About the SCM20ASL Pro

The ATC SCM20ASL Pro is a compact, very high-performance 2-way active studio monitor designed for critical near-field listening, LCR surround monitoring in small-to-medium control rooms, and surround channels in larger rooms. It features ATC's proprietary 150mm/6" Super Linear mid/bass driver with a large 75mm/3" voice coil and a 25mm/1" dual suspension soft dome tweeter. The speaker uses discrete MOSFET class A/B bi-amplification with 200W for bass and 50W for high frequencies, ensuring precise power delivery tailored to each driver. The sealed cabinet design provides well-controlled bass response, optimized for small to medium listening environments. The crossover frequency is 2.1kHz with 2nd order critically damped filters, and the speaker includes input sensitivity and bass trim controls for room and source optimization. It has a balanced XLR input and features overload protection and front panel indicators for power and gain reduction. Dimensions are 450 x 250 x 392 mm and weight is 23.4 kg per cabinet.
