I listened to these at our recent Newport highend show here in California and they are quite impressive.

Should not make any difference - you can build a single section and merely flip it upside down, thought experiment, any difference?

I think they play the same in Australia too!

Thank you. Jurgen Reis keywords helped..

I searched a little more and was able to find this site could anyone translate?

Welcome to Adobe GoLive 4

Progress is well progressing but i went into this project not even knowing what a former ( bobbin) was. I have learned a lot and am well on my way to designing the motor structure.

Btw, if I was doing the project, I would start by taking an existing speaker and excising the cone and the dustcap, leaving the spider, VC and magnet structure, brewing up some sort of mounting arrangement for the petals, and trying a quick and dirty version before committing to a complicated and expensive build... make sure you can get it to sort of work.

But first, a die cutter needs to be fabricated to cut the aluminum petals to the perfect shape. Then a corrugating rolling press needs to fabricated to roll them into the perfect curve with perfectly formed corrugations. The petals are easy to make. It's the die and press used to make them that are difficult to fabricate (extremely).Only then he can can attempt the next (dirty) step. If he can do this, I am confident that he has the will and the means to do the rest, regardless of how it sounds at the end of the process..

Dunno the google translation was plenty good enough for me... otoh I can sort of read the French, not quite well enough to get all the subtle details but to get the idea... whatever.

There are other online translations available too, so maybe a composite mental assembly after reading them all will fill the gaps?

Thanks for the translation btw first time i found out about the whole web translation.
I know enough about how the whole speakers work. I just need to get the specifics down. I kinda doubt theres any more information out there that i havent already comsumed either through text or detailed pictures. I think now its just about engineering my own drivers . But i will be taking your wise advice to build a dirty mid-range and getting it to sound "right".
