Magnepan/ESL combo - Page 4

WrineX · 13th February 2011, 06:37 PM

i believe the tension of magnepan is really high. so stretching it then heat treat i wil become more sloppy then it whas before the heatgun action. and my bed is when the tension it to low it will wack into the magnets.

but let us know i have 4 smg's here that i wanted to do the same thing with addig esl from 300 and up let the magnepan do the thing there pretty good in, the lower octaves without havng to have panels great as doors in ur living room.

[QUOTE=john65b;2409476]I have rewired many Magnepans, and for tweeter section rewires, I just used Copper Magnet wire from Radio Shack. Worked perfectly. Originals are aluminum, but the Copper may be a bit of an improvement if you ask me.

it adds weight so its certainly not an improvment. thats the reason they use al

especially the tweeter part beter be as light as possible.

you could use this tape they use in security to tape on windows. its really thin.

I think the additional weight of copper wire glued to the mylar with DAP Weldwood would be far less than the aluminum wire with the 3M Super 77 spray glue and Milloxane that was stock and often recommended as a fix

If you apply some DC voltage to the conductors, it and the magnets should hold the conductors in perfect position, for the glue application and curing.

So then, of course, using aluminum wire or foil with the DAP should weigh even less. <smile>

But if the wire you used can handle the current, without heating too much, and its mass is low-enough, it should be fine.

We did a little work on the relationships between aluminum wire and foil sizes, lengths, resistances, and weights, a while back, at:
