your diver might be a very good MF diver but it does not go to region where the “tizzing” live.

You may not believe me, but the driver start to  roll off (very smoothly) after 14kHz and at 20kHz is at -6dB. I intentionally do not use it so high, because I have ultra light weight alnico paper tweeter: http://www.bgaudio.org/forums/viewtopic.php?p=9833971#p9833971 
So my eliptical driver is able to reproduce almost all of the high frequency information, and as I already said - without any trace of harshness.

It just has too large and to heavy diaphragms for it

The diaphragm do not work as a piston, but it features a progressive fracturisation, and this is the only way to get a proper and natural sound with direct radiators. According to your assumption that it is heavy - the diaphragm and voice coil assembly weight exactly 4,4 grams, so it can reproduce effortlessly transients and critical upper midrange - low HF zone.

(Telefunken, Klangfilm, Tesla and few others) ... However, you can’t not make the claims that those drivers does not do “tizzing” as they are juts MF diver and perform more or less comfortable in sub 7kHz area.

I completely argee with that statement!

you claim that you were not able to make a PS that would power your driver to a sufficient level of sound? Are you sure about it? At 12V you can use 5F-6F car capacitors that shall cancel any PS influence

My field coils are powered ot 120V, not at 12V, and the batteries are wired in series

it is very difficult to evaluate how effective all of it and how it sound in reality unless one heard the thing.

Welcome in Bulgaria, you might learn a lot about Absolute Tone Smile
