Marshall Stockwell III returns after 7-year break with major upgrade

Since the launch of its predecessor, a lot has changed on the technical side, and the series is now being brought up to current standards. Similar to its larger Bromley lineup, the more compact Stockwell III can now be positioned more flexibly, enabled by true 360-degree omnidirectional sound.

It also plays for twice as long, with battery life rated at over 40 hours of playback.

On the audio side, the Stockwell features a 3-inch woofer and two 1.75-inch full-range drivers, each powered by dedicated Class D amplifiers. The woofer is driven by a 65 W amp, while the full-range drivers are powered by two 31 W amplifiers. Frequency response is rated at 54 Hz – 20 kHz, with a maximum sound pressure level of 86 dB at 1 meter.

One of the key upgrades is the IP55 certification, giving the Bluetooth speaker much stronger resistance against dust and water, making it far more suitable for outdoor use.

And when your smartphone starts running low while streaming, it can be charged via USB-C using the speaker’s battery.

As expected from Marshall, tactile controls remain a major highlight. While competitors rely on flat push buttons, the new Stockwell features larger brass dials that can be rotated.

A likely configurable M button provides quick access to presets, while a dedicated media control button allows users to skip tracks and navigate playback.

Despite being announced on June 9, buyers will need to wait a bit longer. The Stockwell III will be available starting August 18 for €229 on marshall.com, followed by availability at selected retailers from August 25.
