The above article explains how piezoe elements are made...such that 1 of the frequencies vibrates along the "thickness" of the piezo ....and the other frequency vibrates along the "diameter" of the piezo...

The 2d piezo in the HDSI xducer is made to vibrate at 200kHz/83kHz...
The 2d piezo in the XNT 9 DI T xducer is made to vibrate at 455kHz/200kHz...

It is possible that the 200kHz of the HDSI is vibrating across the "thickness" of the piezo...and the 200kHz of the XNT 9 DI T is vibrating across the "diameter" of the piezo...(or vice-versa)
