I’m hopping that someone has the schematic for the ATC 100 crossover
The one I can find online, is the Wilsom audio version
From the pics of my ATC SCM 100 crossovers I can see that they don’t match 100%
There is a 33 Ohm resistor in my original crossover, that’s not on the wilsom filter + I don’t trust the Wilsom filters values on the coils....
I’m really hoping that there is a kind soul in here with the real values
As I’d like not to have to disassemble my ATC’s
