According to the NRC anechoic measurements the Persona’s 7 inch midrange starts beaming around 1500hz. The driver is crossed over at 2K. The Harman anechoic chamber also measured a sound power drop of about 5db in the 1.5-2k range in their measurements of the Persona.

A lot of companies won’t mate a 1" tweeter with a large woofer because of the directivity issues it causes.
