Wilson Benesch has their own house drivers, though I think they use a ScanSpeak tweeter.

And doesn't Sonus Faber also have their own drivers?
Decware does for sure.


To clarify regarding Wilson Benesch, their top Geometry series speakers use entirely custom drivers including a unique in-house designed tweeter.
Paradigm.  Totally vertically integrated...they design and manufacture their drivers, cabinets, etc.
As a point of clarification many of the companies listed use their own driver designs, but not all actually manufacture the drivers themselves. Many companies use existing driver manufacturers to build custom drivers to their specs.
