CDT Audio 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, they produce "audiophile" sound, smoother response, wider dynamic range, and better imaging and higher reliability. Our incredible mid-bass and midrange drivers are flat to 7khz! That's 6.5-octave response!
This puts much less stress on the Tweeter, providing greater power handling and much better sound. Their special "Contoured Dispersion" radiation pattern in the critical midrange frequencies delivers rock solid imaging and front staging, with virtually no "side biasing".

The carbon coated compound mix-fabric paper cones offer ideal stiffness and damping. The curvilinear cone shape prevents cone flex and break up. This provides clean mid-bass even at higher levels. The always-critical midrange frequencies are clear and precise with no distortion from "ringing." The midrange driver use real butyl surrounds, not merely a mixed butyl compound. This provides longer, more linear excursion, and a far longer life because it's UV resistant.
