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.:D:cool::hohoho:
 
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.:hohoho::D
 
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!!:eek:

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.
