Dynamic Sonic Engine

Our molded enclosure houses the super-accurate ring radiator tweeter and the extended motion midrange driver in separate tuned compartments. It provides wider, uniform dispersion in the critical 200Hz - 2kHz range and reduces performance-robbing back wave reflections.

Cassini Oval Subwoofer Drivers

We increased the surface area on the subwoofer driver cones give you deeper, more musical bass response and dramatically enhanced imaging. Blending is smooth—and with the voice coil design offers larger excursions and higher power handling.
