Introducing the ATC SCM11

High-Performance Bookshelf Speaker Pair from ATC
The ATC SCM11 is a flagship bookshelf speaker from ATC Loudspeaker Technology, designed to deliver reference-quality sound in home and studio environments. Built in the UK with ATC’s legendary engineering, the SCM11 combines precise midrange reproduction with powerful, controlled bass and transparent highs.
The SCM11 features a three-way design, including ATC’s in-house 200 mm mid/bass drivers and a high-performance soft dome tweeter. This configuration provides exceptional detail, dynamic range, and a natural, uncoloured tonal balance that allows every nuance of the music to shine. Imaging and soundstage are incredibly precise, making the SCM11 ideal for serious music enthusiasts and audiophiles.
Designed for larger rooms, the SCM11’s sealed cabinet ensures tight, accurate bass and consistent performance regardless of placement. Paired with a quality amplifier, these speakers reveal the depth and emotion of recordings, whether listening to vinyl, digital files, or high-resolution audio.
About ATC
Founded in 1974 in the UK by Billy Woodman, ATC (Acoustic Transducer Company) is renowned for building some of the most accurate and dynamic loudspeakers in the world. Unlike many brands, ATC designs and manufactures its drive units entirely in-house, ensuring complete control over performance and consistency.
At the heart of many models is the legendary Soft Dome midrange driver, famous for its natural vocal reproduction and exceptionally low distortion. This clarity through the critical midband is why ATC loudspeakers are trusted in professional recording and mastering studios worldwide.
Available in both passive and fully active designs, ATC speakers prioritise neutrality, control and wide dynamic range. They are not voiced to flatter recordings — they are engineered to reveal them.
Built in England and backed by a six-year warranty, ATC loudspeakers are designed to deliver decades of musical accuracy and enjoyment.
