Core Features
-
Extremely Realistic Human Voice Dialogue: Thanks to ATC's legendary mid-range tuning technology, the C1C boasts extremely high sound density.

-
Perfect Multi-channel Matching: The C1C's acoustic design specifically emphasizes tonal consistency with other series from the same brand (such as the classic SCM / HTS 7 or SCM / HTS 11). When combined to form a multi-channel system, they exhibit seamless soundstage coherence and dynamic envelopment.
For enthusiasts who want to enjoy authentic British monitoring style in their living room and refuse to compromise on the clarity of movie dialogue, the hand-built ATC C1C is the top choice for building a high-quality home theater!
