I was pointed out to Hans Deutsch website and I read everything he says, by translator. Typically, the efforts in this direction never were successful. There are plenty of the companies using acoustic, or mechanical, or electronic feedback to provide excursion compensation. There are companies who built so get along magnetic gaps or super short coils in order to keep drivers visiting constant magnetic situation. Is there very companies back in 70s who cancel suspension of drivers by applying positive current feedback to amplification and then holding the diaphragms in damping neutral zone. Is there some people in companies who introduced to drivers some obscenely compliant suspension. Like super fine leather of super fine thinners. I think all of them are completely legitimate directions to Luke but all of them accomplish the same things to drive primary residence outside of audible region and if a driver do enter primary residence then they control it electrically. It looks what Hans Deutsch that is along those lines when he electronically canceled driver resonances and inflict them but active changes in real time in crossover. Of course it is elegant. I really would like to see how he maintains face linearity while he do this but it is extremely difficult to predict how t might sound. It should be experienced in properly implemented proof of concept. I never heard it but I certainly would like to hear it. If those loudspeakers have US presents it's my refund to try them. I would like to point out that concept is well known but so far it did not become to the best of my knowledge and dominating concept for installations of this big objectives. Is it highly possible that Hans Deutsch might have good idea but doesn't have good clientele base to implement his topology or his vision at the food 100% fidelity to own topology, as so far what I have seen and the pictures are relatively small loud speakers reach might be good only for girls with banjo.

There are plenty of examples of feedback that seems to "work", from record cutting lathes to player pianos. Why have I never heard musical LF from a servo design? Not kidding here, I actually want to know if I missed something.

I think there is always a market in Germany for "Am Besten".

You can see a few clips on YouTube with Hans Deutsch implementations. Obviously, it is not the opportunity to experience Sound but the fact that it was demoed on very unfortunate equipment and regrettable music is not pleasant.  I also do not like the whole tone of Hans Deutsch, when he brings up Herbert von Karajan as some kind of reference to the superiority of Mr. Deutsch speakers. It is kind of cheesy. It is not to mention that it is well well-known fact that Herbert von Karajan spent all his life with Acoustic Research AR 303. The most important who cares what wee audio preferences of Karajan were? He deals with completely different things than what we deal with in high-end audio. It has been known for over 130 years that using those types of references addresses strictly marketing purposes and does not bring any clarity or even useful data to audio experiences. 
Saying all of it, I think it would be very interesting if Hans Deutsch presented his idea not to impress the idiots-reviewer or prospective customers but purely to push the envelope of what might be possible. If you see it expressed anywhere then, please post the link.
