The point source for your musical application, designed and manufactured without compromises:

 

Tweeters don't like prefixed, swinging horns and answer this with a nonlinear frequency response and a early decrease to the high frequencies - notably under listening angle. 

They don't even like to be placed at the side of their big brother, showing various nonlinear frequency resonses under variuos listening angles.

The consequent solution to all this problems is the  inverted woofer cone. Hard to handle in construction and manufacturing of the driver itself, but therefore just easy to handle in loudspeaker construction.

This unit, constructed and manufactured perfectly to this mission, will be the heart of your next loudspeaker.
