The Acton III is Marshall's mid-size home Bluetooth speaker, built around a 60 W class D amplifier driving a woofer and two tweeters in a sealed wooden cabinet. It stands out for its guitar-amp styling, physical treble and bass knobs, and a wide 45 Hz to 20 kHz range that gives it more low-end weight than most speakers its size. It is mains-powered only, with no battery, Wi-Fi, AirPlay or multiroom, so it suits a shelf, desk or sideboard in one room rather than a portable or whole-home setup. Owners rate it highly for sound and looks; the main trade-offs are its size, its dependence on a wall outlet and the fact that it is a single-speaker unit.
