I know I need to find someone who can do some CNC ( tried before to use stock pieces glued together but i could not get the right gap width). Likely cheaper then getting customs magnets!
What Salhaga made is basically a radial motor very similar to vivid audio. Good design but it is hard to find true radial magnets and even harder still to make them out of arc segments. Then you have the difficulty of putting the motor together this makes it VERY impractical for a diyer. It seems what you are attempting is basically a Manger speaker. I believe Manger is as good as it gets for flat BWS. You may as well purchase Manger then again it is a diy site and I want to develop a bending wave driver although I dont think there is anything left to do with flat BWS. If you need someone to bounce ideas around or make a few models feel free to contact me.
Actually I had Manger MSW drivers for many years. One of them deteriorated and I tried to find a replacement but then I thought DIY. Also Manger stopped to sell to DIY. At least sonically and also measurement wise I achieved a better driver from 350 Hz past what I can measure and hear (20kHz). But then one can always make it better thus this thread. As it is a linear or rectangular design I am using block magnets and not arc ones. Assembly is not completely easy but not too difficult if you learn to keep your fingers away from where they should not be and use jigs.

From what I have seen Manger drivers are top notch. What do you see in Manger drivers that could be improved? I would assume you want to make a rectangular driver for increased surface area and such. What other things do you hope to change? If you want to keep things to your self I understand.
Manger are good drivers being wide band and bending wave but their design did not improve for at least 2 decades. Here is a link to a thread about some improvements:

My design uses a stiffer plate but it is a work in progress; therefore this thread about linear VC and its motor design.

I see I Know you could better the Manger just didn't know where the weaknesses were. Moongel is interesting I have a very similar thing going into my speakers Moongel is vinyl Mine is silicone. Please post your progress on the motor I will be attempting it myself in the future.
