Plate Reverb pre EQ Issue

[RoadrunnerOZ]

Ecoplates had stainless. If you think Ecoplates had cold rolled steel please post a source.

The original plate was cold rolled or stainless:

@RoadrunnerOZ "the thinner the plate material needs to be but the more air resistance damping comes into play." What does it mean?

"so as it seems you’re planning on using springs" I must say that I have not.

Air resistance to movement will have a greater back effect on the lighter material so ring time is reduced - the input signal is short but the plate ring-on time is dependent on the mass of metal moving and the factors that impede that movement - as it has a large surface area the air damping factor is considerable.
As far as the springs go you posted a video of the construction of a plate which I assumed patterned what you were going to build - post #61 - that construction uses springs - shown at 02:00.

That was before the alchemical secrets of Hermes were revealed to me. Now I can see more clearly what needs to be done!
