@Kwesi congrats on the build. It looks great.
Is a period in arta 1ms?

If you ever want to clean the HF, i put this around the box for my t25:

The time will change with frequency. It is very difficult to compare a CSD against a Burst Decay Plot

Thanks, fluid. That makes it clear.
@Kwesi can you post a wav export from Arta of the mid? 0 and 30-ish deg if you have them. I can tinker with that in REW.
I may do so, but I've only saved these measurements which also include heavy influence from the baffle and maybe the enclosure:
Note that every linear distortion (= irregularities in the frequency response) will have direct influence to the decay behaviour connected to evaluation procedure. You can hardly separate that - if you want to analyze nonlinear behaviour, e.g. resonances with energy storing effect caused by the driver physics, you will need infinite baffle responses free of other disturbing effects. I fear a bit misinterpretation of the pure driver behaviour, as edge reflections and maybe even resonances / standing waves within the enclosure are included in my measurements.
Best regards

Cheers. That is fine and to be expected. I am more interested in the GD on and off-axis and the decay. This won't be for modeling anything.
