ATC SCM25A PRO MKII – compact 3-way active studio monitors with 6.5" woofer, Class A/B amplification and exceptional midrange clarity.
The ATC SCM25A PRO MKII is a high-performance 3-way nearfield monitor designed for critical studio environments. Built around a 6.5-inch bass driver in a 25-litre vented cabinet, it offers a balanced combination of powerful low-end extension, detailed midrange, and accurate highs. The MkII version introduces ATC’s upgraded SH25-76S dual-suspension tweeter, delivering extended HF response with reduced distortion. With a total Class A/B power output of 242W, separate amplifiers drive each driver individually, ensuring superb control and dynamic accuracy. An ideal choice for mixing, mastering, and immersive setups where transparency and imaging are critical.
