ATC SCM40 Loudspeakers

Incorporating the new 25mm soft dome tweeter, ATC’s famous super-dome 75mm midrange transducer and the 165mm bass driver developed for the SCM35, the SCM40 offers an exceptionally wide-ranging, smooth and accurate mid-band response, together with a superbly extended and dynamic bass performance.

It also features an optional four part precision floor spike assembly for the hardwood base plate.

Manufactured in house to exacting tolerances, ATC’s drivers are legendary for their many design innovations. For instance, our hand-wound short voice coils use only high density edge-wound flat OFC wire and operate in a precision long magnetic gap.

Front and rear magnetic venting not only reduces airflow and noise, but increases power handling and long term reliability. Meanwhile, massive motor assemblies offer no-compromise optimisation for each voice coil diameter.

Customer Reviews:

The ATCs have the incontestable authority to take the song by the scruff of the neck and bring it bounding to life. The by no means easy trick of integrating all three drivers is pulled off with something approaching disdain, so the SCM40s enjoy crisp timing, an expansive, explicit soundstage, and fine stereo focus. Low frequencies are deep, taut and responsive, the midrange occasionally torrential in the amount of detail and expression it delivers, and percussives at the top end shine benignly. This winningly even and musical tonality is apparent whether playing small-scale, subtle recordings (when the ATCs sound like they’ve shrunk to the size of dextrous standmounters) or full-on orchestral blow-outs (when they sound big enough to fill a concert hall).

The SCM40's could play very loud without seeming to make excessive demands of any of the amplifiers I tried them with...On smaller scaled music, the SCM40s could get out of the way, if not quite disappear...The SCM40 is an almost amazing value for money.(US$4250) It's built in the UK by a company with as much heritage and credibility as you could ask for.
