With the new Acton IV, Marshall proves once again how iconic design can coexist with cutting-edge acoustics. Every detail in this new version has been perfected, delivering a room-filling stereo sound thanks to redesigned tweeters and sophisticated waveguides, which disperse the music evenly, creating a wider soundstage with exceptional depth and realism. The redesigned aerodynamic bass port ensures clear, powerful, and tight bass even at high volumes, while the clever cable routing at the bottom allows you to place the speaker flush against the wall without any loss in performance. At the same time, the tonal balance adjusts automatically, ensuring that the music retains its clarity, richness, and warmth at any volume, while improved limiters prevent distortion. Thanks to built-in Auracast™ technology, you can now sync multiple speakers, leaving behind the endless pairing processes.The addition of the brand-new M-button offers instant access to your favorite playlists via Spotify Tap or to your custom EQ settings with a single press. The strong connection to Marshall’s amplifier heritage is evident in the classic brass top panel with its signature power switch and analog controls. For even greater flexibility, the AUX inputs and the new RCA input let you connect everything from simple audio devices to your turntable, filling the room with the authentic character of vinyl. Finally, the exclusive Marshall app simplifies management, offering everything from room calibration for perfect acoustic tuning to control over the brightness of the display.
