ATC Accuracy, Install-ready
The ATC SCM12i Pro is an installation-ready compact, high-performance 2-way passive studio monitor with cabinet mounting points for wall and ceiling mounting. The SCM12i Pro employs the company's proprietary Constrained Layer Damping (CLD) bass/midrange driver. CLD woofers use a multi-layered composite cone with a central damping layer that greatly reduces the audible artifacts of cone breakup. These drive units deliver outstanding clarity, even at high output levels. To ensure consistent performance over extended periods, the SH25-76 tweeter used in the SCM12i Pro is a unique dual-suspension unit that ensures free pistonic voice coil movement without reliance on ferrofluid. The ATC SCM12i Pro is ideal for critical nearfield monitoring applications in all control rooms and for surround applications in small-to-medium-sized rooms.

Proprietary drivers offer life-like playback
Great-sounding monitors start with great-sounding drivers. The SCM12i Pro's drivers are manufactured to exacting standards at ATC's in-house facility. Hand-wound voice coils are made from flat oxygen-free copper wire and operate in a precision long magnetic gap. Specially designed magnet vents not only reduce airflow noise and heat, but increase power handling and reliability. These drivers are designed to give you a smooth and even frequency response without built-in EQ. In short, the SCM12i Pro was designed to perform to exacting professional standards.


ATC's legacy of world-class audio
ATC has focused on one thing — creating the best speakers possible — since 1974. In the SCM12i Pro, you'll find that every component was designed for maximum accuracy and sonic clarity. For example, ATC's electronic crossover has built-in phase correction, solving a problem that causes smeared audio or a lack of definition. And ATC's famous Super Linear Drivers reduce harmonic distortion by 10–15dB compared to similar speakers, which means you'll hear every nuance of your audio exactly as it was recorded and mixed. If you want to make great-sounding recordings that "translate" to the world outside your studio, accurate monitors are a must. Sweetwater's advice: you can't go wrong with the studio monitors trusted by George Massenburg, Chuck Ainlay, Nathaniel Kunkel, and many other world-renowned engineers: ATC.
