Re-engineered Wider Stereo Soundstage 

This generation of the home line-up has an even wider soundstage than before, delivering heavy Marshall signature sound that has been re-engineered for a more immersive experience. Generation III has tweeters angled outwards and updated waveguides to deliver a consistently solid sound that is so wide it chases you around the room.

Pair, Play and Turn it Up 

These speakers are 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, including the Bluetooth pairing button, power switch, bass and treble controls and the control knob so you can easily control your music without ever picking up your device. 

Next-Generation Bluetooth

Generation 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. 

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. This iconic design knocks all other speakers off the shelf. Signature details such as the Marshall script and brass control knobs adorn each speaker, echoing the legacy of rock ’n’ roll. 

A More Sustainable Approach 

The home line-up 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 takes a more sustainable approach with a PVC-free build made from 70% recycled plastic and only vegan materials. Durable and solid, comprising high-quality materials and components, you can trust that your speaker will last.

While you can control the bass and treble on top of each speaker, you’ll also find additional controls in the app. Just connect to your speaker directly from your device and start listening.
