ATC SCM100A SL Classic

The ATC SCM100A SL Classic is a high-performance active loudspeaker designed for listeners and professionals who want exceptional accuracy, power, and control. In addition, it performs at the highest level in recording studios and premium home audio systems where precision and consistency matter.

As the active version of the SCM100 platform, the SCM100A SL Classic combines advanced driver technology with dedicated internal amplification and an active crossover design. As a result, it delivers highly accurate music and speech reproduction with impressive dynamics and excellent tonal balance.

ATC soft dome midrange driver

At the centre of the SCM100A SL Classic sits ATC’s renowned SM75-150S soft dome midrange driver. Therefore, vocals and instruments sound detailed, natural, and highly realistic. In addition, the dedicated midrange driver helps reduce colouration, which keeps recordings clear and transparent.

Upgraded tweeter and refined bass response

ATC improved the SCM100A SL Classic with an upgraded tweeter and an enhanced bass reflex port profile. As a result, high frequencies sound smoother and more detailed, while bass performance feels deeper and more controlled. At the same time, the speaker maintains excellent balance across the full frequency range.

12-inch bass driver with Super Linear technology

The SCM100A SL Classic features a professional-grade 12-inch bass driver with ATC’s proprietary Super Linear magnet system. Because of this design, the woofer delivers powerful low frequencies with lower distortion and greater control. In addition, the speaker maintains clean bass performance even at higher listening levels.

Dedicated MOS-FET amplification

The active design gives each driver its own dedicated and carefully matched MOS-FET amplifier. Therefore, the bass, midrange, and tweeter all receive power tailored to their needs. As a result, the system achieves better control, improved timing, and greater overall accuracy compared to traditional passive systems.

Precision active crossover design

ATC designed the active electronic crossover with wide bandwidth and extremely low distortion. In addition, the balanced input stage improves signal handling while maintaining excellent performance. As a result, the SCM100A SL Classic delivers smooth driver integration and a stable, highly detailed soundstage.

Wide dispersion and accurate imaging

The SCM100A SL Classic spreads sound evenly across the room, helping listeners enjoy accurate imaging from different seating positions. Therefore, it performs equally well in studio environments and larger home listening spaces. At the same time, it preserves tonal balance and clarity across the listening area.
