The ATC SCM150A SLT is a reference-level active floorstanding loudspeaker designed for exceptional accuracy, dynamics, and natural sound. It combines ATC’s proven driver technology with built-in tri-amplification. As a result, it delivers outstanding detail, powerful bass, and effortless musical realism.
In addition, the SCM150A SLT offers wide and even dispersion. This creates a spacious soundstage with precise instrument placement and excellent stereo imaging, making it equally impressive with both music and movies.
Advanced active three-way system
The SCM150A SLT features the ATC SM75-150S soft dome midrange driver together with the latest 375mm SL specification bass driver. Furthermore, the large ATC motor assembly improves control and reduces distortion. Because of this, the speaker delivers deep bass, natural vocals, and exceptional accuracy.
Built-in tri-amplification
A dedicated 350W Class A/B tri-amplifier powers each drive unit individually. At the same time, active crossover filters and overload protection keep every driver working at its best, ensuring excellent integration and low distortion.
