The ATC C3C is a high-performance centre channel loudspeaker designed for accurate dialogue reproduction and seamless integration in home cinema systems. It delivers clear, natural sound with strong focus and excellent detail, making it ideal for multi-channel setups.
In addition, the C3C is designed to match ATC systems such as the SCM11, SCM19, and SCM40. Therefore, it ensures consistent tonal balance and smooth integration across the front soundstage in surround systems.
High-performance driver design
The C3C uses a newly designed 25mm soft dome tweeter with a precision alloy wave guide. In addition, it features twin 150mm CLD mid/bass drivers. As a result, it delivers clear highs, natural midrange, and controlled bass response.
CLD mid/bass technology
The twin CLD (Constrained Layer Damping) mid/bass drivers reduce distortion and improve clarity. Therefore, dialogue remains precise and natural, even during demanding film soundtracks.
Advanced motor and coil design
The C3C uses massive FEA-optimised motor assemblies combined with precision undercut bass poles. In addition, in-house hand-wound flat wire coils improve efficiency and control. As a result, the speaker delivers accurate dynamics and low distortion.
Amplifier-friendly design
The C3C features a flat impedance curve. Therefore, it presents an easy and stable load for a wide range of amplifiers and works well in many system configurations.
System matching
The C3C is designed to integrate with ATC SCM11, SCM19, and SCM40 loudspeakers. In addition, it ensures a consistent tonal balance across the entire front channel array for home cinema use.
Build and reliability
The C3C is hand built in the UK and designed for long-term performance. In addition, it is supported by ATC’s 6-year warranty.
