ATC SCM 40 Floorstanding Speaker

The studio recording of Wagner’s “Lohengrin” presented the ATC SCM 40 ((3400 Euro, Paarpreis) with more neutral as the voluptuous tone colors, while she conjured up a wide space, almost like a real stage.)

Professionals from tradition

Among the organizations which carry the abbreviation ATC – from a University of up to military special task forces – the British loudspeaker manufacturer in business directories or on Google could nearly end. Where ATC is easy for acoustic transducer company, so manufacturers for Acoustic transducers. For many years focused on active Studio monitors. Mastering and producer legends like Bob Ludwig and Peter Walsh swore as well as the venerable BBC on the like boxy and often unusually expensive speaker in Gloucestershire, southern England. The most Hi-Fi fans, however, that the British have passive standing speakers with good value in the portfolio for quite some time, remained hidden.

The classic giant dome acts in the SCM 40, a classic 3-way passive box, as pure midrange of 380 3500 Hz up to and assumes important frequencies, the so-called Formant area that seamlessly all the timbre and vocal colorings. Deeper she can’t play, later not to due to the growing equity bundling – it is driven outside by a large 7.6 cm coil as each dome. A single inch dome, which is like its big sister with a light sound lead to the homogenization of the dispersion behavior takes the brilliance – and high-frequency range. Bass and tone may manage a relatively compact 17, playing without bass reflex enclosure. According to company founder Billy Woodman, a similarly precise and dry bass fits transparent middle which in turn is a philosophy?

Natural high

“Dry” in this context does not “powerless” means the SCM 40 proved impressively. But only when the editors had made similarly authoritarian power amplifiers. Because weak amplifiers or even tubes, the ATC acted clearly to delicate and little dynamic. It belonged to the nature effect, obsessed on dynamic speakers not even with appropriate lighting, but played mainly with an incredible naturalness in the heart of the editors. The studio recording of Wagner’s “Lohengrin” presented them with more neutral as the voluptuous tone colors, while she conjured up a wide, staged perfectly into the depths of space, almost like a real stage.

Particularly impressed the transparent and incredibly realistic in the space representation of the voices of that although in comparison with the KEF XQ 40 lost something on locating sharpness, but always also something for free and open tinged. Just quite Studio monitor worked the ATC something more, pop music, and was the typical Photocopied and crisp percussive album “piece by piece” by Katie Melua as dar as it exists on tape or CD. But in contrast to other monitors ever said to the property of acoustic magnifiers that also this Act always by free-sounding voices and a typically British respect the artist compared to was marked.
