Very nice, I like the pattern.

Did you weight it? Hope the voicecoil/cone joining point is strong.

Nice cones tinitus, like Hentia I like the patten to. Is that Kapton you use for coil former?
Will you make a short description on how you made it, always looking to learn new stuff.

Where did you get the pigytail wire?

Take care.

I made this 'mold'
voice coil is put on the centre tap
and diaphragm/cone is molded directly on to it
if needed I can put on more reinforcement on the back

it was supposed to be a midrange only
didnt have ambitions for the heights

Nice job, tinitus. It looks like you have treated some kind of cloth, is that correct and if so what is the base material.

Take care

Got the field coils from Hentai today, he did a amassing job. I put on a basket and a cone just to see, it looks wild..Here is some pic's.

Next step is to design a strong basket for the unit.

Take care

That looks like fun!
My respects for very impressive work by Hentai.
Serious postal costs too, I expect!

Best wishes

Thank you David,
Postal cost can get high yes due to weight. On these it was about 100E.

tinitus, you gave me a idea, thanks.....Using a spider could work if it was softer and airtight, I spend some time to figure it out how to losses up the addictive in the spider. I found that ammonia dose the trick, next step is to get it airtight. I found that latex milk dose contains ammonia and can seal the holes in the spider at the same time... and what do you know.... it's works beautifully. Took some pic's.
