Wide soundstage
Improved tweeters and waveguides help spread your favourite music across larger area of the room. Enhanced stereo separation creates more expansive listening sessions, bringing you closer to the music you love.
Enhanced bass
Hit play and let the whole room feel the bass. A redesigned bass port creates a cleaner and more powerful bass with tighter sound at higher volumes. It's also easier to place the speaker flush against walls.
Dynamic loudness
When listening habits can change from day to day, Acton IV's tonal balance is adapted to ensure your music sounds incredible at every volume. Enjoy a consistent, clear, and composed sound you can rely on.
Customisable M-button
Of course the fourth edition of Acton had to feature the M-button. Instantly adjust the sound to match your listening needs or dive straight into your favourite music via Spotify Tap. All it takes is one press.
Take a closer look
Get closer to the songs you love thanks to a wider, more even sound throughout the room and cleaner, more powerful bass. Highlighted below are the key components behind the refined acoustic performance.
Use the heritage amp-inspired controls to easily adjust volume, bass, and treble and manage your music playback. The classic brass top panel includes an improved media control and the signature power switch.
Connect your record player and fill the room with classic vinyl sounds using the new RCA input. Or bring in other audio devices by making the most of the AUX input and a 3.5 mm stereo jack lead.
Tailor the sound to fit your mood, whether you're playing the music that inspires you or listening to a podcast. Adjust EQ settings and use placement compensation to achieve the perfect acoustic fit for your space.
