Dome Diaphragms

Commonly dome diaphragms consist of a very fine fabric and integrate a fabric dome and a surround. The surround of a dome diaphragm is not pasted afterwards, but formed simultaneously with the hard dome production with a convex or concave shape.

For dome diaphragms DKM uses fabrics with grammages of 60 g/sq.m, which are coated according to the application. The optimal balance of fabric and resin leads to the required mechanical strength.

Dome diaphragms typically are used for tweeters in sizes from 1 to 3 inches.

For tweeters DKM furthermore provides pre-assembled modules of hard dome and soft surround as assembled dome diaphragms as well as conventional tweeter cones.
