The 180NCD compression driver is a high performance high frequency device ideal for professional loudspeaker systems. In a ultra compact size, the driver’s neodymium based magnetic circuit provides a robust, high force BL field providing precision control of the Polyimide diaphragm assembly. The unit delivers extended frequency response and high power handling through 1.0 inch exit throat. The suspension has designed and FEM optimized venting features to lover the harmonic distortion. The venting holes also improves the control over the dome movements at low frequencies. REDCATT has developed unique phase plug. Phase plug is FEM optimized to lower the distortion artifacts at mid frequencies. 180NCD ultra compact design ensures the driver can be used in enclosure designs where the space is very limited, such as line array systems. Magnetic Circuit DesignRedcatt has focused on designing an optimized neodymium based magnetic circuit capable of delivering the highest level of performance and value. This effort has resulted in a device that offers uncompromising performance featuring high efficiency, exceptional transient response and controlled distortion characteristics, all
