jerome,
a dipole cares 90 % about dipole length and 10 % about shape. And don't forget that your 'shape' is in the dipole null mainly.

Dipole directivity and horn directivity are two very different concepts. They don't mix well.

I have written a follow-up to my post #54 in my thoughts about directivity.

Yes I have already read your thoughts
I don't have any opinions on this subject, it seems difficult to make a real dipole tweeter.
The NEO3 looks a very good candidate.

Appearing today, a cheap poly from PE, and a nice Tang-Band. This is the money shot:

The first picture is with the 4" poly in back to back, small sealed enclosures, getting measured.

Hi cuibono

This topic was helpful in my quest to get the ultimate dipole mid-high driver. The driver I'm currently using is the Omnes Audio bb3.01 This 3" is at the front near perfect cd till 5kHz +. At the back the power response drops steadily above 2kHz. Some measurement results can be found here: Toon onderwerp - CD Dipool project [prototype fase] • forum.zelfbouwaudio.nl

Are you still working with those TB's? Did you investigate some more since then?
