A friend asked me if I would be able to find a replacement inductor for his DN12 SP1004, gave me a crossover (I think, I don't know too much about the internal workings of speakers) with a burnt out inductor. (The inductor labelled 'L3' was burnt out) Would anybody be able to tell me what value the inductor is, what its internal impedence is and what sort of power it has to dissipate, so I can get a replacement for him.



The lower inductor (in the picture) is burnt out in the cross over I have.

According to Steve's schematic L3 is 0.25mH with a resistance of 0.2 Ohms.

Bet the Concerto's T27 is fried as well.

The other Concerto crossover won't be to bright either if your friend has had the wick at such a level that an inductor has burnt out.
