A newbie, here, who desires enlightenment.
Can someone explain to me why DIY folks say that copying the networks / crossovers of these old JBL systems can be one of the more difficult aspects of their build?
In many instances we have the old speaker systems intact as well as some of the schematics, so we know what resistors and capacitors etc. are being used, and we know at what Hz. the crossovers are being implemented.
I'm clearly missing some principle in this process.
