Marshall Acton III Home Bluetooth Speaker (Black)

The Acton III is the smallest speaker in Marshall's mains-powered home range: built to sit on a shelf or a desk rather than be carried. It keeps the amplifier look: the vinyl-textured wrap, the script logo and three analogue knobs for volume, bass and treble.

Because it plugs into the wall rather than running off a battery, it can hold a higher output continuously than a portable of the same size. Marshall rate it at one 30 W woofer channel and two 15 W tweeter channels, all Class D.

What to confirm before you order

• Details we could not verify for this model: driver sizes, maximum spl. We would rather tell you we do not have them than print a number we cannot stand behind.
• Read from Marshall's own specification table. One thing a buyer should know: Marshall replaced the Acton III in July 2026 with the Acton IV, which adds Auracast multi-speaker connectivity, upgraded tweeters and waveguides, and a redesigned bass port. The Acton III remains in Marshall's range and is not discontinued stock, but it is the previous generation and it is fair that the price reflects that. On the amplification: Marshall publish one woofer channel and two tweeter channels, which is what the table above says. They publish no driver sizes for it, so none is given. No warranty term is stated on this page, because the manufacturer does not publish one for Pakistan. Whatever cover comes with this unit is ours rather than theirs, so ask us what it is and how long it runs, and get the answer in writing, before you order.
