Yes, I know that. Does your sheet has tiny canals, or honeycomb. I haven't seen a Proplex sheet with honeycomb structure.
Oh, I thought it was polycarbonate. Some others advertise Proplex as that. Does your sheet has tiny canals, or a honeycomb?

So, the panel is not that stiff on the parallel direction. How do you hear the sound, if you change directions of the flutes horizontally to vertically, and vice versa? Does it change? I mean your subjective feeling.
No just simple stiff cardboard, I think my journey has ended , can't see I can improve in the sound I'm getting now . Just need to make them look more attractive.
The 6mm proplex is too heavy for just one of my exciters unless I xo higher up ,say 200hz.
I'm still trying to think of ways to improve it, sound wise , maybe using paper strips .
I have been toying around with some ideas on more rigid panels, but am not sure if it actually works.
More testing and listening needed.
The frequency response is pretty much perfect, so I do not want to muck that up.

I think it was, might be ok as a upper mid tweeter panel, but not what I was looking for, then again it could have been an exciter issue. Give it a try tho and let us know what you think.
I found the 4mm corflute (same as proplex) to perform very well...I was very surprised..Just a tad soft on the highs which was fixed by my normal method. It's quite easily driven as well. I'm surprised Steve finds it heavy.. My calcs indicate that it's less than half the mass of Poplar ply of the same thickness

Well, Karavashkin is not an authority for you, so look at an authoritative publication and think about how to improve the DML panel. And this information will help you 😏
Can you tell more about that cardboard? Thickness, length and breadth, and whether it is a honeycomb one? Thanks.
I'm worry? You are confusing something, anxiety is just observed in you)
Well, Danilo Herger's 3rd Russian patent RU2744773C1 applied on 10.08.2020, granted on 15.03.2021 mentions Karavashkin "thesis" and the image of the constructed speaker, reminds me of Mescalito speakers.
And the so-called Transverse technology,
is included in the patent. Herger's US patent application
