The SCM25A Pro Mk2 is a compact 3-way high-performance active studio monitor loudspeaker, based around a 6.5”/164mm bass driver. The monitors combination of exceptional mid-range clarity, high output, extended bass response and modest size makes it ideal for nearfield monitoring in a wide range of critical applications.
The latest Mk2 version is updated with ATC’s latest SH25-76S ‘Dual Suspension’ tweeter, extending the high-frequency response along with a reduction in distortion. These improvements ensure faster decision making and outstanding translation outside the studio.
