Horn Configuration

The configuration of the directivity is made by inserting two 
half horns, separated by a divider, into a frame holder. The 
Compression driver is fixed to this frame so there is no need to 
touch it when rotating or changing the configuration. By selecting 
different half horn you will be able to achieve different directives.

In the example, two 45° half horns make a 90° directivity. The 
directivity of the other plane is always 50°.
