We conducted an extensive sound test to find out.
Design and Build Quality
The Marshall Acton III features a vintage-inspired design reminiscent of classic guitar amplifiers. Its sturdy construction is made from high-quality materials, giving it a premium feel. The compact size makes it easy to place on a desk or bookshelf without taking up much space.
Sound Performance
During our sound test, the Marshall Acton III impressed with its rich, warm tone and clear bass. Despite its small size, it produces a volume that fills a room without distortion. The speaker’s three Class D amplifiers efficiently power the woofer and tweeters, delivering balanced sound across the frequency spectrum.
Bass and Treble
The bass response is surprisingly deep and punchy for a small speaker. Treble frequencies are crisp and detailed, making vocals and instruments sound lively and authentic. The sound remains clear even at higher volumes, which is a testament to its quality engineering.
Soundstage and Clarity
The soundstage is wide, providing a sense of space that enhances listening experience. Clarity is maintained across different genres, from classical to modern pop, without any muddiness or harshness.
Connectivity and Features
The Marshall Acton III supports Bluetooth 5.2 for seamless wireless connection. It also includes an auxiliary input for wired devices. The control knobs for volume, bass, and treble allow users to customize sound to their preference. A dedicated app provides additional settings and firmware updates.
Comparison with Competitors
Compared to other small speakers like the Bose SoundLink or Sonos One SL, the Marshall Acton III offers a more vintage aesthetic and a warmer sound profile. While some competitors may have more advanced smart features, the Acton III excels in delivering high-quality audio in a compact form.
