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. A copper-plated flat aluminum wire voice coil provides high efficiency and excellent power handling, complemented by a low-distortion magnet system and precisely cast aluminum alloy basket. Aurum Cantus woofers are characterized by fast transient response, minimal tonal coloration, and deep, dynamic bass.
