    Midbass drivers, featuring our compound curvature, carbon treated cones for "Contoured Dispersion." Stainless steel top and bottom plate for heat dissipation. Gold plated terminals. Real butyl rubber surrounds and flat spiders for linear cone excursion.

    CDT designs and builds its drivers and crossovers to the very highest of standards. Years of experience and design flexibility yield higher quality and better performance. Quite simply, we produce "audiophile" sound, smoother response, wider dynamic range, and better imaging and sound staging. Our incredible midbass and midrange drivers are flat to 6 kHz! That's 6 octaves response! This puts much less stress on the tweeter, providing better power handling and much better sound. Our special "Contoured Dispersion" radiation pattern in the critical midrange frequencies delivers rock solid imaging and front staging, with virtually no side biasing. These carbon treated cones are smooth and natural sounding thanks to an ideal combination of stiffness and damping. The compound curvature shape prevents cone flex and break-up. This provides clean midbass, even at higher levels. The critical midrange frequencies are clear and precise with no distortion from "ringing." The mids use a real butyl rubber surround, not merely a mixed butyl compound.
