The Aurum Cantus AC250/75C2C 10" large diameter voice coil woofer performs superbly, aided by its carefully engineered non-woven carbon fiber sandwich cone. A copper-plated flat aluminum wire 3" 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.
