Key Benefits
Lightweight Design
15-30% lighter than pure copper, reducing moving mass for improved transient response.
High-Frequency Performance
Skin effect at audio frequencies concentrates current in copper cladding for efficient HF response.
Cost Effective
Lower material cost than pure copper while maintaining audio quality.
Applications
Headphone Drivers
Lightweight CCAW for in-ear and over-ear headphone voice coils.
Tweeters
Fine CCAW for high-frequency tweeter coils with excellent HF extension.
Professional Audio
Premium CCAW for studio monitors and professional speaker systems.
Frequently Asked Questions
Does CCAW affect audio quality?
At audio frequencies, skin effect concentrates current in the copper cladding, so CCAW performs similarly to pure copper for voice coil applications. The reduced moving mass can actually improve transient response.
