Marshall Acton IV and Stanmore IV: Enhanced Home Speakers 2026

Marshall has just updated the two fundamental pillars of its home audio catalog with the launch of the Acton IV and Stanmore IV home speakers. These new models hit the market keeping that recognizable aesthetic inspired by classic guitar amplifiers, but introducing significant acoustic and technological improvements inside to meet today's demands.

Fourth-Generation Redesign: What's New in the Acton IV and Stanmore IV

The big bet of this fourth generation lies in the redesign of their internal architecture. Marshall has improved the tweeters and waveguides to project a notably wider and more defined soundstage, achieving homogeneous sound dispersion throughout the room.

This means that whether you're sitting directly in front of the speaker or moving around the room, you'll experience consistent audio quality without dramatic drop-offs in clarity or volume.

Bass-Reflex Port Optimization for Cleaner Low Frequencies

An intelligent change has been made to the bass-reflex port design. The airflow has been optimized to deliver cleaner low frequencies, reducing unwanted distortion and port noise.

Additionally, the cable output has been moved to the bottom of the base. This small but crucial detail allows you to place the speakers completely flush against the wall without affecting bass performance or causing unpleasant booming.

Dynamic Loudness Technology for Consistent Sound at Any Volume

To ensure sound balance regardless of volume, both models incorporate Dynamic Loudness technology. This system subtly adjusts frequencies automatically so that music doesn't lose body or warmth when listening at low levels. The longer history behind the story is traced in Marshall Acton IV and Stanmore IV: Enhanced Home Speakers.

Whether you're playing background music at a dinner party or cranking up your favorite track, the Acton IV and Stanmore IV maintain their sonic character.
