Studio Proven Technology

The ATC SCM40A Loudspeaker has three amplifiers to power each driver individually in the enclosure with a 150W module for the bass, 60W for the midrange and a 25W amplifier for the tweeter. The top plate of the tweeter’s 1.5 tesla neodymium magnet is heat-treated to disperse heat away from the voice coil maintaining high power handling and low power compression.

Featuring 25mm soft dome HF unit and precision alloy wave guide, they have a heavy build and take advantage of ATC’s meticulous engineering and studio-proven technology.

Award Winning Sound Quality By ATC

All drive units include large optimised motor assemblies and the soft dome mid-range driver and 164mm short coil bass driver produce superb audio quality and a punchy bass. ATC uses active operation, where power amplifiers are connected directly to the drive units, for more accurate handling of the crossover points and improvement in control is given by direct connection between the power amplifier and drive unit.

Uncompromised Performance

ATC’s distinct tampering procedure offers an outstanding balance of high damping and low mass, ideal for subduing adverse energy from diaphragm resonances. Configured with a short edge-wound voice coil in a long, narrow magnetic gap, the speakers ensure there is exceptionally low distortion throughout the operating band and eliminates the need for ferrofluids that can dry out over time leading to a compromise in performance.

Sleek cabinet

The curved cabinet construction is not only visually stunning, it is also acoustically braced and laminated for high rigor and damping to convey a strong impression of design quality. The metal grille uses hidden magnets to attach to the cabinet easily. Manufactured in-house, the ATC SCM40A is a hand-built ruggedly engineered speaker, world famous for musical accuracy and high power output.

About ATC

ATC was formed in 1974 by Billy Woodman to manufacture custom drive units for the professional sound industry, they quickly made their 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.

1976 saw the first production of the ground-breaking SM 75-150s soft dome midrange driver, a technical tour-de-force, whose innovative up-scaled design reproduced a more uniform dispersion, wider bandwidth and much lower distortion than was thought possible at the time. It revolutionised studio monitoring and has since become recognised as the ultimate mid-range transducer for both domestic and professional applications. Utilising exotic materials and precision tolerances, the latest version of the SM 75-150s represents the apex of drive unit technology. It is often copied but never equalled.
