I have designed a new full range planar speaker, for playing piano music. It is in the shape of a baby grand piano soundboard. Have placed all the neo magnets in position (1,560 25 x 6 x 3 mm neos) Just have to mark out 3 diaphragms, and put the 3 mm tape in position. Then wire it all up. Finalize the shape of the soundboard Then play some piano music.😀😎
Ha Ha! That's cute. Google Bosendorfer. It's a brand of piano.....potentially a very large piano. We've got one here with the extra low keys in Orlando at the Westin Grand Bohem Hotel. Pretty slick instrument.

small planar baby grand.
Have finished the bass diaphragm, hard on my back putting the 3 mm tape on. Also put the Astragal frame on, to hold the diaphragm tight.The medium diaphragm is next, this is smaller so will be easier on my back. Can't wait to play some piano music thro' it.😀

It is a labor of love my Friend !!!
Can't wait to see it and hear of your results !!!
Cheers !!!

Will be sending photos tomorrow.Have put the tape on the middle diaphragm, measures 4.2 ohms, perfect for amp. I hope to finish treble diaphragm tomorrow as well if the back stands up to it.I'm afraid it won't be much to look at, I'm a lousy carpenter!!
I hope you realize that if you place this horizontally the diaphragm will sag in a parabolic or if ur lucky, spherical shape due to gravity?

Minature baby grand pics.
Pics as promised, 1 more diaphragm to tape up then wiring of the 3 diaphragms, some feet then amp up and listen .Any problems will try and sort out, although I don't expect any!!😱

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?
Greg
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
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.
