I'm planning to put these units into the boxex of Galante Audio Buckingham (originally installed with a PAS clone of Altec 604 series horn loaded coaxial driver). My intention is to avoid using any passive crossover other than a cap with a tweeter.

I wonder if I can use what is essentially a supertweeter from say 13kHz upwards. The stated response range of 420A is up to 14kHz. Please share your thoughts and experience. Thanks so much!!
