ATC SCM-20 Passive Bookshelf Speakers (pair)

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.
