Description
Marshall Acton III
The Marshall Acton III Bluetooth speaker blends vintage Marshall styling with home-friendly wireless playback, a re-engineered wider stereo soundstage, and straightforward pair-and-play setup for rooms from quiet listening to gatherings.
Sound
A 3-class D amplifier drives dual tweeters and a subwoofer for immersive Marshall signature sound with deep bass, clear mids, and crisp highs. Top-panel analog knobs adjust volume, bass, and treble. Despite a compact footprint, the Acton III projects a wide soundstage to fill a room.
Connectivity
- Next-generation Bluetooth 5.2 for wireless streaming from phones, tablets, and computers
- Multi-host pairing: connect two source devices and switch between them without constant re-pairing
- 3.5 mm auxiliary input for wired listening
Generation III hardware is built to adopt future Bluetooth features as they become available.
Design & materials
Classic Marshall cues include textured vinyl, salt-and-pepper fret, script logo, metal grille, and gold-toned control knobs. The home lineup uses a PVC-free build with about 70% recycled plastic and vegan materials only.
Use & limitations
Water resistance: Not waterproof—intended for indoor use.
Multi-room: Does not support pairing multiple Acton III speakers for multi-room; multi-host covers two source devices, not stereo pairing of two speakers.
Voice assistants: Compatible with Alexa and Google Assistant for convenient voice control when paired with supported setups.
Setup
Plug in, pair over Bluetooth or connect via AUX, and use the analog controls to dial in level and tone. A user manual guides initial setup.
