Aurum Cantus AC300/75C2C 12" Woofer

The Aurum Cantus AC300/75C2C 12" woofer features a 3" diameter voice coil, which combined with extensive thermal management techniques provides outstanding power handling and realistic impact. The tailored response of the speaker's exotic yet supremely engineered non-woven carbon fiber sandwich cone delivers the signature Aurum Cantus combination of depth, accuracy, and listenability.

Aurum Cantus woofers are characterized by fast transient response, minimal tonal coloration, and deep, dynamic bass.
