SCM20
Overview
The SCM20PSL 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.

The stand-mount and compact passive SCM20SL loudspeaker.
The compact SCM20SL reproduces bass with remarkable articulation and authority, combined with outstanding mid-band clarity and incredible dynamic range.
Drawing strongly on ATC’s professional audio experience, this hybrid design incorporates a 150mm bass cone on to which is grafted a 75mm soft dome. The magnet assembly utilises ATC’s unique “SL” technology which greatly reduces distortion in moving coil drive units by a very significant 12-15dB (3rd harmonic). To minimise Time Domain Distortion both dome and cone are made from acoustically “dead” polyester wave material doped with ATC’s own formulation.
