Mid-range/band pass question

3-LockBox · 28th September 2007, 07:56 PM

Researching the different types of crossover circuits, I see that there are different phase effects inherent in all of them.

As for band pass filters, here's my guestion: Are they self correcting?

I ax that question because, for example, a second order, -12db slope crossover has an inherent 180 degree phase inversion, I assume, in the cut off stage, but what of the roll off stage; does it too, invert the signal?

50 views and no answer? Should I reword the question?

3-LockBox , you have to consider where the other drivers are and what order they have in the xover.
But, of course it varies in frequency.

Hi, No. Bandpass 12dB/oct either side phase wraps 360 degrees,
