The saved links for Podium speakers I had do not work anymore. Podiums exciters were mounted rigidly to the spine and the circle discs were placed on the spine. You can use any type of damping material on the spine and or if you do not use a spine you can put it directly on the magnet.
Exactly my findings also, maybe I should re visit EPS again with this new exciter.
I remember hearing the podiums years ago when they first came out at a hifi show in Manchester. That's what got me started in the first place.
I heard them down south , can't remember which audio show.
I remember saying to my wife I could convert an electric piano to use dml panels to sound exactly like a real piano.
It would save a fortune on a real piano and the expense of continually tuning.
She said NO !, I want to feel the piano 😩
my poor wallet 😬

I have those links but those dont show the disc used for tuning. There was another link clearly showed it but that link no longer works.
I don't seem to be able to use my phone to reply, it now starts editing the reply ?
It also starts putting in huge amounts of spaces a mile long?
I have to use my tablet to delete it.
Has anyone experienced similar problems ?

You did well with using Tesa Moll tapes on the perimeters of your Göbel clone build., even though they are made from synthetic rubber, as rubber eats the sound.
As everyone here has EPS (or XPS) sheets, why not cover it tightly with Cling film (Cling wrap) to see how the sound changes? Practically every kitchen has Cling film these days.
As it happens, I am in the middle of testing cling film on various panels mainly the heavy panels.
This is to replace the paper strips , but I have not made up my mind if it works or if it is an improvement ?
I wasn't going to mention it until I had made a decision.
I am more interested in using the cling film in the exciter area as a passive radiator a sort of electrostatic or planar without electrics or magnets.
Work in progress.

Good that you are trying cling film. Tell us your subjective feeling, how the panels sound, near-field and far field, and at an angle, on in-plane, etc. Also, fix the panel to a frame with double-sided foam tape to see how the sound changes. If you don't have a frame at hand, just fix the frame to the wall, that is, if you have a brick wall. You may need few strips of that tape to match the thickness of the exciter, if you fix the panel on the wall, though.

Right as requested some pictures of the build, added a final sheet of corrugated cardboard/ paper, the difference that has made to the bass has surprised me, these things really kick down low now.

It's a hole where I tried a fullrange driver, didn't work. If I had a small 19 mm exciter at hand I would try it on this spot tho, got a nice top end tap sound to it.
The idea for the cling film is loosely based on this patent.
Instead of the panel(film) being driven by the cone driver it is being driven by the panel surface .
The thin strips of paper I used do the same job.
This all stems from something a friend commented on his panels many years ago.
