You have measurements yet? REW is good, it even does electrical including TSP's now.

Hi NEO Dan,
I will go look for that ,I am not a speaker tester new ground so to speaker ,One speaker is built and working,lol. I did run a Z and a free air in DATS,I did download ARTA and have been digesting it's contents,I'll find REW and check back,It is playing and sounding good still a little cone stiff but getting better sounding each time I play it.
I f you would like to tutor me along, I need the help ,mostly understanding the results I get ,the graphs and plots I am not familiar with!
PM if you like!
Thanks,
NS

REW
It's hosted at another forum, and membership(free) is required to download. I don't hang out there like I used to but I still really like REW.
Sure I'll help you get REW running.
What's the DATS sweep looking like, can you post it???

Those of us without the DATS can't open the file, unfortunately.
Can you make a high resloution export or screen shot of the impedance and phase?

Interesting that the in box sweep is so rough. Once your impedance bridge is working REW or STEPS will give you much cleaner results. FB is ~35Hz as expected.

Well when ever you get it working there is a way to export the data into a usable .zma file:
