In inversing tweeter, spent some time listing it. It has at 93dB 6.8R and .63mH. The inductance  is too high for my application, so I would need to shunt primary with one more coil to drive inductance   down. I recognize only Bessel curve and it would be:

4kHz – 3.6uF -.43mH
5kHz – 2.9uF -.35mH
6kHz – 2.4uF -.29mH
7kHz – 2.1uF -.25mH

I was driving it up and down and as I expected the higher I cross it the better result was. It is not sound to my likening below 3K but at 6K-7K it is very nice. I think it is where I might end up using it. I did not drive the 70-20RX along with JBL LE5-2 yet – I need some kind of frame to mount them. I do not think that I will be doing it at this point… It looks like it might turn out to be an interesting upper frequency section.  Let hope that LE5 would have enough “colors” to shine through the RAAL’s neutrality. Well, from another side – the LE5 are cheap and I might experiment to soak in cone with kind of chitin or floor polishing… I can see it coming and I sell next CES the drivers that were pre-treated by boiling in collected sputter of adolescent camel.
