ATC SCM25A Pro MK2 - 3 Way Active Studio Monitor (Each)

About: ATC SCM25A Pro MK2 - 3 Way Active Studio Monitor (Each)

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.

Key Features

• 3-way design featuring ATC SM75-150 Soft Dome mid-range driver.
• Wide dispersion vs frequency for excellent stereo imaging over a large listening area.
• ATC discrete MOSFET class A/B amp-pack delivers high dynamic range in combination with very low distortion and an extended HF bandwidth.
• 4th order active crossovers with all-pass phase compensation ensure outstanding driver integration.
• Input sensitivity and bass ‘lift’ user controls.
• Hand-built in England and covered by a 6-year warranty.
