Got today the parts and finalized the “perfect” Bessel passive crossover for my new channel. The coils are regular air-core 2.5H and 7H, the caps are Theta 10uF and the small wirewound tuning resistors that kills ~1.5dB in the channel. When I put all together everything came together. What the beautiful result!!! The most wonderful in it this, beside the sound itself, is that by tuning the resistor -/+ 1 dB it is possible very precisely dial-in the weight of the MF balance and it affects presentation very-very-very interestingly. My initial intention was to put there a small L-pad but then I realized that after a couple days of listening and finding the correct balance I would not need it any adjustability in there anymore. I think it will be something between 1Ohm and 2Ohm dropping resistor before the first coils.
Sometimes what I have time and intention I will try to drive the thing with own amp and a line lever filters…
But for now, the chanall and the Macondo do very excellent, they well fulfills my expectations and I’ very happy Cat.
