Marshall Acton IV Bluetooth Home Speaker

Marshall Acton IV — Compact Home Speaker, Wider Sound, Deeper Bass

The fourth-generation Acton brings Marshall's iconic amp-inspired design to a compact Bluetooth home speaker with a wider stereo soundstage, a redesigned bass port for cleaner low end, and built-in Auracast™ so it slots straight into a multi-speaker set-up.

Key Features

• Wide soundstage: Upgraded tweeters and waveguides spread sound across a bigger area with improved stereo separation.
• Enhanced bass: Redesigned bass port delivers cleaner, more powerful bass that stays tight at high volume — and lets the speaker sit flush against a wall.
• Dynamic Loudness: Tonal balance adapts automatically so music sounds full at any volume.
• Multi-speaker connectivity: Auracast™ receiver — play in sync with other Auracast™ Marshall speakers or a Heddon hub.
• Customisable M-button: One press for Spotify Tap or your saved EQ preset.
• Analogue inputs: RCA input for turntables (pre-amp required) plus 3.5 mm AUX.
• Marshall app: EQ presets, room calibration and settings.
• Tactile brass controls: Bass, treble, volume, media jog, source and the signature power switch.
