grannyring4 Hi. ET338 is a dynamic tweeter with a good transfer of coppers plates.
But not enough air sound. I want more air in the music.

You should try the Mundorf EVO SIO.

I find they exaggerate this effect, so I don't like them, but I think you would. :)

Best,

Erik is right about the Mundorf cap.  If you want more air with a more natural and real tone, then Jupiter copper foil is your best bet. They are not cheap however.
