I believe the same trick has been used in speakers but with the rectangular wire wound on edge to maximise the number of turns within the gap of the magnet to try and make the cone movement more linear.

Maybe I can get 5 quad turns per layer by 6 layers or = 4+ turns per layer and 7 layers for 30 total turns. If I am lucky, perhaps = a few more. > > Stretching the wire ahead of time so it's straight and binds tightly toge= ther would be good to do.
