ATC SCM 150 SLT Active

• The broad-shouldered British speaker let us feel this efficiency from the very first second when Ray Brown's masterpiece "Soular Energy" or "That's all Piano" with Gene Harris played. It was a performance that awakened memories of accelerations previously only experienced in supercars, only to bring the shimmering impulses to a complete stop in the next moment. Brown's double bass stood large and voluminous – though without the slightest inclination to drone – as well as vivid in height, stage width and depth and yet sharply outlined in front of the audience.
• Belafonte at Carnegie Hall showed all facets of this extraordinary singer and entertainer and the "Cotton Fields" made you forget that the recording was made in 1959. The passion with which the American, subtly but effectively supported by the bass, performs his songs is simply impressive.
• If you've always wanted to hear a clarinet, "El Choclo" and "Maria", played by Giora Feidman, captured live in a New York church, with their gentle, almost tender wind sounds, are the ideal introduction, especially since the guitar sounds played along with them are perfectly integrated.
• Verdict: A three-way active loudspeaker in a class of its own. The ATC SCM 150 A SLT hides most sophisticated technology behind its rather simple exterior. With its perfect neutrality in tone, crazy dynamic reserves and deep, dry bass foundation it is just as convincing as it is with its precise spatial imaging.

• Despite their size they are remarkably easy speakers to accommodate inasmuch as they are not as fussy about placement as the average large passive design. Specifically you can put them quite close to a rear wall and, room shape allowing, this doesn’t result in exaggerated bass.
• Play a few more pieces and you discover that they merely reflect the original balance with greater accuracy than usual and that some recordings have considerably more low end on them than others.
• It’s worth noting that my listening room is not very wide, 3.5m for the most part, yet on this system never is there any sense of the bass being too much. Even with less than 50cm to rear walls, and not a lot more to the sides, the bass is very tidy and controlled.
• The new tweeter is a boon as well, as it’s more revealing yet sweeter than the SEAS unit it replaces. This speaker used to be a bit 'warts an' all' for anything less than smooth, clean electronics and recordings, but the tweeter has made the 150 a whole lot more charming without losing transparency.
