ATC C1 MK2 Subwoofer

The ATC C1 MK2 is a high-performance active subwoofer designed to provide the deep, cinematic bass extension that audiophiles demand without sacrificing the rhythmic precision ATC is world-famous for. Hand-built in the UK, the MK2 features a massive, proprietary 12-inch (300mm) driver driven by a refined 200W Class A/B MOSFET amplifier.

What sets the C1 MK2 apart is its studio-derived heritage; it is engineered to be 'critically damped,' meaning it avoids the muddy, lingering bass notes common in lesser subwoofers. With its rigid cabinet construction and advanced low-pass filter controls, it integrates invisibly into both stereo and multi-channel systems. Whether you are filling in the bottom octave of a pair of SCM7 monitors or anchoring a full home theatre, the C1 MK2 delivers a foundation of power, texture, and absolute control.
