Aurum Cantus AC165/50CK 6-1/2" Midwoofer

The Aurum Cantus AC165/50CK 6-1/2" midwoofer employs a large diameter voice coil, a non-woven carbon fiber/Kevlar composite cone, and a high-strength ceramic ferite magnet. The tailored response of the speaker's exotic yet supremely engineered cone selection 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.

Aurum Cantus AC165/50CK 6-1/2" Midwoofer

I have enclosures(Capriccio 6 from Zalytron) and wanted to know what drivers and tweeters you would recommend for them. Built for Focal drivers/tweeters but wondered if there are better options for the same price. Thanks
