Something like this is better then. I posted before having a good look at the scheme, my bad.Note that the 3.7mH coil in the original crossover has 3.25 ohm resistance and this is intentional
If you ask the reseller, he'll gladly inform you how to make a 3,7mH coil from this 3,9mH coil by unwinding it a bit (about 2% would do, so if the coil has 200 windings, unwind 4).
