Marshall Acton III Bluetooth Home Speaker - Black

Marshall Acton III in Black is a compact Bluetooth home speaker that delivers big, room-filling stereo sound without taking over your shelf. With 60 watts of total Class D amplification, a re-engineered wider soundstage and the unmistakable Marshall amp-inspired look, it is built for listeners who want real sound character and real style in the same object.

In under a minute: it is the most compact speaker in Marshall's home line-up, powered from the wall, with Bluetooth 5.2, a 3.5 mm input and bass, treble and volume knobs on the top panel. Pair it, press play, turn it up.

Why It Stands Out

• Wider stereo soundstage: outward-angled tweeters and updated waveguides are designed to spread sound further across the room.

• Sound that adapts to volume: Dynamic Loudness adjusts the tonal balance so music stays full and detailed whether you listen softly or loudly.

• Iconic design: the Marshall script and brass control knobs give it the look of a classic amp in a modern home-audio package.

• Hands-on control: adjust bass and treble directly on the speaker, with no need to open an app for every tweak.

Key Features & Benefits

• 60 W total power: one 30 W Class D amplifier for the woofer plus two 15 W Class D amplifiers for the tweeters, for confident volume in everyday living spaces.

• Bluetooth 5.2 and 3.5 mm input: stream wirelessly from your phone or tablet, or connect a wired source such as a laptop or TV.

• Top-panel controls: source button, volume knob, bass knob, treble knob, play/pause button, skip control and power switch.

• Marshall Bluetooth app: access advanced settings, Placement Correction and Over-the-Air (OTA) updates to keep the speaker current.

• Frequency range: 45 Hz to 20,000 Hz, with stereo audio output.

• Compact footprint: 260 x 170 x 150 mm (10.24 x 6.69 x 5.91 in), small enough for a bookshelf, desk or sideboard.

• Thoughtful materials: a PVC-free build with 70% recycled plastic and vegan materials, according to the product information provided.

Real-World Applications

• A statement speaker for a living room, studio apartment or home office.

• Everyday playlists, podcasts and streaming from your phone over Bluetooth.

• A simple audio upgrade for a TV or laptop through the 3.5 mm input.

Who Is It For?

Music lovers, design-conscious buyers and anyone who wants an easy, good-looking home speaker with the Marshall sound signature. It also suits gift buyers looking for a recognizable, premium audio brand.

What to Know Before Buying

Final Buying Perspective
