The ATC SCM20 is ATC’s flagship 2-way stand-mount loudspeaker and is the ideal choice in modestly sized rooms, but where performance cannot be compromised.

Its sealed cabinet design ensures excellent timing, useful low frequency output below the cut-off and that the speakers can be placed relatively close to walls without excessive low frequency output or ‘boom’.

Both the mid-bass driver and tweeter are handmade by ATC.  The bass driver is a 6”/150mm part with huge 3”/75mm voice coil and massive, long-gap (short-coil) motor assembly featuring ATC’s proprietary ‘SL’ motor technology.  The tweeter is a 1”/25mm soft-dome part featuring a dual-suspension and very high energy 2.1 tesla motor.  Together, they form the basis for an exceptional 2-way monitor loudspeaker.  Integrating the drivers is a 2nd order crossover featuring oversize air-core inductors which are wound in-house by ATC.  Capacitors are all high voltage polypropylene film types which deliver outstanding reliability and minimal losses.

The SCM20 cabinet is constructed to be heavy and inert, with bitumastic damping panels deployed at critical positions to minimise cabinet colouration.  The cabinets are available in 10 different hand selected veneers; satin black/white painted finishes and also piano/white high gloss polyester.

The passive SCM20 are ideally paired with ATC pre/power/integrated amplifiers.  However, their neutral fidelity, outstanding resolution and modest load impedance also ensures excellent compatibility with a very wide range of quality electronics.

Upgrading performance and offering a reduced ‘box count’ he SCM20 is also available as a bi-amplified active floor-stander in the form of the SCM20ASLT.

No Substitute for In-House Engineering and Manufacturing

Found in many of the world's finest recording studios and soundstages, and used by dozens of the most acclaimed producers and engineers in the music and film industries, ATC loudspeakers claim an unparalleled reputation. Focused on applying supreme engineering to proven audio principles, the tradition-minded British company produces English-made speakers revered for their revealing nature, astonishing clarity, and exceptional balance. Tested and assembled in-house, its famous drivers and tweeters are exclusive to ATC – you won't find them on any other brand. And unlike most manufacturers, ATC still constructs midrange domes to supply breathtaking coherence. The rest of the rationale follows: If ATC is good enough for studio pros such as the late Doug Sax and superstar artists like the Rolling Stones, they're good enough for you.
