Engineered for the Purest Listening Experience
Every component of the ATC SCM20PSL Loudspeaker is built with precision and purpose. Both the mid-bass driver and soft dome tweeter are handmade by ATC in their UK facility, ensuring unmatched consistency and quality. The 150mm mid-bass unit features ATC’s proprietary ‘SL’ motor design, with a massive 75mm voice coil and long-gap, short-coil assembly, delivering fast, clean, and controlled bass with impressive dynamics.
The 25mm soft dome tweeter uses a high-energy 2.1 Tesla motor and dual suspension system for smooth, extended high frequencies without fatigue. These drivers are seamlessly integrated by a high-spec second-order crossover, featuring oversized air-core inductors (wound in-house) and high-voltage polypropylene capacitors for low loss and maximum reliability.
Housed in a sealed, heavy-duty cabinet with bitumastic damping panels, the SCM20PSL is designed to suppress cabinet colouration and preserve sonic purity. It performs exceptionally well in smaller rooms and close-to-wall setups, making it a go-to choice for music lovers who want reference-grade performance without floorstanding speakers.
At Soundstage Hi-Fi, we’ve tested the SCM20PSL extensively in our demo room, and it never fails to impress. Its clarity, timing, and balance make it one of the most revealing passive monitors in its class. Whether you’re matching with ATC’s own electronics or another high-quality system, we’re here to help you find the right pairing.
