SCM25A Pro Mk2
Introducing the
SCM25A Pro Mk2
Compact Active 3-Way Studio Monitor
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.

SCM25ATH Pro Mk2
Top Hat Mount Studio Monitor
The SCM25ATH Pro Mk2 is a wall bracket mount variant of the SCM25A Pro Mk2. Its performance matches that of the nearfield version but its cabinet features a ‘top-hat’ in its base for mating with the Konig & Meyer 24120 bracket*
The SCM25Ai Pro Mk2 is well suited to surround channel use in multi-channel surround and immersive audio applications, such as Dolby Atmos.
