About the SCM20A
The ATC SCM20A is a compact professional 2-way active monitor using ATC's 150mm (6") Super Linear mid/bass driver and a 25mm (1") soft-dome tweeter in a sealed, heavily braced enclosure for neutral, low-distortion monitoring. It incorporates an onboard Class AB MOSFET bi-amp pack delivering approximately 200W to the mid/bass driver and 50W to the tweeter, with active crossovers and protection circuitry derived from ATC's Amp Pack designs used in the SCM20ASL/Pro models. The rigid, closed-box cabinet construction prioritises accuracy over bass extension and is intended for nearfield or midfield monitoring in professional studios. A closely related floor-standing active tower variant using the same drive units and amplifier topology is offered as the SCM20ASLT.
