Henry Azima left both NXT and HiWave Technologies in July 2007, on the same day. Other scientists and engineers stayed on until both companies were dissolved in October, 2013 and December 2015 respectively. They kept the research work going later at Tectonic Audio Labs and at Google LLC. So, a lot of scientific/technical changes had happened since Henry Azima's departure. He may have been the spokesman, or the one in the front for the media and such like, but there was a team. I suspect Dr. Graham Bank led the team. David Berriman, Christien Ellis, Martin Colloms, Graham Bank, Neil Harris, Andrew Marchant, for example, went to work for Tectonics, some might be still there. As the research work on distributed mode technology is an on-going project, its best to find their work, that is, if you want to make the newest clone, or get at the maths and physics of it.
There's also certain independent research going on the bending wave, transverse wave, distributed mode, balanced distributed mode etc technologies in other parts of the world, such as China, Japan, Russia or South Korea. Some are slightly translated, some are not. So, Azima is not the last and only authority on this, just one link in the chain.

Your stance keeps changing because you are just chasing your own tail going nowhere.True, I did say that. I said, more I read NXT patents, I find them more like pseudoscience. It still does, but you have to keep on reading.
And, I'd like to point out that Sandasnickaren came in with his project replyingto one my post. And, that was good turning point. He cloned the Göbel DML. That inspired me, and I read the Göbel patent. Then asked Veleric to point out to his creations. Took some time, but finally I had a look at his work. He didn't clone, but that's alright. So, one day, I said I'd read all Azima's patents. There was lot of fun comments directed at me by some, but I wanted to read, and find out. On the way, I found there are others, much more important than Azima on this distributed mode matter. So, my "stance" changes as I read.
So, I say to everyone newcomer, or who still wants to make a good distributed mode loudspeaker, just read the patents.
After a few hours, days or week you will be on another patent claiming it to be the next best thing. You are just confusing the newcomers.Is this the I have no legit rebuttal tactic so I will find fault in using the slang term yawl to change the subject?
This is similar in design to my friends panels .
I have not seen him since covid and other problems.😷
at the time he was enjoying his thin corrugated cardboard panels.
I think the panels were in the region of 1mm to 2mm, and a lot smaller in size to the one in your drawing..
I still haven't had a chance to see and listen to them, can't wait to get back to long listening sessions and tea and biscuits 😀
Steve.
yes hopefully fairly flat to 20k.
a lot of plots I have seen posted seem to drop heavily at about 10k or even lower .
a lot is to do with the panel materials and sometimes also there can be cancellations caused by the central exciter area.
But these things can be sorted out as long as the panel materials and exciter are ok.
Steve.
chdsl,
YOU started the "matter", but now that you got called out on it, you want to slink away. By the way, the correct spelling is "y'all" and it is indeed a proper word to use. It is the plural of "you", implying that "you" indicates a singular person, similar to "they and them" being the plural of "he/she" and "him/her".↑↑ @ @spedge
But, how many complete speakers/speaker systems have you made, since 2014? Can you show a picture of just one system?
That's the thing. None here, none there.
Well, you can find the other "yawl" person's username, in this post #7,780. Sure, spedge is sharp!Is this the I have no legit rebuttal tactic so I will find fault in using the slang term yawl to change the subject?
It is pretty hard to change the way one writes, however one tries to hide it, the writing style jumps out, and the emotions.
Have you written that patent, by the way?
Oh, you mean that #8,882?
I am not going back on the thread searching again, you can do that if you want, from here, #1,302 in this thread, and if you find at least one of his distributed mode loudspeakers, I'd be very glad to see that. A distributed mode loudspeaker, not an uncontrollably wobbling, flapping sheet. While you are at it, you can also search there, starting from the 2nd post. I may have overlooked one, you know.
When all else fails resort to your default setting.Well, you can find the other "yawl" person's username, in this post #7,780. Sure, spedge is sharp!

I think your post 4458 might be a good candidate for burntcoils exciter design forum?
Have you made recordings, how did it sound without the spider.
Looking at your design reminds me of a design I have seen before and used before.
I will try to cover this in later posts.
Unless someone beats me to it.
It gets a bit involved.
Steve.
I don't know, if you have this pdf already, if not, this might be of some help for your project.
The rest is in that patent.

Basically if I have a panel that is lighter than the exciter ,I just glue the panel to the coil as in the photo in this post.
But if the panel is larger and is lighter , as with EPS ,some sort of panel support will be needed.
If you have a large dog or an other half, who is very keen with the spray polish and a duster, the panel will need protecting 😲
I am lucky because I have a separate room for my audio which can be locked 😀
But I have had the occasional break in by the two creatures causing damage 😱,
For the same reason I have to use my small cone speakers for my surround speakers in my other rooms as they have to be bomb proof.
But it is up to everyone , what sort of specific protection and mounting they need for their own environment.
Steve.
yes, I had the tectonic pdf yesterday and today I read the patent well, I have a wooden frame but I have to create a rear support which, in addition to supporting the exciters, also has the task of hooking the parts of the panel with rubber or foam as well as apart from the 4 fixed points, I have to find a temporary solution for the tests and then move on to something more beautiful and stable, I don't see it as easy. What I wanted to ask is if the tectonic panels also sound on the back, on closer inspection I think so but for normal use it should cause problemsI don't know, if you have this pdf already, if not, this might be of some help for your project.

I have not heard them personally, but their YT videos say that they do. The patents, say, that
Good luck with your creation, and when you do the more beautiful one, let us know. Especially how it sounds, that is, your subjective feeling.

As a DML, they would sound on the back. The Tectonic DML500 has the same grill at the back, as seen in the YT video.

I too have my own room and two dogs. However, I've experienced few issues to date! So I'm pretty well free to try different options. Getting the H frames built for the 15" bass drivers is now the top priority.
The quest for an exciter that works a little better above that 10k hump is an interesting and important one.
Finally the multiple measuring points for the speakers has worked a treat. Even 0.5m between measuring points can result in substantial differences. A suckout in one position disappears in another and so on.
Maybe, you also employ the idea here, #8,733 as in this patent, for that? Fig. 5 description in page 64, right side, to get rid of the back sound? The two side rectangular holes would act like bass-reflex, enhancing the lows. NXT/Tectonic placed their ideas in many separate patents.

I noticed on my post before your post number 4457 that I talk about things that are still being talked a bout now,in the links posted to dml for pro use.
This was 3 years ago using my various rigid ply panels , it might be a good idea to read the whole last page on dml for pro use for some idea of what I have been talking about for all these years.
It would save me from repeating myself again and boring everyone😁
