Marshall Unveils Acton IV and Stanmore IV with Auracast

Marshall Acton IV and Stanmore IV Auracast-enabled Bluetooth speakers are new entries in Marshall’s home audio range that add Auracast support to the company’s speaker lineup. The models introduce a revamped soundstage with a more even frequency response and include a Dynamic Loudness feature that activates limiters at higher volumes to prevent distortion. The speakers connect to the Marshall app, which provides expanded EQ controls and audio placement optimization. Auracast support enables coordinated playback across multiple units.

Visually and mechanically, the Acton IV and Stanmore IV retain Marshall’s classic design, including a cursive logo on salt-and-pepper amp mesh and a brass control dashboard with physical knobs for volume, bass and treble. RCA and AUX ports are placed on the bottom of each unit to allow wall-friendly placement and to simplify connections to record players and other analog sources. The speakers are available in black and cream colorways, with pricing starting at $329.99 for the Acton IV and $429.99 for the Stanmore IV. The new models are compatible with Acton IIIs and Stanmore IIIs for multi-speaker setups.

Marshall’s Acton IV and Stanmore IV are Auracast-enabled Bluetooth speakers introduced as part of the company’s fourth-generation home audio line. The models introduce a revamped soundstage with a more even frequency response. A Dynamic Loudness system activates limiters at higher volumes to prevent distortion. Both Acton IV and Stanmore IV incorporate these audio updates. The announcement presents these changes as the principal technical updates in the new generation.

Both speakers retain tactile physical controls, with a brass control dashboard and dedicated knobs for volume, bass and treble. The classic Marshall cursive logo appears on a salt-and-pepper amp mesh on both models. RCA and AUX ports are located on the bottom of each unit to allow wall-friendly placement and to simplify connections to record players and other analog sources. The ports and control layout allow mixed analog and wireless setups without changing the external control scheme. The design elements and physical interfaces are described as preserved features in the fourth-generation models.

Auracast functionality enables multiple Acton IV and Stanmore IV speakers to play from the same source, and the new models are compatible with Acton IIIs and Stanmore IIIs for combined multi-speaker setups. The speakers connect to the Marshall app, which provides expanded EQ controls and audio placement optimization. The app provides on-device adjustments to tailor frequency balance and speaker placement settings. Auracast-enabled Bluetooth connectivity combined with the app’s controls supports coordinated playback and tuning across units. Availability, colorways and starting prices for the models were published alongside the launch.

Marshall’s Acton IV and Stanmore IV maintain the brand’s established visual identity while presenting the fourth-generation finish described in the product announcement. Both models feature the cursive Marshall logo set into a salt-and-pepper amp mesh and include a brass control dashboard that serves as a prominent visual and tactile element. Physical knobs for volume, bass and treble are mounted on the dashboard, preserving a tactile control scheme rather than moving to touch-only interfaces. The combination of the amp-mesh surface and metal dashboard aligns the new models with the aesthetic of previous Marshall home speakers and keeps the familiar control layout.

The speakers’ build retains the series’ trademark tactile interface, with dedicated mechanical controls that are intended to provide direct adjustment of core audio parameters. RCA and AUX ports are located on the bottom of each unit, which supports wall-friendly placement and straightforward connections to record players and other analog sources without altering the visible front or top control surfaces. The placement of these ports and the continued use of physical knobs reflect a design approach that balances traditional Marshall styling with practical connectivity options. Materials and hardware treatments described for the fourth generation match the brand’s prior hardware-focused presentation.

Marshall’s messaging for the fourth-generation Acton IV and Stanmore IV emphasizes continuity with earlier models and a focus on protecting and strengthening core design qualities rather than performing a complete redesign. The preserved visual markers and manual control philosophy are presented as deliberate elements of that continuity. The described build and control choices are consistent across both Acton IV and Stanmore IV in the product details released at launch. The available sources do not provide this information.

“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,” says Simona Berbec, Product Manager at Marshall Group. “Acton and Stanmore [are] chosen time and again for their iconic design, premium build quality, rich, powerful sound, and intuitive tactile controls,” Berber continues. “With our fourth generation, the focus has been on protecting and strengthening these core qualities, building on what people love rather than reinventing it.”

The Marshall Acton IV and Stanmore IV are available now and are offered in black and cream colorways. Both models are Auracast-enabled Bluetooth speakers in Marshall’s fourth-generation home speaker lineup. Acton IV pricing starts at $329.99 and Stanmore IV pricing starts at $429.99. Pricing is listed as starting at $329.99 for the Acton IV and $429.99 for the Stanmore IV, as published at launch.

The new models are compatible with Acton IIIs and Stanmore IIIs for combined multi-speaker setups. Auracast functionality enables multiple Acton IV and Stanmore IV units to play from the same source. The Marshall app provides expanded EQ controls and audio placement optimization for these speakers. RCA and AUX ports are located on the bottom of each unit to allow wall-friendly placement and to simplify connections to record players and other analog sources.
