Hi there!
I would like to understand the bass setcion of 3145 crossover that, as I presume, it is something between 290Hz and 320Hz 2nd order.
The thing is that I want to make a new crossover for the 2245H fo the 4345 with Mundorf Aronite inductors and Solen caps but my calculations gives me a 5.6mH and a 47uf capacitor followed by a Zobel network for the 1.4mH coil of the 2245H woofer with a 22uf capacitor and a 8 Ohms resistor.
Everything is fain untill I read de original crossover schematic to find 4 20uf capacitors (80uf total) followed by the zobel (20uf + 7.5ohms) and then followed by a 10uf capacitor!
Can someone explain me what the 10uf cap is doing? and why is a 5.4mH with 80uf for the woofer?
Thank you in advance....
