hey guys. how do i figure out what slope/freq i end up with if i run a signal through 2 x/overs(active).ie:two 18/db per oct set at 80hz will get me ?slope at ?freq.
Cascading two crossovers in series is generally a bad idea due to group delay, level matching issues and phase changes resulting in unpredctable bumps or dips at the crossover frequency and an introduced time-delay in your sub in relation to the rest of the system. But if everyting is perfectly matched, you will end up with 18db/oct at 80Hz.

How would he end up with the same filter if he cascades 2 of them? I haven't done much study on active filters so i dont really know what type of signal manipulation they do to achieve their band width. I can see signal delay but logically i feel like cascading would end up with a steeper slope as it is with pasive crossovers. Whats the story??
