What it is

The Marshall Stanmore III successfully bridges the gap between vintage guitar amp aesthetics and contemporary high fidelity audio. Positioned as the mid sized anchor of Marshall's home lineup, this speaker delivers a surprisingly wide soundstage thanks to outward angled tweeters and updated waveguides. It maintains the physical tactile knobs for bass and treble that enthusiasts love, allowing for immediate acoustic adjustments without digging through a smartphone app. Constructed with a PVC free build using 70 percent recycled plastic, the Stanmore III feels robust and premium despite its shift toward sustainable materials. While it lacks a battery for portable use, its inclusion of RCA and 3.5mm inputs makes it a versatile hub for home entertainment. You can easily toggle between a modern Bluetooth 5.2 stream from your phone and a classic wired connection from a vinyl record player, making it a functional centerpiece for any room.

Ravvy AI insight

The Stanmore III offers the best price to performance ratio in Marshall's current lineup, providing significantly more depth than the Acton without the massive footprint of the Woburn. Its support for Bluetooth LE Audio makes it a safer long term investment than older models, ensuring better sync and stability as new devices launch.

How to get the most out of it

Placement for Best Sound

Position the speaker at ear level and at least six inches away from walls. The rear firing port needs space to breathe to prevent the bass from sounding muddy or distorted.

Ownership tips

Vinyl Player Connection

Use the RCA inputs on the back to connect your turntable. If your record player does not have a built in preamp, you will need to add one in between the player and the speaker.

care

Cleaning the Grille

Use a soft, dry brush or a vacuum with a brush attachment to remove dust from the fabric grille. Avoid using wet cloths as they can trap moisture in the textured weave.
