Available in either black or white satin finish, or alternatively cherry or black ash wood veneer, the ATC SCM40 are hand-built speakers made using a unique curved cabinet design. This subtle touch adds a classic elegance to any listening space.

Pleasingly solid and substantial at 40 litres volume capacity, the ATC SCM40 features a braced and laminated cabinet design which adds strength and damping to the overall quality finish.

A new soft-dome tweeter is used (the SH25-76) which employs a unique dual-suspension system to suppress diaphragm rocking modes, even at high output levels. Also included are ATC’s own 75 mm soft dome midrange driver and a 164mm short bass driver, all of which are made without the use of ferrofluids for continuous performance which does not degrade over time.

Detailed and spacious, with a superb low-end presentation, these 3-way passive loudspeakers are easy to drive, premium-looking, and superb sounding. Please get in touch to arrange a demonstration.
