CL-42 4” mid-woofer is so efficient, it can play much higher into the midrange frequencies above 11kHz.The cone of the CL-4 mid is made of a light yet rigid, mixed fabric carbon coated paper. The type cone material among audiophile listeners considered the best for sound quality

Engineering a perfect compliment to the highly acclaimed CDT drivers was an equally challenging task. "The Elliptic" crossovers, called SatNet, are an engineering breakthrough for car audio.

They use an ingeniously designed fifth order, elliptic type network that creates very distinct advantages over conventional "Butterworth" or "Linkwitz-Riley" passive filter topologies. This topology is so unique that this is the VERY FIRST TIME it has been used commercially in a car audio application.

EX-484 is a new 2010 design that provides the essential CDT Audio Elliptic xover topology in the most affordable package. The two-way crossover is composed of a 5th order elliptic high pass network for the Tweeter and first order butterworth for the woofer. Three Tweeter levels are selectable. Tweeter protection is provided. Crossover takes place at 4.3kHz. Mylar and film capacitors in the Tweeter network. This provides greater power handling and clarity..

CDTAUDIO 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 higher reliability. Our incredible midbass 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. Our special "Contoured Dispersion" radiation pattern in the critical midrange frequencies delivers rock solid imaging and front staging, with virtually no "side biasing."
The carbon treated paper cones offer ideal stiffness and damping. The curvilinear cone shape prevents cone flex and break up. This provides clean midbass even at higher levels. The always-critical midrange frequencies are clear and precise with no distortion from "ringing." The midbass/midrange drivers 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.
