Wider stereo + Dynamic Loudness — what this means in your room
The Stanmore III's angled tweeters point outward rather than straight forward — the high-frequency drivers are physically aimed to widen the stereo field beyond the speaker's own footprint. Combined with updated waveguides that shape how sound disperses from the driver, the result is a soundstage that feels wider than the speaker itself — you hear separation between instruments and vocals even when sitting off-axis. Dynamic Loudness addresses a classic problem with home speakers: at low volumes, the human ear perceives less bass and treble relative to midrange (the Fletcher-Munson curve). Dynamic Loudness compensates by automatically boosting lows and highs at lower volumes — so your 7am background music sounds full-bodied, not thin and tinny.
Built with the environment in mind: 70% recycled plastic body · PVC-free exterior (PVC is difficult to recycle and releases harmful compounds when manufactured) · vegan-friendly materials (no animal-derived adhesives or dyes). Same Marshall sound — meaningfully lower environmental footprint.
BT 5.2 delivers improved audio quality, better range, and lower latency than 5.0. OTA updates via the Marshall app means the speaker's firmware improves over time — bug fixes, new features, and codec support added without buying a new unit. Future-ready rather than frozen at launch.
Dedicated physical controls for volume, bass, treble, Bluetooth pairing, and power. Adjust the bass while music is playing without unlocking your phone. The tactile knobs are part of Marshall's identity — they also mean the speaker is fully usable without the app or a smartphone at all.
A powered speaker with RCA input is relatively rare at this price point. Connect a turntable directly for vinyl playback without a separate amplifier. Or connect a CD player, TV, or any hi-fi source. The Stanmore III works as a powered monitor in a proper audio chain.
97 dB SNR means the audio signal is 97 dB louder than the noise floor — at normal listening volumes, background hiss is effectively inaudible. Relevant when you use the RCA or aux input with sensitive sources: you won't hear ground noise or hum during quiet passages.
