Renkus-Heinz CDT500

Complex Conic Horns with CoEntrant Driver


CDT Series horn/driver assemblies combine two significant breakthroughs in acoustical design. Complex Conic horns maintain constant directivity over a wider beamwidth, and our patented CoEntrant transducer is the first new approach to converting electrical energy into acoustical power since the compression driver.



CoEntrant Topology (U.S. Pat. 5,526,456)

Integrates a midrange cone and HF compression driver into a true point source with inherent time-alignment.


Complex Conic: The Next Step in Horn Evolution

Complex Conic horns provide superior pattern control and more natural sound; may be rotated 90º.


High-Frequency Compression Driver

Provides crystal clear highs from 1800 Hz to18 kHz.


Eight-Inch Mid-Range Cone Transducer

Easily extends response down to 350 Hz with low distortion.


Weather Resistant Design

Sealed driver enclosure and weather resistant cone offer maximum protection from the elements.


Choice of Coverage Patterns

Choose between 90º by 40º, 60º by 40º , 60º by 60º and long throw 40º by 40º designs



Choice of Models


The CDT500-64K is a medium throw horn with a 60º by 40º coverage pattern.

The CDT500-94K is a medium throw horn with a 90º by 40º coverage pattern.

The CDT500-44K features long throw 40º by 40º dispersion.

The CDT500-66K features 60º by 60º coverage, ideal for overhead distributed systems used in large high ceiling areas.


All four models provide tight pattern control down to 500 Hz and below. They come complete with a built-in crossover and a weather resistant housing for the driver/crossover network.
