ATC launches C1 Sub Mk 2 active subwoofer

ATC has revealed the new C1 Sub Mk 2 subwoofer to provide a dynamic low-distortion bass foundation to pair with some of its loudspeaker lines.

The new active subwoofer is a compact real wood veneered design, incorporating a hand-built 12-in ATC bass driver and a fully discrete ATC 200W MOSFET power amplifier. 

Designed for both music and cinema applications, the C1 subwoofer replaces the Mk1 version and delivers a quality of low-frequency reproduction for ATC’s Entry Series speakers, the C1C and C3C centre speakers, HTS Series on-wall speakers, and all but the largest satellite speaker systems. 

Its re-engineered design incorporates ATC’s transparent circuits boosted by larger power supplies, the latest ATC grounded-source 200W Class A/B discrete MOSFET power module and improved overload protection circuitry (with front-panel indicator) for greater control at full output.

The low-pass filter circuits have been re-worked to enable the best possible integration with partnering speakers from ATC and other manufacturers.

The hand-built 12-in bass driver uses a massive motor assembly and three-in ribbon voice-coil, and delivers clean and dynamic low frequencies down to 25Hz. 

It is recommended that a single C1 sub is partnered with speakers up to the SCM19 and HTS11, and that two subs partner with the SCM40 and HTS40, although this is not essential in all room sizes.

Available this month, the C1 sub has four real wood finish options: Cherry, Black Ash, Satin Black, or Satin White.
