About the product


The SCM19AT (Active Tower) takes the drivers from the well-reviewed SCM19 and packages them in a floorstanding configuration with active crossover and bi-amplification. The cabinet features curved sides and a sealed box bass alignment.

Drive units are made in house:

  • 1" ATC soft dome featuring a 1.5 tesla neodymium magnet with dual suspension and no ferrofluid for long life.
  • 6" ATC Super Linear mid / woofer featuring a short coil / long gap voicecoil, a huge 19.8lb magnet system and integral 3" soft dome for wide mid-frequency dispersion.

Since this is an active speaker, each driver gets its own amplifier. The tweeter is powered by a 32W amp and the mid / woofer gets a 150W. The crossover incorporates phase compensation and higher order slopes than the passive version, and the input is via XLR.


    • Positive Feedback Online: "The SCM19ATs are a wonderful advancement in the state of the art of active loudspeakers. You could easily spend three times as much on comparable separate components and not do as well. I strongly encourage you to seek out the ATCs and give them a listen."
    • Hi-Fi Choice Editor's Choice: "Even if you’re familiar with the dynamic largess and gloriously un-hyped presentation of the standmount passive SCM19, this active tower moves the game on in unmistakable ways. In raw terms it goes louder with less distortion while exhibiting tighter control, wider and more finely graded dynamic contrasts, a deeper, harder-hitting bass and greater rhythmic impetus and drive."
