Product Description

ATC’s C1 active subwoofer is a compact, substantially braced design with a hand-built 12” ATC bass driver and a fully discrete 200W MOSFET power amplifier.

Multichannel System

The C1 subwoofer forms part of the ATC Concept 1 multichannel speaker system offering a cleverly balanced and naturally sounding subwoofer. The ATC C1 provides subwoofer both the weight and finest scale of any reproduction available.

Magentic Hysteresis

Manufactured in house to exacting tolerances; ATC's drivers are legendary for their many design innovations. It has long been recognized that the detrimental effects of magnetic hysteresis is a significant factor in the production of distortion in loudspeaker drive units.

With the clever use of revolutionary materials developed for the communications industry, the problem has been solved with ATC's SL drive units. They are unique not only in their ability to accurately reproduce piano, but also the precise manner in which they articulate male voices.

Build & Finish

The ATC C1 subwoofer, featuring a traditionally-styled enclosure and real wood veneer, can be easily integrated into any interior. The ATC C1's compact design lends itself perfectly to smaller installations up to approximately 25 square metres


Designed to match ATC's entry level speakers to be used in a multichannel set-up, the ATC C1 is a good match with ATC SCM7, SCM11, SCM19, SCM40 and with C1C centre speaker. For an immersive home cinema set up, click here to view the ATC C1 5.1 package.
