Description
This 1” compact Illuminator beryllium tweeter is an example of a big sound in a small body. As beryllium is a material characterised by great stiffness, light weight and high damping, the beryllium diaphragm offers all the properties required to reproduce excellent sound. And indeed, the 1” tweeter sounds great. It has a very low distortion and a distinct clarity that brings out the best in all types of music.
Features
- 1" Beryllium diaphragm (99% pure BE)
- Large non resonant aluminium enclosure
- Sound transparent protective grill
- Patented symetrical drive (SD-2) motor
- Large roll surround f. wide dispersion
- Applicable for HiFi and automotive
