That's partly true. It is also a speaker, which, from what i understand can mostly reproduce piano.

Well, I better get on designing the drum speaker and the upright bass speaker so we can at least have a jazz trio to listen to.

Looking good! Is this getting mounted in an actual piano chassis or something you are making to resemble one?

not made my mind up yet although I'm not much good at carpentry. I will see how it sounds first, if it sounds OK will probably not bother. Just 3 legs. We shall see!

If it does sag a little will probably use angle iron. The magnets are very small and the cut outs have integral struts to help. We shall see and overcome

Default last diaphragm finished

last tape in place now wants the 2 diaphragms framing. Then wiring up and trying I may reshape the soundboard to make it look more like a piano, a very small one, but I don't have much room left, to put it anyway. The small magnets helped, it's lucky I had them, otherwise it would have been too big and heavy. So wouldn't have materialized.
