ATC C1 Sub Mk2 – Active 12" Subwoofer with Studio Precision

The ATC C1 Sub Mk2 is a compact, high-performance active subwoofer designed specifically to perfectly complement the ATC Entry and home cinema series. It delivers a deep, controlled, and extremely precise bass foundation while remaining true to the classic ATC philosophy: maximum neutrality, minimal distortion, and complete control over the musical signal.

Equipped with a hand-built 12" (314 mm) bass driver and a powerful integrated 200-watt Class AB MOSFET amplifier, the C1 Sub Mk2 achieves impressive low-frequency reproduction without losing precision or speed. The sealed, low-resonance cabinet ensures tight, fast bass – ideal for both music and home cinema alike.

Thanks to extensive adjustment options (low-pass, gain, phase, and polarity), the subwoofer can be optimally integrated into any system and harmonizes particularly well with models such as the SCM7, SCM11, SCM19, and SCM40, as well as the C1C and C3C center speakers.
