First step in 120*3cm ribbon. The ribbon is made of 4my aluminium with glued 20 my capacitor paper on both sides. This done so it only needs very little corugation, and to prevent it from bendig as it heats up. The metal is 1*4 cm and magnets 1*1*15cm

Good to see you back.4my alu is very thin.

Thanks Bernt. Don't now how it sounds have made what is seen 🙂. I think the foil is from Jensen capacitors. Dont remember got the roll some 20 years ago. My plan is to make the ribbon as simple as possible crossed over to 4 6-7 inch midranges and a AE 18'' .

Magnetsystem is going to bee very heavy.
Is the double magnets for stronger magnet field?
How wide will the ribbon be?
Hope you get a good sounding result

Heavy 8-10 kg . Will glue it to the baffle, so it will stiffen it. Yes the double magnets is for a stronger field. The field will be 35 mm. The ribbon 32-33 mm wide

where did you got 4 My alu !!! i wonder 🙂 i was looking for it like 1000 years ! nice project ! by the way ill gone watch diyaudio some more, i miss all the guys that are making cool s tuf themselfs !
Hej WrineX
The magnets are N35 still powerfull 🙂. The hard part wil be to assempel the 2 sides without loosing any fingers. The alu foil is from Steen Duelund the founder of Duelund coherent audio. Think he got it from Jensen capacitors they produce their base to coils and capacitors. But he has dead 10 years now

Starting with a sealer can keep the MDF from sucking up so much paint.
Some people paint on diluted wood glue to achieve the same thing.
Lots of materials to do it, and not much consensus in what I've read.

Some people like shellac for sealer also. It's not completely clear, but with a black background the orange tint is probably irrelevant.
