Personally, I like using a good 1" exit driver with top-octave compensation to compensate for falling power response. That will get you to 18kHz. If you want to use a larger compression driver, you'll need to use a super-tweeter for the top octave. In that case, I'd probably go with something like the JBL 2405.
