoing the legacy of rock ’n’ roll. Choose the finish that fits you – original Black, vintage Cream or relaxed Brown.
A MORE SUSTAINABLE APPROACH While staying true to the iconic design that speaks to the brand’s heritage, Acton III has a PVC-free build that comprises 70% recycled plastic and only vegan materials.
CONNECT AND CONTROL With next-generation Bluetooth 5.2 and the 3.5 mm input, connecting to Acton III and listening to your music has never been so effortless.
