The ATC C6C is a high-performance active centre channel loudspeaker designed for reference-level home cinema and multi-channel systems. It delivers exceptional clarity, dynamics, and tonal accuracy for demanding surround sound applications.
In addition, the C6C is designed to match ATC systems such as the SCM50, SCM100, and SCM150. Therefore, it ensures seamless tonal integration across the front stage in high-end surround setups.
High-performance active centre channel design
The C6C uses twin ATC 234mm SL bass drivers together with the ATC SM-150S soft dome midrange driver. In addition, each driver uses massive shielded motor assemblies and in-house hand-wound precision flat wire coils. As a result, it delivers very low distortion, strong control, and highly accurate midrange performance.
Built-in amplification and active control
The C6C includes a 350W Class A/B ATC amplifier pack. Furthermore, active filters and overload protection ensure stable operation and clean performance. Therefore, the speaker maintains control and clarity even at high output levels.
System matching and surround integration
The C6C is designed to integrate with ATC SCM50, SCM100, and SCM150 systems. As a result, it delivers a smooth and consistent tonal match across the entire front soundstage. In addition, it improves dialogue clarity and imaging precision in cinema setups.
Build and reliability
The C6C is hand built in the UK and designed for long-term reliability. In addition, it is supported by ATC’s 6-year warranty.
