Design and Tactile Experience

Marshall continues to lead the mainstream audio market when it comes to physical controls. With the launch of the Acton IV, the company reinforces its reputation for creating hardware that feels as good as it sounds. The design remains largely consistent with its predecessor, maintaining that signature rock-and-roll aesthetic that fits seamlessly into both vintage and modern interiors.

The unit features a classic rectangular silhouette, wrapped in a textured, faux-leather finish, and is fronted by a durable mesh adorned with the iconic brass Marshall logo. The top panel houses a recessed area for its hallmark physical controls:

  • Connectivity: A 3.5mm jack for wired input and a source-switching button with clear status indicators.
  • Sound Tuning: Three precision dials for master volume, bass, and treble adjustments.
  • Media Controls: A rocker-style switch for track management and a multi-function button for Auracast pairing.
  • Power: A satisfying, high-quality power toggle that remains the highlight of the user experience.

Connectivity and Modern Features

The most significant technical update in the Acton IV is the inclusion of Auracast, signaling an upgrade in its Bluetooth capabilities. While the connection remains rock-solid and reliable throughout daily use, the speaker keeps things simple by relying primarily on Bluetooth and wired connections.

For those looking for more control, the Marshall companion app is intuitive and well-designed, allowing for deeper customization of the physical "M" button. However, in an era where many competitors offer Wi-Fi connectivity to support platforms like Apple AirPlay 2 and Spotify Connect, the absence of network features feels like a missed opportunity for a home-based speaker.


Sound Performance

Marshall claims the Acton IV delivers a wider soundstage than previous iterations, and in practice, the speaker performs impressively for its compact footprint. It effectively fills small-to-medium rooms with rich, powerful audio.

«The rawness and grit of more aggressive production styles are handled with impressive clarity, yet the speaker remains equally capable of delivering warmth and detail in acoustic recordings.»

The integration of physical EQ knobs adds a layer of enjoyment that software-only solutions often lack. The precision of these dials—particularly the volume knob, which offers granular lighting feedback—allows for a highly personalized listening experience. The tactile feedback reinforces the sense of quality that Marshall has built its brand on.


Final Verdict

The Acton IV is a consistent and reliable follow-up in the Marshall lineup. It excels as a high-quality Bluetooth speaker with a design that justifies its price through sheer build quality and aesthetics. While it may lack the broader ecosystem flexibility offered by rivals like the Sonos Play or the multi-room capabilities of the Denon Home 400, it remains a fantastic choice for users who prioritize simplicity, style, and a straightforward, powerful listening experience.
