MARSHALL UNVEILS NEXT-GENERATION ACTON IV AND STANMORE IV SPEAKERS FOR THE HOME

7th of July, 2026 – In this latest update, both sound and usability have been elevated across Acton IV and Stanmore IV. Each speaker benefits from upgraded tweeters and waveguides to deliver a wider, more evenly dispersed and expansive soundstage. A thoughtfully redesigned bass port improves airflow for cleaner, more powerful bass, while bottom-placed cables allow placement flush against the wall without affecting audio quality.

In parallel, Dynamic Loudness ensures music sounds incredible at any volume and that every detail is balanced. At low levels, the sound retains clarity, richness, and warmth, and when turned up, improved limiters help deliver a cleaner sound across both speakers.

Staying true to Marshall’s unmistakable aesthetic, Acton IV and Stanmore IV retain a timeless, analogue feel. They feature beloved design cues to complement any home set-up, from signature PU leather wrapping to the now-iconic salt and pepper fret and amp-inspired controls. The classic brass control panel has been updated to include an improved media jog and signature power switch. Designed with purpose and precision, controls are made to intuitively help users find the best settings and sound. Easily adjust volume, bass, and treble, and manage music playback when playing via Bluetooth. Plus, the addition of a new customisable M-button offers instant access to music or personalised settings.

It’s easy to bring other audio devices into the listening set-up too. With RCA and AUX inputs, vinyl enthusiasts can now connect a record player to bring a warm, timeless sound into any space. No matter the source, each speaker is tuned with precision by in-house acoustic engineers to deliver a sound that has presence and demands attention.

A dedicated Marshall app completes the experience, allowing users to customise sound, adjust EQ presets, and optimise audio with placement compensation so each speaker sounds exactly as it should, wherever placed.

“Since first launching in 2012, Marshall’s home speakers have evolved while remaining true to our heritage. These always-in-place speakers form the foundation of any home setup, with Acton and Stanmore chosen time and again for their iconic design, premium build quality, rich, powerful sound, and intuitive tactile controls. With our fourth generation, the focus has been on protecting and strengthening these core qualities, building on what people love rather than reinventing it” said Simona Berbec, Product Manager at Marshall Group. The MDF cabinet used in Acton IV and Stanmore IV is made from FSC™ 100%‑certified wood and both speakers can be repaired with replaceable parts including the knobs, feet, and the grille.

PLAY TOGETHER WITH MULTI-SPEAKER CONNECTIVITY

With built-in Auracast™ technology, Marshall users can now expand their audio setup and enjoy music playing in sync across multiple Acton IV and Stanmore IV speakers. Acton III and Stanmore III can also join the experience via Marshall’s newly launched streaming hub, Heddon, making it simple to create a seamless multi-speaker listening set-up.
