US source of Panzerholtz?

I know this thread has been sleeping for a while now. I am discussions with my former employer about building his latest designed speaker in USA.
He was the one who suggested Panzerholz (Panzerholtz) to me.

When I worked for him, we were building out of HD3, made from New Zealand hardwoods with a resin. HD3 is 1.6 times as dense as HDF,
however it is not made anymore. I'm looking for something like that again, to laminate 4mm steel plate to, for our enclosures.

Thank you, this is a very informative thread. Materials are so much cheaper here than back home. I'm excited to get going on this.

Rix, 4 mm steel plate? For a speaker enclosure? Do you have any idea of how much that would weight? How big is the speaker? Another issue is that steel rings, aluminum does not. My buddy's Magico S7s are aluminum and they weight 300lb each!

@mijostyn
yes I do know how much it weighs, every time I am foolish enough to move my stand mount speakers. You can barely see the steel plates affixed in my system page, and I'm guessing your eyes will roll when I mention two of the four cross braces are inch and a half solid cast iron rod.

Using the same epoxy used to build Maxi racing yachts, the steel plates do not ring when laminated to HD3, or HDF, or MDF. What they do accomplish is change the resonant frequency, moving them out of audible range (well, mostly where they will least impact overall sound). My speakers with a rap of the knuckles sound somewhat like a dinner plate, but much more inert.

I think my grey pair of speakers weigh something like 98lbs each. About the same as my welded steel stands.

Aluminum absolutely rings. https://www.lessloss.com/page.html?id=80
Of course geometry is as important as materials used, the Magico have a reputation of engineering prowess.

I just finished installing a Pz tonearm wand. Sounds better with every listening session!

Delignit have been increasing thier product range and P'holz has evolved in the types available.
There is now a CarbonWood (P'holz / Carbon Fibre Lamination) as well as few others.
