There is no passive crossovers. These drivers are exclusively fully active. They were never tuned for anything but their current in-wall home. If you'd like, I can list drivers with their various t/s and response, my own readings, the current crossover and EQ settings per driver channel, amps, etc. but I think that would be better suited for another thread. (which I plan to start eventually)
My point of this thread is to simply save me time in removing the diffusers next to my front L/R custom-built channels and trying absorption or a hard surface and testing by using other user feedback. Youtube channel "
AVPro Edge" has plenty of great videos on acoustics, but doesn't quite address my circumstances.
