Marshall Acton IV and Stanmore IV Review: Style-Forward Wireless Sound for the Home

Verdict: Beautiful Bluetooth speakers for style‑conscious listeners

The Marshall Acton IV and Stanmore IV are vintage‑styled home audio speakers that pair classic guitar‑amp aesthetics with modern Bluetooth connectivity and upgraded acoustics for listeners who care as much about décor as sound quality. At their core, these are compact home audio speakers built to sit in living spaces, offer strong room‑filling performance, and double as statement pieces rather than anonymous black boxes. Bottom line: they sound confident, look fantastic, and feel premium to use, but they lean on Bluetooth and wired inputs instead of Wi‑Fi, so they suit people who value tactile controls and visual flair over multi‑service streaming cleverness. At USD 300 (approx. RM1,380) for the Acton IV and USD 400 (approx. RM1,840) for the Stanmore IV, they are priced against more connected rivals, yet remain compelling for style‑led buyers who want Bluetooth speakers with vintage design and solid sound.

Design and controls: Vintage amp looks, modern usability

From a design standpoint, the Acton IV and Stanmore IV are textbook Bluetooth speakers with vintage design, borrowing heavily from Marshall’s guitar amps. Both use 100 percent wood cabinets wrapped in PU leather, with a brassy logo on a front mesh grille edged in brass, and a rectangular silhouette that looks deliberate rather than generic. Rubber feet keep the speakers planted, while the underside hides the woofer and discreet ports for power and RCA inputs, helping them blend cleanly into shelves or sideboards. The top control panel is the star: a recessed strip holds a 3.5 mm AUX input, source‑select button with indicator lights, dedicated dials for volume, bass and treble, a jog button for playback, and that delightfully chunky power switch that many will find addictive to flick on and off. This layout makes these home audio speakers feel physical and approachable in a way touch panels rarely match.

Features and connectivity: Bluetooth‑first, with Auracast and custom M‑buttons

Feature‑wise, Marshall’s focus is on improved Bluetooth and smarter local controls rather than cloud services. Both the Marshall Acton IV and Stanmore IV speakers add Auracast support, indicating a newer Bluetooth stack and allowing you to play the same music across multiple units without complex setup. This gives you a simple multi‑room or party solution, especially if you own several of these home audio speakers. A pair of customizable M‑buttons can be programmed to instantly trigger Spotify Tap or recall favorite EQ presets, turning the speakers into one‑press mood machines rather than forcing you into app menus. Wired connectivity is covered through RCA inputs on the rear and a 3.5 mm AUX jack on the top, making them friendly to turntables and legacy players. However, the lack of any Wi‑Fi, AirPlay 2 or Spotify Connect means streaming is tied to your phone or laptop, which feels like an intentional but limiting choice at this price.

Sound quality: Wide soundstage and lively, adjustable tuning

Marshall claims that redesigned tweeters and waveguides give the Acton IV and Stanmore IV a wider sound dispersion and more powerful bass with clearer, richer tones, and in use the Acton IV delivers on that promise. During a couple of weeks of listening, Bluetooth connectivity proved stable, with no drop‑outs or pairing drama. The Acton IV punches above its size, filling small and medium rooms with ease and acting as a credible single‑box solution when space is tight. Acoustic tracks, such as Django Django’s “Cameos,” come through with engaging warmth and clarity, while more aggressive material from Queens of the Stone Age or Justice shows off the brand’s taste for loud, slightly gritty rock‑friendly sound. The physical EQ knobs invite more experimentation than typical app sliders: adjusting bass and treble is smooth and immediate, with the volume dial’s fine gradations giving precise control over loudness. Stanmore IV, with its larger cabinet, extends this character to bigger rooms and higher listening levels.

Price, competition and who they’re for

The Acton IV is available now at USD 300 (approx. RM1,380), while the larger Stanmore IV comes in at USD 400 (approx. RM1,840), both in cream or black finishes. Notably, Marshall held prices steady compared to the previous generation in some markets, despite these acoustic and connectivity tweaks. At this level, many rival home audio speakers offer Wi‑Fi, AirPlay 2 or Spotify Connect for more flexible whole‑home listening, which makes Marshall’s Bluetooth‑only stance feel conservative. On the other hand, that simplicity is part of the appeal: there is less setup, fewer accounts to manage, and no cloud‑service dependence. According to one review, "the Acton IV is another great speaker release from Marshall," praised for consistency but also described as lacking ambition for omitting Wi‑Fi. If you want Sonos‑style streaming ecosystems there are better options, yet if you want Bluetooth speakers with vintage design and tactile satisfaction, these are hard to beat for a style‑forward living room.
