COLLECTORS’ ITEM: The First Generation ATC SCM20

A definitive classic . . . . .

The SCM20 is  a definitive classic monitor and represented ATC's first venture into domestic monitoring.

Central to its performance is the mid/bass unit designed by Billy Woodman and hand made in house at ATC. The hybrid design incorporates a 150mm bass cone on to which is grafted a 75mm soft dome.

This original first generation version has been claimed by audiophiles to be of the “highest density” sound., with the original professional design with NO bi-wire setting. The speaker terminal is the original British made “Mitchel” Gold Plated classic.

Not only does the SCM20 reproduce bass with remarkable articulation and authority, it also has outstanding mid-band clarity, incredible dynamic range, and awesome power handling.
