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

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'' .

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
