Perhaps this will help, here's an example of a system using the 4540ND with the DDS ENG-1 waveguide

You need a measurement of the compression driver with the horn you are going to use to do the compensation. It would also my be helpful if you have an impedence and phase plot of the driver with the horn installed as well.

At the very least we would need to know what horn you want to use so if someone has done this before they can help you out.

i have no idea what horn to use. a good one i guess.

yeah i kinda figured that i should buy one and a horn then measure the response and impedance with them together.
