The Marshall Acton III blends classic analogue craftsmanship with modern acoustic engineering, delivering powerful stereo sound in a compact frame. Built to enhance every room with immersive music, it brings together heritage design, superior sound balance, and effortless connectivity for everyday listening.

Redesigned for a Wider Soundstage

Precision-engineered to project a wider stereo soundstage, the Acton III immerses you with Marshall’s signature room-filling audio. Updated waveguides and outward-angled tweeters create a balanced acoustic footprint, reaching every corner with clarity and controlled bass for a concert-like experience.

Instant Pair, Play and Control

Enjoy a seamless start-up experience—just pair and play without complicated setups. Physical knobs for volume, bass, treble, and power let you fine-tune your sound directly on the speaker, while easy-access buttons allow instant Bluetooth pairing and playback adjustments.

Timeless Rock ‘n’ Roll Design

With its retro-inspired finish, brass accents, and iconic Marshall script logo, the Acton III stands out as both a décor piece and a sonic powerhouse. Available in Black, Cream, Brown, Midnight Blue, and Burgundy, its premium texture and minimalist styling embody the true spirit of sound and style.

Next-Gen Bluetooth and Connectivity

Featuring advanced Bluetooth 5.2 with readiness for LE Audio, plus a 3.5 mm wired input, the Acton III ensures stable connections with clear, low-latency sound. Manage updates and audio customization via the Marshall Bluetooth app, which supports OTA (Over-the-Air) software updates for future enhancements.

Premium Audio Hardware Setup

A robust internal amplifier system powers every beat with precision — including one 30W Class D amp for the woofer and two 15W Class D amps for the tweeters. With a frequency range of 45–20,000 Hz and up to 95 dB SPL at 1 m, it provides full-bodied sound suited for both small and medium rooms.
