The last couple of months has seen a silly rise in the price of coils,possibly due to the copper price? I know commodities are expensive and Goertz has put a fat margin on the non-copper component (if you know the weight you know the copper content just about) but I am starting to look at turning wooden formers (say use some of those maple offcuts) and wind using some 1.4mm wire. Now, where can one buy insulated wire (perhaps even in Pretoria?) without having to buy a 500m roll?
I had to abandon a very clever design for my latest HT install becasue of the coils alone would've set me back more than the 12" mid-bass driver (then there was the thing with 120uF total capacitence in the design,the new one has a mere 40 and half the copper)
