Additional Note:

The partnership with Materion is just starting. Production is being setup in our factory in Pomona, CA, where all machinery is now in place. Training will need to be completed for additional processes.  Radian is manufacturing Truextent® premium acoustic beryllium diaphragms under contract to Materion, using Materion’s genuine beryllium acoustic domes manufactured by Materion at their plant in Elmore, Ohio. For products listed in Radian's catalog, Radian is able to complete the assembly and ship products now. New product items previously sold by Materion will be assembled by Radian in the future - engineering is now working on those. New developments will be carried out already by Radian, assisted by Materion. The process will need to be gradual and priorities on manufacturing are still being established as ramping up production is planned.

All enquiries will be addressed.

Radian will be announcing Beryllium Truextent products as they become available.

We truly appreciate everyone's interest and the many encouraging messages we received.
