1.8" | 181FCD
Ferrite Compression Driver
Key features:
- EXTENDED FREQUENCY RESPONSE
- FEM optimized magnetic structure
- Use in larger speaker systems
Design notes:
The 181FCD compression driver is a very high performance high frequency device ideal for professional loudspeaker systems. The driver’s dome is carefully attached to based magnetic circuit provides a robust, high force BL field, providing precision control of the Polyimide diaphragm assembly. We have optimized the overall performance of this compression driver to deliver pleasant sound.
