A Bluetooth speaker combining power and elegance
The Marshall Acton IV speaker embodies the perfect alliance between a vintage design inspired by the brand's iconic amplifiers and modern audio technology. Designed for music lovers and fans of immersive sound, it fits equally well in a living room or a workspace, delivering a rich and balanced sound experience suited to all everyday uses.
Optimized stereo sound for every space
The Acton IV stands out with its 10.16 cm (4-inch) woofer and its two 1.9 cm (0.75-inch) tweeters, all powered by Class D amplifiers (60 W for the woofer and 25 W for each tweeter), for a total power of 85 W. Thanks to its redesigned bass-reflex port and Dynamic Loudness technology, it delivers deep bass and clear highs, even at low volume.
The extended frequency response (37–38 000 Hz) and maximum sound pressure level of 95 dB SPL ensure an immersive listening experience, suited to the most dynamic tracks as well as relaxing atmospheres. Connectivity is enhanced with Bluetooth 5.3, 3.5 mm AUX and RCA inputs, as well as Auracast technology for wireless multi-speaker synchronization.
