Performance

The Marshall Acton III truly shines where it matters most: sound quality. Despite its relatively compact footprint, this speaker delivers a surprisingly potent and room-filling audio experience. The signature Marshall sound profile is immediately evident – a warm, rich bass that doesn’t overwhelm the mids and highs, producing a balanced and energetic output. Vocals are crisp and well-defined, while instruments retain their distinct presence, creating an engaging listening session across various genres.

Thanks to the improved tweeters and updated waveguides, the Acton III boasts a noticeably wider soundstage compared to its predecessor. While it’s a single-unit speaker, it manages to project sound with an impressive sense of space, making music feel less localized. The Dynamic Loudness feature is particularly effective, ensuring that clarity and depth are maintained whether you’re listening at a whisper or cranking it up to party levels. Bluetooth 5.2 connectivity is rock-solid, providing quick pairing and a stable connection without dropouts.

The tactile experience of the physical control knobs is a pure joy, offering a direct and satisfying way to tweak your audio settings on the fly. This old-school approach complements the speaker’s aesthetic perfectly, making interaction as much a part of the experience as the sound itself.
