Driver recommendation needed - self-contained tweeters & mid-range
 
Hi guys. Please help to identify and recommend tweeters and mid-range drivers that are self contained is having some sort of steel casing in the back?

Are ring radiators self contained or they are more like bi-poled since the seems to have that nipple like thing facing the back?

Don't worry, all ring/dome/cone tweeters have closed back.
Regarding midranges, simply observe if they have closed back.

:thanks Sonce, I was somewhat fascinated by ring radiator but was puzzled by that bigger nipple in the back and feedback about rings narrow dispersion. In fact how does one find out about drivers' dispersion? I don't find them on specs.

Eminence manufactures a few sealed back midrange speakers. Study the SPL and Impedance curves carefully during your design.
