Hi Forum Friends

Radian started production of the 475PB with Truextent Beryllium Diaphragm.
It's an excellent 1 inch driver with 1,75 inch diaphragm.

I just received 4 units and they measure promising. No curves to share yet. Well behaviour up to 30kHz

For prices contact your Radian dealer. Well below TAD but still nothing for bargainers.

THESE DIAPHRAGMS DO NOT FIT JBL DRIVERS!
