Marshall Launches Acton IV and Stanmore IV Speakers with Customizable M-Buttons and Improved Audio

Marshall has officially unveiled its next-generation Acton IV and Stanmore IV home speakers, arriving four years after the previous models. The vintage-inspired speakers retain the brand’s iconic retro aesthetic while introducing several modern upgrades — most notably, customizable M-buttons that let users tailor their listening experience.

Available now in cream and black finishes, the Acton IV is priced at $300 and the larger Stanmore IV at $400.

Customizable M-Buttons

The headline feature of the fourth-generation lineup is the new M-button on the top panel, which users can customize to instantly trigger their most-used functions. Options include activating Spotify Tap to resume music playback, or switching to a preferred equalizer preset with a single press.

This personalization layer adds a new level of convenience, letting owners skip the app when they just want to jump straight into their audio.

Refined Design and Build

Both the Acton IV and Stanmore IV retain the signature look that has made Marshall speakers a staple in homes worldwide — cabinets constructed from 100% wood wrapped in PU leather, with an upgraded media jog dial and power switch that maintain the lineup’s analogue feel. The classic brass-toned control panel sits on top, now refreshed with the new customization features.

Better Sound, Better Coverage

Marshall has redesigned the tweeters and waveguides inside both speakers for the fourth generation, promising more even sound dispersion across larger rooms. The Stanmore IV, as the larger model, delivers a wider soundstage suited for living rooms and open-plan spaces, while the Acton IV is optimized for bedrooms, home offices, and smaller rooms.

Marshall promises more powerful bass and clearer, richer overall sound for both models compared to their predecessors.

Connectivity and Multi-Room Audio

The Acton IV and Stanmore IV come equipped with RCA input for connecting turntables and other analog sources, plus a 3.5 mm stereo AUX jack on the top panel for wired connections to phones, laptops, and media players.

On the wireless side, both speakers support Marshall’s Auracast technology, enabling multi-speaker setups where multiple Acton IV and Stanmore IV units can play in sync. For owners of older Marshall speakers, the company’s Heddon streaming hub (launched earlier this year) bridges the gap — it lets legacy speakers join the party. Heddon costs $300 standalone, or is available free when purchasing two or more eligible speakers from Marshall’s website.

Pricing and Availability

The Marshall Acton IV ($300) and Marshall Stanmore IV ($400) are available now from Marshall’s website and select retailers in cream and black colorways.

Whether you’re building a multi-room audio system or upgrading a single bookshelf speaker, the fourth-generation lineup brings meaningful improvements to an already beloved speaker family — blending Marshall’s classic rock-and-roll aesthetic with genuinely useful modern features.
