Acton

Marshall has just updated the two fundamental pillars of its home audio catalog. The new ones Acton IV and Stanmore IV They arrive on the market keeping intact that recognizable aesthetic inspired by classic guitar amplifiers, but introducing important acoustic improvements and technologies inside to adapt to current demands.

Marshall has improved the tweeters and the waveguides with the aim of projecting a noticeably wider and more defined sound scene, achieving a homogeneous dispersion of sound throughout the room. Added to this is a very intelligent change in the bass port design (bass-reflex). Airflow has been optimized to deliver cleaner low frequencies. In addition, the cable exit towards the bottom of the base has been modified. This small aesthetic and functional detail is key: it now allows you to place the speakers completely against the wall without affecting the bass performance or causing unpleasant rumble. To guarantee sound balance regardless of volume, both models incorporate the technology Dynamic Loudness. This system subtly adjusts the frequencies automatically so that the music does not lose body or warmth when we listen to low levels, and avoids distortions thanks to improved limiters when we decide to squeeze its power to the maximum. Auracast connectivity and nods to the analog world In the technical section, the great novelty is the integration of the Auracast technology. Thanks to it, it is possible to natively synchronize several Acton IV and Stanmore IV speakers throughout the house to create a multi-room audio system. Even the previous generation models (Acton III and Stanmore III) can add to this experience by Heddonthe brand’s new transmitter device and streaming hub. Despite its wireless aspect and its renewed control app, Marshall does not forget lovers of physical formats. In the back we find RCA analog inputs and a 3.5mm AUX portmaking them perfect companions for plugging in a turntable for a full analog experience in the living room. Sustainable and repairable design True to its identity, the top panels maintain the classic brass analog controls to manage volume, bass and treble intuitively. However, the brand has added a Fully customizable “M” button which allows you to activate quick functions such as Spotify Tap or switch between your favorite equalizations with a single touch. Finally, the firm wanted to take a step towards sustainability. The boxes are made from 100% FSC certified MDF wood and incorporate a percentage of recycled materials in their construction (13% in the Acton IV and 16% in the Stanmore IV). In addition, a modular structure oriented towards repairability has been designed, allowing easily replace wearing parts such as the legs, the physical controls or the front grille itself.
