Some time ago I developed a miniature speaker for my nephew. He asked me if I could do something with the TB W3-1723 as he wants a small coaxial system.
The result was a very small and fine speaker with the W3-1723:
I developed 2 different X-over versions. One for higher SPL and one for better directivity control.
You can download Project1 here and Project2 here.
Maybe some of you were looking for such a speaker.

Nico
