As the middleweight speaker of the home line-up, Stanmore III brings expansive Marshall sound in a frame that sits proudly anywhere in your home. Stanmore III has an even wider soundstage than its predecessor, delivering home-filling Marshall signature sound, re-engineered for a more immersive experience. This new generation of Stanmore has tweeters angled outwards and updated waveguides to deliver a consistently solid sound that is so wide it chases you around the room. The two-way driver system delivers a heavy but balanced sound, with crisp, soaring treble and controlled bass that really roars. Built-in Dynamic Loudness adjusts the tonal balance of the sound, ensures your music sounds brilliant at every volume, while Placement Compensation corrects for any nearby reflective surfaces that may affect the sound. Stanmore III is ready for the future of Bluetooth technology and has been built ready to deliver nextgeneration Bluetooth features the moment they are available.

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. It may have an updated, cleaner look but Stanmore III has never felt more Marshall. Choose the finish that fits you – original Black, vintage Cream or relaxed Brown. Stanmore III has music at heart and the environment in mind. While staying true to the iconic design that speaks to the brand’s heritage, this generation has a PVC-free build that comprises 70% recycled plastic and only vegan materials. Stanmore III has a straight-tobusiness design, so you can just pair and play without the hassle of a complex set-up. Easily connect to this speaker from your device using Bluetooth, RCA or 3.5 mm and get listening. Experience the power of Marshall sound with Stanmore III, the middleweight speaker that makes a loud statement in any space.
