There are few names in audio that carry the same cultural weight as Marshall. Born from the stages of legendary rock venues and the rehearsal rooms of music history, the British brand has spent decades translating its amplifier heritage into home listening equipment that looks as good as it sounds. Now, Marshall has unveiled the latest evolution of two of its most beloved home speakers, the Acton IV and the Stanmore IV, and in doing so, has raised the bar again for what a premium bookshelf speaker can deliver.
Both models build upon the considerable foundations laid by their predecessors, introducing acoustic upgrades, design refinements, and a suite of new technologies that bring the listening experience firmly into the modern age. For anyone who has long admired Marshall’s ability to marry analogue warmth with contemporary functionality, the fourth generation of these speakers makes the strongest case yet.
A Legacy Of Sound, Refined For Today’s Listener
The Acton and Stanmore have been fixtures in design-conscious homes for well over a decade. Their appeal has always rested on a dual promise: the unmistakable aesthetic of a Marshall amplifier, paired with audio performance that punches well above its price point. The challenge with any fourth iteration is how to improve upon something that already commands a loyal following without losing what made it special in the first place.
Marshall has answered that challenge with characteristic precision. The Acton IV and Stanmore IV both feature upgraded acoustics engineered to deliver a wider soundstage, cleaner bass, and richer sound at any volume. Whether you are filling a large living room at full tilt or listening quietly late at night, both speakers have been tuned to perform with authority and nuance across the entire dynamic range.
Central to this improvement is a redesigned bass port that improves low-end performance, giving each speaker a more defined and controlled bottom end without the muddiness that can plague similarly sized units. Audiophiles will notice it immediately, particularly those who favour genres where bass texture and precision matter most, from jazz to electronic music, soul to classical. This kind of meticulous acoustic engineering mirrors the innovation seen across the broader world of premium technology, much like the brilliant evolution of automotive lighting technology, where incremental refinement yields transformative results.
Thoughtful Engineering: The Detail That Makes The Difference
Beyond the acoustic upgrades, Marshall has applied considerable thought to the physical design of both speakers in ways that speak directly to the realities of modern living. One of the most quietly impressive changes is the repositioning of the cables, which now run underneath each speaker rather than out of the back. The Acton IV and Stanmore IV can now sit flush against a wall without any compromise to sound quality.
For anyone who has ever wrestled with the aesthetic challenge of managing speaker cables in a well-appointed room, this is a genuinely welcome development. It reflects an understanding that the people buying these speakers care as much about how their home looks as how it sounds, and that excellent audio equipment should work with a living space rather than against it.
Both speakers retain Marshall’s signature textured finish and brass control panel, along with the tactile, amp-inspired controls that have become one of the brand’s most recognisable design signatures. Running your fingers across the top of a Marshall home speaker has always felt satisfying in a way that touchscreen-only interfaces simply cannot replicate. The fourth generation preserves that analogue intimacy while layering in contemporary smart features.
Auracast, RCA Connectivity And The M-Button: Modern Features For A Modern Home
Perhaps the most significant new addition across both models is the integration of Auracast™ broadcast audio technology. Auracast is a Bluetooth broadcast audio standard that enables a single audio source to be shared simultaneously with multiple Bluetooth-enabled devices and speakers. In practical terms, this means listeners can create a synchronised multi-speaker experience throughout their home, a feature that was previously the preserve of proprietary multi-room systems at considerably higher price points.
The inclusion of Auracast makes the Acton IV and Stanmore IV the foundation of a genuinely expansive home audio setup, rather than standalone units operating in isolation. It’s a forward-thinking addition that acknowledges the way people increasingly want music to follow them through their homes rather than being confined to a single room.
For vinyl enthusiasts, the addition of RCA connectivity is equally significant. The ability to connect a turntable directly to either speaker without the need for a separate phono stage or additional amplification simplifies the setup considerably. It reinforces Marshall’s commitment to analogue as well as digital listening. In a world where record sales continue to rise year on year, this is a feature that will resonate deeply with a growing community of listeners who have rediscovered, or never abandoned, the warmth and ritual of vinyl.
The newly introduced M-button adds a layer of personalised convenience that feels genuinely useful rather than gimmicky. Positioned for easy access, the button can be configured to provide quick access to EQ settings or to activate Spotify Tap, which resumes your most recently played Spotify content without the need to navigate through the app. It’s a small addition that will nonetheless become a daily habit for many users, a one-touch shortcut to the music you love.
The Marshall App: Personalising Your Sound
Complementing the hardware is the Marshall app, which allows users to fine-tune EQ settings and optimise the speaker’s output depending on its placement within a room. Acoustic environments vary enormously from home to home. A speaker placed in a corner behaves differently to one positioned on an open shelf or against a flat wall, and the ability to compensate for these variables digitally gives listeners a level of control that was once available only through dedicated hi-fi separates.
The app experience reflects Marshall’s broader philosophy: powerful functionality delivered without unnecessary complexity. Users can shape their sound to suit their preferences and their space, whether that means boosting the midrange for vocal clarity, rolling off the treble for late-night listening, or simply leaving everything flat and trusting the speaker’s default tuning, calibrated by the brand’s audio engineers.
Design That Endures: The Marshall Aesthetic
It would be remiss to discuss any new Marshall product without spending a moment on the design, because it remains one of the brand’s most potent differentiators. The Acton IV and Stanmore IV are available in Black and Cream, two finishes that complement the widest possible range of interiors, from the darkly dramatic to the warmly minimalist.
The Black finish carries all the brooding authority you would expect from a brand rooted in rock and roll heritage. The Cream option offers something softer and arguably more versatile, equally at home in a contemporary Scandi-influenced living room as in a more traditional setting. Both finishes are rendered in Marshall’s signature textured vinyl, which ages gracefully and resists the fingerprints and scuffs that plague gloss surfaces.
The brass control knobs for volume, treble, and bass sit atop the speaker in a row that immediately recalls the front panel of a vintage amplifier. They are satisfying to turn, weighted appropriately, and visually striking in a way that elevates the speaker from a mere audio component to an object of genuine aesthetic interest. This is a speaker you display, not hide. That same desire to fuse function with visual drama is evident in other corners of the luxury world, from the C SEED Bugatti N1 Super TV’s MicroLED artistry to the finest handcrafted interiors.
Acton IV And Stanmore IV: Understanding The Difference
For those deliberating between the two models, the choice broadly comes down to room size and listening volume requirements. The Stanmore IV, priced at £349.99, is the larger of the two and is suited to bigger spaces where its additional scale and power delivery can be fully appreciated. The Acton IV, at £259.99, is the more compact option, but compact in Marshall’s vocabulary still means commanding. It’s more than capable of filling a generously sized room with rich, detailed sound.
Both speakers share the same core feature set, including Auracast, RCA connectivity, the M-button, the redesigned bass port, and compatibility with the Marshall app. The decision between them is therefore less about functionality and more about matching the speaker to the physical dimensions of your space.
Availability And Pricing
The Marshall Acton IV is priced at £259.99 and the Stanmore IV at £349.99. Both models are available now in Black and Cream directly from Marshall’s official website, and will also be available through select retailers.
A New Standard For The Home Speaker
The Acton IV and Stanmore IV represent a meaningful step forward for Marshall’s home audio range. Acoustic performance and design integrity remain at the heart of both products, but they are now joined by a suite of genuinely useful modern features that make the speakers more versatile, more connected, and more deeply integrated into the rhythms of daily life.
For those who have long appreciated Marshall’s ability to make serious audio equipment feel desirable rather than merely functional, the fourth generation delivers exactly what the brand’s loyal following will have hoped for: more of everything that matters, and nothing that doesn’t.
