ATC - SCM20ASL - Classic Series 6" 2-Way Active Speakers (Pair)

The active SCM20ASL represents ATC’s premier 2-way stand-mount loudspeaker, tailored for listeners who demand uncompromising performance in moderately sized spaces. By integrating ATC’s 250 W “Amp Pack” directly into the cabinet, it removes the need for a separate power amplifier and passive crossover, offering a more cohesive and efficient system.

The heart of the SCM20ASL is its on-board module: a balanced input feeds a second-order Linkwitz-Riley electronic crossover, which in turn drives two class A/B MOSFET amplifiers—200 W for the 6″ Super Linear mid/bass driver and 50 W for the 1″ S-Spec soft-dome tweeter. This active topology yields tighter level and timing control, elevating dynamic range and transient response compared to passive designs. Inside, the cabinet’s robust bracing and bitumastic damping panels suppress resonance, ensuring coloration-free reproduction across a 55 Hz–25 kHz bandwidth. User-adjustable input sensitivity and bass-shelf controls allow precise room integration, while balanced XLR connectivity guarantees noise-immune operation.

With its fully integrated electronics, the SCM20ASL offers plug-and-play simplicity without sacrificing sonic nuance. Its precise active crossover and dedicated amplifiers ensure every drive unit operates at its peak, translating into effortless dynamics and lifelike imaging. Whether paired with a high-end preamplifier or a modern streaming preamp, this loudspeaker delivers ATC’s signature neutrality and musicality. For enthusiasts seeking a compact solution that outperforms convention, the SCM20ASL stands as a benchmark in active loudspeaker design.
