hi,
I wanted ask to HI-VI,
but not possible contact they,
so I ask to someone expert in isodinamycs ,
which is the maximum value for in series cap to put in to measure the frequency response with 2,83 volt,
because the datasheet seems to me unrealistic( perhaps half-space)
thanks for help
cheers

This driver is not a true-ribbon, so a capacitor is not absolutely mandatory to save your amplifier, but a 25uF would not be out of the question to measure the response.

Hi,
I have a pair of these too.(did not measure them) It was tested some years ago in the German Magazine Hobby Hifi. The graph in this doc is from the Hobby Hifi test. That should be a precise measurement. Please notice Hi-Vi stopped producing this +-100dB planar. So If you plan a new speaker with it, that might become a problem.

Ok, Enjoy! Hobby Hifi magazine used this planar in their referenence (hate that word MkIII) speaker Optimum. Some hornpeople may be interested in this tweeter Only other planar +- 100 dB option is this one: http://www.expolinear.de/images/stories/expolinear%20rt-8%20pro.pdf

Please note it is still on their website:
Overview of RT2-Pro Drivers_HiVi,Inc
It is still available for sale from 1 vendor in North America; Solen.

I said it's not a true ribbon, so it's impedance does not dip and won't hurt an amplifier.
Did you miss that?
BUT- unless you want to blow the tweeter when doing a sweep, a 25-40uF cap is advised. It's for the tweeter, not for the amp. You can't play bass through a ribbon or planar and have it survive very often.
