Back to Overview
The C90-6-726 is a 5 inch midrange driver with ceramic dome.
Using the same parts as BD90-6-727, the innovative construction provides ideal conditions for layouting the spider and magnetic system, which in combination with our proprietary ceramic cone ensures the lowest distortion rates that we have ever achieved for a ceramic cone midrange. The new design facilitates an ideal acoustical center identical to our CELL tweeters and bass drivers. The magnetic system which delivers 1.8 Tesla does not cover the rear of the dome, eliminating reflections and energy storage. Our proprietary CELL-clamping technology enables easy assembly and adjustment for various front panel designs. Your individual logo can be applied to the milled basket upon request.
We recommend our C90-6-726 for an application from 200 Hz – 6000 Hz.
