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.

Key Features

• 1 x High-Frequency ATC 1”/25mm Dual-Suspension ‘S-Spec’ Tweeter
• 1 x 6”/150mm bass driver part with huge 3”/75mm voice coil
• Proprietary ‘SL’ motor technology
• High-voltage polypropylene capacitors
• 10 different hand-selected veneers
• 5-Year Warranty

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 a 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 a very high energy 2.1 Tesla motor.  Together, they form the basis for an exceptional 2-way monitor loudspeaker.  Integrating the drivers is a 2^nd order crossover featuring oversized 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 ensure excellent compatibility with a very wide range of quality electronics.

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

Who are ATC

Formed in 1974 by Billy Woodman to manufacture custom drive units for the professional sound industry, ATC quickly made its mark with the 12″ PA75-314 driver, a design capable of handling more power and producing less distortion at a higher sound pressure level than any other unit on the market. Having established a market for reference quality precision-made monitors, a succession of smaller ATC speakers then evolved, ranging from SCM7s through 10s and 20s. Available in both active and passive versions, they offered elite ATC performance and reliability to many new customers.

Through ATC’s commitment to multi-channel mastering and its direct involvement with leading players in the professional audio industry including Sony Music and Telarc, ATC’s products are installed at some of the world’s most prestigious multi-channel studios and auditoria. Where ever the best is required you will find ATC.
