Hello,

This is a sweep of my JBl 2452H compression driver attached to a JMLC 350hz horn with a 3D printed throat connector to match the driver exit and horn entrance angle.

Measurement was done at 5cm from the mouth.

Questions:
1) I take it the phase moving all over the place is a result of the diaphragm breakup from 7khz upwards?
2) I wish to use RePhase. Any tips?
3) How do I take gated measurements?
4) As I am using IIR filters, am I correct in saying that the difference from FIR to IIR is that IIR is not linear phase?

Any comments or opinions welcome!
