The Marshall Acton III Bluetooth Home Speaker is the smallest member of Marshall’s home speaker lineup, but it fills a room with a wide, full stereo soundstage. Its two-way driver system pairs outward-angled tweeters with updated waveguides to spread crisp treble and deep bass across a larger listening area than you’d expect from a speaker that measures just over ten inches wide. It’s a plug-in unit, not battery powered, so it stays put on a shelf, desk, or countertop as a dedicated home audio source.
You can get the Marshall Acton III Bluetooth Home Speaker on Amazon for just $200, down from its usual $300. That’s a $100 discount and 33% off.
A reliable portable speaker fit for a rockstar
The Acton III’s Dynamic Loudness feature automatically adjusts the tonal balance so music stays full and clear whether the volume is low or cranked up. Placement Compensation corrects for reflections from nearby surfaces, so you don’t need to worry about positioning the speaker away from walls or corners to get clean audio. You don’t have to worry about tuning these features, either. They both run in the background independently.
All the physical controls sit on top of the speaker. You get a power switch, a Bluetooth pairing button, dedicated bass and treble knobs, and a control knob for volume. There’s no need to reach for your phone to tweak the sound, though the Marshall Bluetooth app adds extras like over-the-air firmware updates and remote control if you want them. Two Acton III speakers can also be paired together in either ambient mode, where both play the same audio in sync, or stereo mode for a left-right split.
Bluetooth connectivity is via Bluetooth 5.2, while wired connections are limited to a 3.5mm auxiliary input. RCA inputs aren’t included in the design, so all wired audio inputs have to be routed through the 3.5mm auxiliary input. The speaker can use 100-240 volt AC power supply options that cover nearly every wall outlet worldwide, and the packaging includes the product itself, a mains power lead, and some user instructions.
Marshall gave the Acton III a cleaner version of its classic amp-inspired look, with a stripped-back exterior available in Black or Cream. The build uses PVC-free materials, 70% recycled plastic, and only vegan components.
For $200, the Acton III offers an excellent-sounding, high-quality home speaker with Bluetooth 5.2, onboard tone adjustments, and a classic Marshall style, all at a lower price than the usual $300 MSRP. It’s a plug-in speaker that doesn’t chase portability. That single focus on home audio keeps the sound quality and feature set tight for what it costs.
